ABRO Grey 999® RTV Silicone Gasket Maker in Kenya
When an engine starts leaking oil, coolant or other fluids, the real problem is often not simply the gasket itself. The failure may result from heat, vibration, thermal expansion, poor surface preparation, flange movement or the use of an unsuitable gasket sealant.
That is where ABRO Grey 999® RTV Silicone Gasket Maker comes in.
ABRO Grey 999® is a high-performance grey RTV silicone gasket maker designed specifically for import engines and precision automotive applications. It is formulated to create a tough, flexible and durable seal while offering high-temperature resistance of up to 650°F or 343°C. ABRO also specifies that the product is oxygen sensor safe, features a neutral cure, low-odour formulation, and is designed to provide reliable sealing for demanding automotive applications.
For mechanics, automotive workshops, engine rebuilders, fleet maintenance teams and serious DIY vehicle owners, choosing the right gasket maker matters.
Using a cheap or unsuitable sealant may appear to save money during the repair. But if the seal fails, the actual cost becomes much higher:
Remove the component → clean the surfaces again → buy more materials → repeat the labour → deal with the customer complaint.
That is poor cost management.
ABRO Grey 999® is positioned for users who need a professional RTV silicone gasket maker for suitable engine and mechanical sealing applications.
What Is ABRO Grey 999® RTV Silicone Gasket Maker?
ABRO Grey 999® is an RTV, or Room Temperature Vulcanizing, silicone gasket maker.
RTV silicone is applied as a liquid or paste-like material and cures to form a flexible rubber-like seal.
Instead of relying entirely on a pre-cut gasket, an RTV gasket maker can be used in suitable applications to create a form-in-place gasket.
The sealant conforms to the shape of the mating surfaces, helping create a continuous sealing barrier where the product and application are compatible.
ABRO identifies Grey 999® as being specifically designed for import engines and suitable for demanding automotive sealing requirements. Its official product information highlights its oxygen sensor-safe formulation, neutral cure technology, low odour and high-temperature capability.
The product is supplied in a grey colour and the standard tube version is identified by ABRO as Part No. 9-AB, 3 oz / 85g.
Why Choose ABRO Grey 999® Instead of an Ordinary Silicone Sealant?
Not every silicone is designed for the same job.
This is where many buyers make the wrong purchasing decision.
A general-purpose silicone sealant may be suitable for construction, sanitary or household sealing. That does not automatically make it suitable for engine components.
Automotive engines operate under demanding conditions involving:
- High temperatures
- Thermal cycling
- Engine vibration
- Oil exposure
- Mechanical movement
- Pressure
- Metal expansion and contraction
A gasket maker must therefore be selected according to the application.
ABRO Grey 999® is specifically designed for automotive gasketing and import-engine applications. ABRO identifies the product as a high-performance, neutral-cure RTV silicone designed for precision engine components and states that it forms a durable, flexible seal.
The objective is simple:
Use a gasket maker designed for automotive sealing instead of forcing a general-purpose sealant into an engine application.
High Temperature Resistance up to 343°C
Heat is one of the biggest enemies of an unsuitable gasket seal.
When an engine heats up, metal components expand.
When the engine cools, those same components contract.
This process is repeated continuously throughout the operating life of the vehicle.
A gasket material that cannot cope with the application's temperature requirements may eventually harden, crack, shrink or lose sealing performance.
ABRO states that Grey 999® is effective at temperatures of up to 650°F or 343°C.
This high-temperature capability makes the product relevant for suitable automotive applications where heat resistance is an important requirement.
However, the temperature rating alone should not be used to select a gasket maker.
The correct product selection must also consider:
- The component being sealed
- The fluids involved
- Surface material
- Flange design
- Manufacturer recommendations
- Actual operating conditions
A high-temperature product is not automatically the right product for every high-temperature location.
Oxygen Sensor Safe Formula
Modern vehicles rely heavily on electronic and emissions-control systems.
The oxygen sensor is one of the critical components involved in engine management and emissions monitoring.
ABRO specifically states that Grey 999® is formulated to be oxygen sensor safe.
This is an important consideration when selecting gasket-making products for modern vehicles.
The wrong chemical formulation can potentially create unnecessary compatibility concerns around sensitive automotive systems.
Grey 999® is also described by ABRO as a neutral-cure and non-corrosive formulation, which is relevant for sensitive automotive components and metal surfaces.
For workshops working on Japanese, European and other modern vehicles, selecting an appropriate sensor-safe gasket maker is simply better technical practice.
Designed for Import Engines
ABRO specifically positions Grey 999® for import engines.
This makes the product particularly relevant for many vehicles commonly found in Kenya, where Japanese and European vehicle brands represent a significant part of the automotive market.
The term "import engine" does not mean the product is restricted only to imported vehicles.
ABRO's own gasket maker information states that Grey 999® is specially formulated for import engines but may also be used on suitable U.S. engine applications.
The key consideration is not where the vehicle came from.
The key consideration is:
Is Grey 999® technically suitable for the specific component and sealing application?
That question should always come before applying any gasket maker.
Common Applications for ABRO Grey 999®
According to ABRO's product information, Grey 999® can be used as an ideal gasket replacement for suitable applications including:
- Cam covers
- Transmission covers
- Thermostat housings
- Intake manifold seals
- Oil pans
- Water pumps
ABRO also describes the product as suitable for engine, transmission and other critical sealing areas in appropriate applications.
Let's look at these applications in more detail.
ABRO Grey 999® for Cam Covers and Valve Covers
Cam covers and valve covers are common areas where oil leakage can occur.
Over time, seals can deteriorate due to:
- Engine heat
- Age
- Vibration
- Improper tightening
- Damaged sealing surfaces
Where the manufacturer's repair procedure allows the use of RTV silicone, ABRO Grey 999® can provide a flexible sealing solution.
However, do not automatically replace a designed rubber or pre-cut gasket with RTV silicone.
Some engines specifically require a replacement gasket.
Others may require RTV only at particular joints or corners.
The correct procedure is determined by the engine manufacturer's repair requirements.
The professional approach is:
Follow the engine specification first. Select the sealant second.
ABRO Grey 999® for Oil Pans
Oil pans are exposed to continuous contact with engine oil.
They also experience:
- Engine vibration
- Thermal cycling
- Road vibration
- Mechanical movement
ABRO specifically lists oil pans among the typical applications for Grey 999® RTV Silicone Gasket Maker.
Before application, the old gasket material and previous sealant must be removed properly.
The mating surfaces should be inspected for:
- Warping
- Cracks
- Corrosion
- Deep scratches
- Damage around bolt holes
A gasket maker cannot reliably correct a severely damaged or warped oil pan flange.
This is where many repairs go wrong.
The mechanic sees a damaged flange and responds by applying more silicone.
That is not engineering.
That is gambling with the repair.
Fix the mechanical problem first.
Then apply the correct gasket-making product according to the recommended procedure.
ABRO Grey 999® for Thermostat Housings
Thermostat housings require effective sealing because coolant leaks can create overheating problems.
Depending on the vehicle design, a thermostat housing may use:
- A rubber seal
- An O-ring
- A pre-cut gasket
- RTV silicone in specified locations
ABRO identifies thermostat housings among the suitable gasket replacement applications for Grey 999®.
Again, the product should be used only where appropriate.
RTV silicone should not be applied as a substitute for every thermostat housing gasket without checking the correct repair procedure.
ABRO Grey 999® for Water Pumps
Water pumps require reliable sealing because even a small leak can lead to coolant loss.
ABRO lists water pumps among the applications suitable for Grey 999® gasket replacement.
The quality of the final seal depends on more than the product itself.
You also need:
- Clean mating surfaces
- Correct installation
- Proper bolt tightening
- The correct gasket or sealant procedure
Do not use excessive amounts of silicone simply because the component handles coolant.
More product does not equal better sealing.
A controlled and continuous application is generally the professional approach.
ABRO Grey 999® for Transmission Covers
Transmission assemblies may experience fluid exposure, temperature variation and mechanical vibration.
ABRO specifically lists transmission covers as a suitable application for Grey 999® in appropriate gasket replacement work.
As with any mechanical seal, compatibility with the transmission fluid and manufacturer's service requirements should be confirmed before use.
Never assume that every RTV silicone is suitable for every automotive fluid.
ABRO Grey 999® for Intake Manifold Sealing
ABRO identifies intake manifold seals among the suitable applications for Grey 999®.
However, intake systems are precision assemblies.
Incorrect sealant application can potentially interfere with airflow passages or other components.
Use only the quantity required and follow the manufacturer's recommended application points.
Do not apply RTV indiscriminately around an intake system.
How ABRO Grey 999® Works
Grey 999® is a one-component RTV silicone.
The sealant is applied directly to a properly prepared surface.
After application, the material cures to form a flexible seal.
The basic process is:
Apply → Assemble → Cure → Seal
The simplicity of the process does not mean the application can be careless.
A professional-quality result depends heavily on preparation.
Surface Preparation Is Critical
Even the best gasket maker can fail when applied to a contaminated surface.
Before applying ABRO Grey 999®, the surfaces should be properly prepared according to the relevant instructions.
Remove:
- Old gasket material
- Previous silicone
- Oil
- Grease
- Dirt
- Loose particles
- Other contaminants
The surface should then be inspected.
Look for:
- Cracks
- Distortion
- Deep scratches
- Corrosion
- Uneven surfaces
- Damaged bolt areas
If the mechanical surfaces are severely damaged, applying more sealant is not a real solution.
This is a critical point for automotive workshops.
A gasket maker seals a suitable joint. It does not rebuild a damaged engine component.
How to Apply ABRO Grey 999® RTV Silicone Gasket Maker
The exact procedure should follow the ABRO instructions and the vehicle or equipment manufacturer's repair requirements.
A general process is as follows.
Step 1: Remove the Old Gasket
Carefully remove old gasket material and cured sealant.
Avoid damaging the mating surfaces.
Step 2: Clean Both Surfaces
Remove oil, grease and contaminants.
A contaminated surface can compromise adhesion and sealing performance.
Step 3: Inspect the Flanges
Check for warping, cracks or damage.
Correct mechanical defects before applying the sealant.
Step 4: Apply a Continuous Bead
Apply the sealant in a controlled and consistent bead according to the component's design and manufacturer recommendations.
The bead should be continuous where a continuous seal is required.
Step 5: Assemble Correctly
Position the components according to the repair procedure.
Follow the recommended bolt tightening sequence and torque specifications.
Step 6: Allow Proper Curing
Allow sufficient curing according to the product instructions and application requirements before exposing the assembly to service conditions.
Do not assume the sealant is fully cured simply because the surface appears dry.
The Biggest Mistake: Using Too Much RTV Silicone
One of the most common workshop mistakes is excessive silicone application.
The logic usually goes:
"If a small amount seals, a large amount will seal better."
Wrong.
Excessive product can:
- Create a messy repair
- Waste sealant
- Squeeze beyond the sealing area
- Make future disassembly more difficult
- Potentially extrude into unwanted areas depending on the assembly
The goal is not to use the most sealant.
The goal is to create the correct seal.
A controlled bead is more professional than an uncontrolled mass of silicone.
ABRO Grey 999® and Engine Vibration
Engines do not remain static during operation.
They generate vibration.
They also experience repeated heating and cooling.
A suitable gasket maker must therefore maintain sealing performance under changing conditions.
ABRO describes Grey 999® as producing a durable, flexible gasket suitable for automotive sealing requirements.
Flexibility is important because rigid sealing materials may struggle where movement and thermal expansion occur.
Again, the product should be used within its intended application requirements.
ABRO Grey 999® for Professional Automotive Workshops
For a professional workshop, the cost of a product is only one part of the equation.
The more important question is:
What happens if the repair fails?
A failed seal can result in:
- Repeat labour
- Loss of workshop time
- Customer dissatisfaction
- Additional material costs
- Damage to business reputation
The cheapest gasket maker can therefore become the most expensive option.
ABRO Grey 999® provides a specialised option for workshops dealing with suitable automotive gasketing applications, particularly import-engine and precision sealing work.
Its combination of:
- High-temperature resistance
- Oxygen sensor safety
- Neutral cure
- Low odour
- Non-corrosive formulation
- Flexible sealing performance
makes it a strong candidate where its technical properties match the repair requirement.
ABRO Grey 999® for Japanese Vehicles
Kenya has a large number of Japanese vehicles on the road.
Common brands include Toyota, Nissan, Mazda, Subaru, Honda, Mitsubishi and Suzuki.
These vehicles have different engine designs and service requirements.
Therefore, avoid the mistake of saying:
"This is for Japanese cars, so it works everywhere on every Japanese engine."
That is not technically correct.
ABRO Grey 999® is designed for import-engine applications, but each specific repair must still follow the vehicle manufacturer's requirements.
The right question is:
Does this component and repair procedure require or permit this type of RTV silicone gasket maker?
If yes, Grey 999® may be the appropriate solution.
ABRO Grey 999® for European Vehicles
The same principle applies to European vehicles.
Engine and transmission systems may have specific requirements regarding:
- Gasket material
- Sealant chemistry
- Fluid compatibility
- Application thickness
- Torque procedures
Do not apply RTV silicone to a European engine simply because it is a premium product.
Technical compatibility comes first.
Where a grey, neutral-cure, high-temperature RTV silicone is appropriate, ABRO Grey 999® provides a professional option.
Is ABRO Grey 999® the Same as Ordinary Grey Silicone?
No.
The product should not be confused with general-purpose grey silicone sealants.
ABRO positions Grey 999® as a high-performance automotive gasket maker with properties designed for demanding engine applications.
Its key characteristics include:
Feature ABRO Grey 999®

ABRO Grey 999® vs Other ABRO Gasket Makers
ABRO manufactures several gasket-making products.
Choosing the correct one depends on the application.
For example, ABRO's standard RTV silicone gasket maker range includes products designed for general automotive gasketing, while its Red RTV and Ultra Plus ranges are positioned for different temperature and performance requirements.
Grey 999® is specifically positioned for:
- Import engines
- Precision automotive applications
- Sensor-safe sealing
- High-temperature applications up to its rated limit
- Flexible gasket formation
The best product is not necessarily the most expensive or the highest-temperature option.
The best product is the one that matches the application.
ABRO Grey 999® vs Pre-Cut Gaskets
This is another area where customers need to be careful.
RTV silicone gasket makers can create form-in-place gaskets.
However, that does not mean they should replace every factory gasket.
Some components require:
- Specific rubber gaskets
- Multi-layer steel gaskets
- O-rings
- Composite gaskets
- Manufacturer-approved sealant
In certain applications, RTV is used only as an additional sealant at specific points.
Never assume that removing the original gasket and applying Grey 999® is the correct repair.
Always check the service procedure.
Who Should Buy ABRO Grey 999®?

Buying the wrong sealant costs time.
A quick technical check before application can prevent a repeat repair.
Safety and Handling Considerations
ABRO's Safety Data Sheet for the Grey 999® product identifies safety considerations associated with the uncured sealant, including potential skin sensitisation and hazards from prolonged or repeated exposure. Appropriate protective equipment and handling precautions should therefore be followed.
Good workshop practice includes:
- Using appropriate protective gloves
- Avoiding unnecessary skin contact
- Working in a suitably ventilated environment
- Following product label instructions
- Keeping the product away from children
- Following applicable disposal requirements
Always refer to the product label and current Safety Data Sheet for complete handling and safety information.

- Old gasket material
- Previous silicone
- Oil
- Grease
- Dirt
- Loose particles
- Other contaminants
The surface should then be inspected.
Look for:
- Cracks
- Distortion
- Deep scratches
- Corrosion
- Uneven surfaces
- Damaged bolt areas
If the mechanical surfaces are severely damaged, applying more sealant is not a real solution.
This is a critical point for automotive workshops.
A gasket maker seals a suitable joint. It does not rebuild a damaged engine component.
How to Apply ABRO Grey 999® RTV Silicone Gasket Maker
The exact procedure should follow the ABRO instructions and the vehicle or equipment manufacturer's repair requirements.
A general process is as follows.
Step 1: Remove the Old Gasket
Carefully remove old gasket material and cured sealant.
Avoid damaging the mating surfaces.
Step 2: Clean Both Surfaces
Remove oil, grease and contaminants.
A contaminated surface can compromise adhesion and sealing performance.
Step 3: Inspect the Flanges
Check for warping, cracks or damage.
Correct mechanical defects before applying the sealant.
Step 4: Apply a Continuous Bead
Apply the sealant in a controlled and consistent bead according to the component's design and manufacturer recommendations.
The bead should be continuous where a continuous seal is required.
Step 5: Assemble Correctly
Position the components according to the repair procedure.
Follow the recommended bolt tightening sequence and torque specifications.
Step 6: Allow Proper Curing
Allow sufficient curing according to the product instructions and application requirements before exposing the assembly to service conditions.
Do not assume the sealant is fully cured simply because the surface appears dry.
The Biggest Mistake: Using Too Much RTV Silicone
One of the most common workshop mistakes is excessive silicone application.
The logic usually goes:
"If a small amount seals, a large amount will seal better."
Wrong.
Excessive product can:
- Create a messy repair
- Waste sealant
- Squeeze beyond the sealing area
- Make future disassembly more difficult
- Potentially extrude into unwanted areas depending on the assembly
The goal is not to use the most sealant.
The goal is to create the correct seal.
A controlled bead is more professional than an uncontrolled mass of silicone.
ABRO Grey 999® and Engine Vibration
Engines do not remain static during operation.
They generate vibration.
They also experience repeated heating and cooling.
A suitable gasket maker must therefore maintain sealing performance under changing conditions.
ABRO describes Grey 999® as producing a durable, flexible gasket suitable for automotive sealing requirements.
Flexibility is important because rigid sealing materials may struggle where movement and thermal expansion occur.
Again, the product should be used within its intended application requirements.
ABRO Grey 999® for Professional Automotive Workshops
For a professional workshop, the cost of a product is only one part of the equation.
The more important question is:
What happens if the repair fails?
A failed seal can result in:
- Repeat labour
- Loss of workshop time
- Customer dissatisfaction
- Additional material costs
- Damage to business reputation
The cheapest gasket maker can therefore become the most expensive option.
ABRO Grey 999® provides a specialised option for workshops dealing with suitable automotive gasketing applications, particularly import-engine and precision sealing work.
Its combination of:
- High-temperature resistance
- Oxygen sensor safety
- Neutral cure
- Low odour
- Non-corrosive formulation
- Flexible sealing performance
makes it a strong candidate where its technical properties match the repair requirement.
ABRO Grey 999® for Japanese Vehicles
Kenya has a large number of Japanese vehicles on the road.
Common brands include Toyota, Nissan, Mazda, Subaru, Honda, Mitsubishi and Suzuki.
These vehicles have different engine designs and service requirements.
Therefore, avoid the mistake of saying:
"This is for Japanese cars, so it works everywhere on every Japanese engine."
That is not technically correct.
ABRO Grey 999® is designed for import-engine applications, but each specific repair must still follow the vehicle manufacturer's requirements.
The right question is:
Does this component and repair procedure require or permit this type of RTV silicone gasket maker?
If yes, Grey 999® may be the appropriate solution.
ABRO Grey 999® for European Vehicles
The same principle applies to European vehicles.
Engine and transmission systems may have specific requirements regarding:
- Gasket material
- Sealant chemistry
- Fluid compatibility
- Application thickness
- Torque procedures
Do not apply RTV silicone to a European engine simply because it is a premium product.
Technical compatibility comes first.
Where a grey, neutral-cure, high-temperature RTV silicone is appropriate, ABRO Grey 999® provides a professional option.
Is ABRO Grey 999® the Same as Ordinary Grey Silicone?
No.
The product should not be confused with general-purpose grey silicone sealants.
ABRO positions Grey 999® as a high-performance automotive gasket maker with properties designed for demanding engine applications.
Its key characteristics include:
Feature ABRO Grey 999®

ABRO Grey 999® vs Other ABRO Gasket Makers
ABRO manufactures several gasket-making products.
Choosing the correct one depends on the application.
For example, ABRO's standard RTV silicone gasket maker range includes products designed for general automotive gasketing, while its Red RTV and Ultra Plus ranges are positioned for different temperature and performance requirements.
Grey 999® is specifically positioned for:
- Import engines
- Precision automotive applications
- Sensor-safe sealing
- High-temperature applications up to its rated limit
- Flexible gasket formation
The best product is not necessarily the most expensive or the highest-temperature option.
The best product is the one that matches the application.
ABRO Grey 999® vs Pre-Cut Gaskets
This is another area where customers need to be careful.
RTV silicone gasket makers can create form-in-place gaskets.
However, that does not mean they should replace every factory gasket.
Some components require:
- Specific rubber gaskets
- Multi-layer steel gaskets
- O-rings
- Composite gaskets
- Manufacturer-approved sealant
In certain applications, RTV is used only as an additional sealant at specific points.
Never assume that removing the original gasket and applying Grey 999® is the correct repair.
Always check the service procedure.
