Characteristics
This 85g grey silicone gasket maker is a high-performance RTV (Room Temperature Vulcanizing) sealant specifically formulated for automatic transmission systems.
It exhibits excellent oil resistance, withstanding the harsh conditions of automatic transmission fluids (ATF) to maintain a reliable seal over extended periods. The
grey silicone material offers good temperature tolerance, typically resisting heat up to 300°F (149°C) or higher (depending on specific formulation) and cold
temperatures without cracking or losing flexibility. It cures at room temperature into a durable, flexible gasket that conforms to irregular surfaces, filling gaps up to
1/8 inch (3mm) to prevent fluid leakage. Additionally, it provides strong adhesion to common automotive metals (such as aluminum, steel) and plastic components
in transmission systems, while remaining resistant to aging, oxidation, and environmental contaminants like moisture and dust.
Features
- Precise 85g Packaging: Ideal for small to medium-sized transmission gasket repairs or replacements, reducing waste and ensuring easy storage.
- ATF Compatibility: Engineered to resist degradation from automatic transmission fluids, avoiding swelling, hardening, or breakdown that leads to leaks.
- RTV Self-Curing: Eliminates the need for heat curing, enabling convenient on-site or workshop application with typical full cure times of 24 hours at room temperature.
- Flexible Cure: Maintains elasticity after curing, accommodating thermal expansion and vibration in transmission systems to prevent gasket failure.
- Grey Color: Matches common OEM transmission component colors, providing a professional, factory-like finish.


Applications
- Sealing automatic transmission pan gaskets: Replaces traditional paper or rubber gaskets for a more reliable, leak-proof seal.
- Repairing transmission housing joints: Sealing gaps between transmission case halves, end covers, or sensor mounts.
- Sealing transmission cooler lines: Securing connections between transmission coolers and fluid lines to prevent ATF leakage.
- Aftermarket or DIY transmission maintenance: Suitable for home mechanics and professional repair shops working on passenger cars, light trucks, and SUVs with automatic transmissions.
- Emergency gasket replacement: Provides a temporary or permanent solution when original gaskets are damaged or unavailable.
