Keep automotive components securely sealed with this Black Hi-Temp RTV Silicone Gasket Maker & Sealant. Designed for demanding automotive applications, this RTV silicone cures at room temperature to form a flexible, durable rubber-like seal that helps protect against leaks caused by vibration, temperature changes, and thermal cycling.
Ideal for use on a variety of automotive sealing applications, including valve covers, oil pans, timing covers, water pumps, thermostat housings, and differential covers.
High-Temperature RTV Silicone: Designed for continuous operating temperatures up to 260°C (500°F) and intermittent temperatures up to 315°C (600°F).
Oil & Fluid Resistant: Helps resist exposure to engine oil, transmission fluid, gear lube, coolant, and water.
Flexible & Durable: Forms a flexible rubber seal that accommodates normal engine vibration and thermal expansion.
Non-Corrosive Formula: Designed for automotive sealing applications where a non-corrosive RTV silicone is preferred.
Versatile Automotive Use: Suitable for many engine and drivetrain sealing applications.
Helps Prevent Leaks: Creates a continuous seal between properly prepared mating surfaces.
Black Finish: Suitable for applications where a black RTV gasket maker is required.

Remove the old gasket material and thoroughly clean the mating surfaces.
Ensure all surfaces are clean, dry, and free from oil, grease, dirt, and residue.
Apply a continuous 2–3 mm bead of RTV silicone around the sealing surface and bolt holes where required.
Reassemble the components while the silicone is still wet, preferably within approximately 10 minutes.
Allow the sealant to cure for approximately 24 hours before exposing the sealed joint to pressure or service conditions.
Always follow the vehicle or component manufacturer's recommended gasket and sealant specifications.
Surface preparation is essential for proper adhesion and sealing performance.
Cure time may vary depending on temperature, humidity, bead thickness, and application conditions.
Do not use the product for applications outside its intended temperature, chemical, or mechanical limits.
Check compatibility with the specific vehicle component before installation.
