K2 B250N Liquid Silicone Grey, 85g

K2 Gray Silicone 85G. This high-quality, high-temperature gray silicone sealant is designed to perfectly adapt to sealed surfaces and withstand extreme temperatures up to +350°C. Meeting Original Equipment Manufacturer (O.E.M.) standards, it effectively replaces traditional gaskets made of cork, paper, felt, asbestos, and rubber.

Formulated with a Sensor Safe technology, it is completely safe for lambda sensors in modern electronic fuel injection vehicles and offers strong resistance to oils, greases, and coolants. It is ideal for sealing valve covers, thermostat gaskets, oil pans, camshaft covers, water pumps, rear axle covers, and other automotive components across all car models and brands.

To use, ensure the surface is clean, dry, and free of old sealant. Apply a small amount of silicone, smooth or remove excess with a soap-dipped tool, and allow it to dry—it begins to dry after 5 minutes, is touch-resistant after 1 hour, and fully cures in 24 hours.
