Product Introduction
3M™ Ultrapro™ High Temp Black Silicone Gasket is a rapid-curing, form-in-place silicone gasket adhesive and sealant developed for the demanding environment of automobile engines. This flexible, non-corrosive compound acts as a cost-effective alternative to hard or custom gaskets, withstanding intermittent engine heat up to 600°F (301°C). It effectively resists oil, water, and ethylene glycol and is oxygen sensor safe, ensuring a durable, long-lasting seal. Easy to apply, it allows for immediate reassembly of engine parts and can be started within 15 minutes, increasing shop efficiency.
