J-B Weld Ultimate Copper Silicone Gasket Maker and Sealant is an RTV (Room Temperature Vulcanized) Silicone gasketing material that is 3 times more oil resistant than conventional silicones and designed to resist the high operating temperatures of turbocharged or high-performance engines. Ultimate Copper is effective in temperatures from -75F to 700F intermittent. Upon curing, which occurs when the product is exposed to the moisture in air, the silicone forms a tough, waterproof seal on most surfaces. It will not shrink or crack, resists weathering, is sensor safe and is great for many automotive applications.
