J-B Weld Ultimate Black Gasket Maker & Sealant is an RTV (Room Temperature Vulcanized) Silicone gasketing material designed for use in mechanical assemblies where maximum petroleum and oil resistance is required. Upon curing, which occurs when the product is exposed to the moisture in air, the silicone forms a tough, waterproof, gasket and seal on most surfaces. It will not shrink or crack, resists oil and petroleum products, resists weathering, is sensor safe, has good temperature resistance up to 500 F intermittent and is great for many automotive applications.

J-B Weld Ultimate Black Silicone is low odour and sensor safe.

Available in 14g or 85g tubes. This product is the 14g tube.
