JB Weld Hi-Temp Gasket Maker & Sealant
  • JB Weld Hi-Temp Gasket Maker & Sealant

    RTV (Room Temperature Vulcanized) Silicone gasketing material, designed for use in mechanical assemblies where the existence of higher, continuous temperatures up to 550F or 650F intermittent might exist. 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.
