Red RTV silicone gasketing material designed for use in high temperature mechanical assemblies Great for oil pans, valve covers, exhaust manifolds, differential covers and more Temperature resistant up to 650 degrees Fahrenheit Sets in 1 hour and will not shrink or crack J-B Weld is proudly made in the USA J-B Weld Hi-Temp Red Silicone Gasket Maker and Sealant is an RTV (Room Temperature Vulcanized) Silicone gasketing material, designed for use in mechanical assemblies where the existence of higher, continuous temperatures up to 550 degrees F or 650 degrees F 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. Great for: Oil Pans Valve Covers Exhaust Manifolds Water Pumps Timing Covers Differential Covers Drive Housings Oven Doors Use on: Automotive Metal And more Instructions 1. Prepare:Clean surface area of dirt, grease, oil, paint or loose debris. For best results use a detergent or degreaser to first clean the surface, then roughen surface with file or coarse sandpaper to provide the best repair. 2. Apply: Apply even, continuous _ inch bead of Silicone to one surface area. Surround all bolt holes with Silicone. 3. Assemble: Reconnect parts while Silicone is wet. 4. Secure: Hand tighten until Silicone begins to squeeze out. 5. Dry: Allow drying for 1 hour and then tighten an additional 1/2 turn. 6. Finish: Scrape or cut away excess cured sealant.
