Details

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.

Features:
  • Three times more oil resistant
  • Advanced high temperature RTV sealant adhesive
  • Designed for high operating temperatures

Applications:
  • Oil Pans
  • Valve Covers
  • Exhaust Manifolds
  • Water Pumps
  • Timing Covers
  • Differential Covers
  • Drive Housings
  • Oven Doors

Instructions:
  1. Prepare: For best results, clean and dry surface area.
  2. Apply: Apply even, continuous 1/4 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. Silicone will fully cure in 24 hours
