Product Details

✓Easy-Disassembly RTV Silicone Gasket Maker: Optimum Black combines maximum oil resistance with maximum flexibility
✓Seals Strong, Removes Fast: When it is time to service, loosen the parts and peel the gasket away by hand; no scraping means less downtime on oil pans, timing covers, transmission pans and differential covers
✓Built for Modern Engines: 15% Stronger and 60% more flexible than Ultra Black to handle unlike materials, thinner metals and wider bolt patterns; sensor safe, low odor and non-corrosive for technicians and DIYers
✓Simple Application: Load the cartridge into a standard caulking gun, apply a continuous bead to clean, dry, oil-free flanges, circling all bolt holes, and assemble; resists auto and shop fluids and vibration once cured
✓Trusted by Professionals Since 1909: Permatex has developed chemical solutions for automotive maintenance and repair for more than a century; our thread compounds are formulated to help pros and DIYers get the job done right
