Granville Instant Gasket is an acetoxy cure silicone sealant that cures quickly to provide a permanently flexible seal, making it ideal for use as a gasket sealant to replace pre-formed gaskets. It is also suitable for use with pre-formed gaskets. This product must not be used on cylinder heads. Benefits include replacing pre-formed gaskets, permanent flexibility, quick curing, and excellent waterproof sealing. To use, remove the cap and pierce the end of the tube. Apply the nozzle and cut cleanly at a 45-degree angle with an opening slightly larger than the gap to be sealed. Best results are achieved by keeping even pressure on the tube and maintaining a constant angle to the surface being sealed. It is resistant to high temperatures, water, transmission fluids, and antifreeze. It is non-shrinking and remains flexible. Suitable for use on agricultural equipment, diesel generators, compressor motors, and hydraulic equipment.
