Permatex Ultra Black is an RTV (room temperature vulcanizing) silicone that forms a flexible, durable gasket in place of a cut gasket, sealing instantly on contact and curing at room temperature. The formula is built for maximum oil resistance, making it a good choice for engine, generator, and equipment gasket work.
Comes in a cartridge format rather than a squeeze tube, so it's suited to larger repair jobs or shop use.
