PERMATEX ULTRA GREY RTV SILICONE GASKET MAKER CARTRIDGE 13 OZ

Permatex Ultra Grey RTV Silicone Gasket Maker comes in a 13 oz cartridge, making it a solid option for creating custom gaskets or replacing old ones. This is a popular choice for mechanics and DIYers alike when a specific gasket isn't available or when you need a reliable seal for a variety of engine and transmission components. Its unique formulation is designed to form a durable, flexible seal that can withstand high temperatures and common automotive fluids.

The Ultra Grey formulation is known for its excellent oil resistance, making it particularly well-suited for oil pan gaskets, valve covers, and other areas where oil contact is expected. It cures to a tough rubber that resists vibration and thermal cycling, ensuring a long-lasting seal. Because it's a silicone-based RTV, it adheres well to most surfaces, including metal, plastic, and glass, and it remains flexible after curing, which helps prevent leaks caused by engine movement or vibration.
