Frequently Asked Questions

What is the difference between an RTV Gasket Maker and a traditional gasket?

RTV (Room Temperature Vulcanizing) Gasket Makers, like Permatex Ultra Copper, are liquid sealants that cure into a durable, flexible rubber seal. They are used to replace or supplement traditional pre-cut gaskets, particularly on components with complex or uneven sealing surfaces (e.g., oil pans, differential covers). Traditional gaskets are pre-formed pieces of material (metal, composite, or rubber) designed for specific mating surfaces.

What does MLS stand for in gaskets?

MLS stands for Multi-Layer Steel. These gaskets are constructed from several layers of embossed steel, providing superior sealing integrity under the high combustion pressures and thermal cycling found in modern and high-performance engines. They are most commonly used for head gaskets.

How do I ensure a proper seal when installing a gasket?

Proper installation requires clean, dry mating surfaces free of old gasket material or oil residue. Always follow the manufacturer’s torque specifications and sequence (especially for head and manifold gaskets) to ensure even pressure distribution. For RTV sealants, allow the recommended cure time before exposing the engine to fluids or heat.
