Cometic Gasket

Does the head need to stay sealed as cylinder pressure rises? Cometic Gasket makes gaskets for engine builders and tuners who want to be sure their engine seals under high load. Here you’ll find MLS head gaskets, gasket kits and individual gaskets for a wide range of car and motorcycle engines.

American gaskets for hard-working engines

Cometic Gasket is an American manufacturer from Ohio that has become a well-known name among engine builders in both the car world and powersports. The brand is especially known for multi-layer steel head gaskets, also called MLS. When an engine gets a turbo, supercharger or higher compression, cylinder pressure rises sharply, and that is where a factory gasket often falls short. Cometic makes its gaskets with precise machining and offers them in many thicknesses and bore sizes, so they suit both stock and built engines.

Cometic Gasket’s key products

MLS head gaskets are the core of the range. They consist of several steel layers with a coating that seals against the head and block and withstands high temperatures and pressures. Because the gaskets come in several thicknesses, you can also use them to fine-tune the compression ratio. Besides head gaskets, Cometic offers complete gasket kits for engine rebuilds as well as gaskets for exhaust, valve covers, oil pans and other parts of the engine. The range also covers a wide range of motorcycles, ATVs and other powersports vehicles.

Frequently asked questions

Why choose an MLS head gasket?

A multi-layer steel gasket handles higher cylinder pressures and temperatures than many factory gaskets. That makes it an obvious choice for turbocharged, supercharged or high-compression engines.

How do I choose the right thickness?

Thickness affects the compression ratio and the piston-to-head clearance. Normally choose the thickness that suits your pistons and engine build, and ask your engine builder or us if you are unsure.
