Cometic MSL Head Gaskets

Cometic Gaskets are world wide known with almost all forms of motorsport.

From road replacement to Le'mans Endurance, Supercars, Nascar and nearly everything in between.


MLS multi layer steel head gaskets produced by Cometic are a quality gasket manufactured in the USA and offer a massive selection of applications in various thickness and bore sizes.

Simply construction in a 3 layer gasket features the outer layers coated and embossed on both sides with Viton (a flouroelastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

With today's modern smaller capacity engines developing sizable HP and torque levels, higher cylinder pressures and requirement for more clamp load for head and block, Cometic is the first choice for a performance and race engine head gasket to ensure optimum cylinder seal.


Speedfactor Ltd carries a comprehensive range of head gaskets for popular applications in stock, through to oversize bore fitments and also custom gaskets for specific engine builds for the NZ market.


We have been supplying Cometic gaskets to New Zealand customers for over 12 years and use them on 95% of engines we build.
