About Cometic Gasket

Cometic Gasket is the world leader in custom multi-layer steel head gaskets for performance and motorsport engines. From off-the-shelf MLS for popular platforms to bespoke gaskets for race-only builds, Cometic seals everything from Honda B-series to LSX.

High-Performance MLS Head Gasket for Nissan RB26

The Cometic Multi-Layer Steel (MLS) Head Gasket is the ultimate sealing solution for your Nissan RB26 engine. With a compressed thickness of 0.051 inches and an 86mm bore, this gasket is precision-engineered to meet the rigorous demands of high-output engines. Its multi-layer stainless steel construction provides the necessary strength to maintain a seal under extreme boost and high-RPM conditions, ensuring your engine performs at its best every time you hit the track.

Technical Advantages

  • Compressed Thickness: 0.051 inch
  • Bore Size: 86mm
  • Construction: Multiple layers of stainless steel
  • Coating: Viton fluoroelastomer for superior sealing
  • Compatibility: Aluminum heads to cast iron or aluminum blocks

The gasket's outer layers are embossed and coated with Viton, a high-heat-resistant rubber material capable of withstanding temperatures up to 482°F (250°C). This coating ensures a leak-free seal even on surfaces that are not perfectly smooth, eliminating the need for additional sealants. The MLS design also allows for slight movement between the cylinder head and block caused by thermal expansion, effectively preventing the gasket from blowing under high cylinder pressures. Whether you are building a stock-replacement engine or a high-horsepower race build, this Cometic gasket offers the reliability and peace of mind you need. Don't compromise on your engine's internal integrity; choose the best sealing technology available. Find your high-performance engine components at GGCRACING.
