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.

Premium MLS Head Gasket for Nissan RB25

Achieve maximum sealing performance in your high-output Nissan RB25 engine with the Cometic Multi-Layer Steel (MLS) Head Gasket. Engineered for precision, this gasket features a compressed thickness of 0.051 inches and an 87mm bore, specifically designed to handle the extreme pressures and temperatures of modified engines. By utilizing multiple layers of stainless steel, this gasket provides superior rebound and corrosion resistance, ensuring a perfect seal between your block and cylinder head.

Key Features and Benefits

  • Compressed Thickness: 0.051 inch
  • Bore Size: 87mm
  • Material: Multi-Layer Stainless Steel with Viton coating
  • Heat Resistance: Up to 482°F (250°C)
  • No Sealant Required: Designed for a clean, dry installation

The outer layers are embossed and coated on both sides with Viton, a high-performance fluoroelastomer rubber that excels in heat resistance and sealing integrity. This design is perfect for both aluminum-to-aluminum and aluminum-to-cast-iron engine combinations, effectively managing the shearing forces caused by differing thermal expansion rates. Whether you are building a street-driven performance machine or a dedicated track car, the Cometic MLS gasket is the industry standard for preventing leaks and maintaining consistent compression. Its robust construction ensures that it can withstand the rigors of forced induction and high-RPM operation. Upgrade your engine build with the reliability of Cometic Gasket technology found here at GGCRACING.
