Watch in action

Superior Sealing with Cometic MLS Technology

Maximize the reliability of your Nissan RB20E, DE, or DET engine with the Cometic Multi-Layer Steel (MLS) head gasket. Designed for high-output performance, this 80mm bore, .051-inch compressed thickness gasket provides a superior seal that stands up to the intense cylinder pressures of forced induction and high-compression builds.

Why Choose Cometic MLS Gaskets?

  • Multi-layer embossed stainless steel construction
  • Viton rubber coating for superior heat resistance (up to 482°F)
  • No additional sealants required for installation
  • Excellent rebound and corrosion resistance
  • Ideal for aluminum heads to cast iron blocks

Cometic gaskets are engineered to handle the shearing forces generated by dissimilar materials, making them the gold standard for engine builders. The outer layers are embossed and coated on both sides with Viton, a high-temperature fluoroelastomer that ensures a leak-free seal even under extreme thermal cycling. Whether you are rebuilding a stock RB20 or pushing the limits of a track-prepped Skyline, this gasket offers the strength and consistency needed to keep your engine running strong. Invest in the best sealing technology for your Nissan build at GGCRACING.
