Product Details

The Cometic C4319-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for the Nissan RB26DETT engine. This gasket features an 86mm bore diameter and a compressed thickness of .040 inches (1.02mm), making it ideal for performance builds and boosted applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability
  • 86mm bore diameter precisely sized for RB26DETT applications
  • .040" compressed thickness for optimal compression ratio tuning
  • Engineered to withstand extreme cylinder pressures in high-performance and forced induction setups
  • Coated with a Viton rubber coating to enhance sealing and prevent leaks
  • Designed to accommodate thermal expansion and engine movement

Cometic MLS gaskets are constructed from multiple layers of stainless steel, providing exceptional resistance to blowout and ensuring reliable sealing even under high boost and extreme combustion pressures. The advanced design allows the gasket to recover and maintain seal integrity through repeated heat cycles, making it the preferred choice for racing and high-performance street applications on the legendary Nissan RB26DETT twin-turbo inline-six engine.
