Cometic Cummins 3.9L 4BT Cylinder Head Gasket

The Cometic Cummins 3.9L 4BT cylinder head gasket is a top-tier component designed for high-performance engines. Engineered with precision, this gasket offers superior sealing performance, ensuring a tight seal between the cylinder head and block. Constructed from multiple embossed layers of stainless steel, the outer layers are coated with Viton rubber, providing exceptional durability and resistance to heat and corrosion.
  • Sealing Excellence: Cometic MLS gaskets offer maximum sealing performance, eliminating the need for additional sealants.
  • Material Durability: The combination of stainless steel and Viton rubber ensures the gasket can withstand the harsh conditions of high-output engines.

Key Product Properties and Specifications

This head gasket is tailored for the Cummins 3.9L 4BT engine, with a bore size of 4.100 inches and a maximum compression thickness of 0.098 inches. The outer layers of the gasket are embossed and coated with Viton, a heat-resistant rubber that can withstand temperatures up to 250°C (482°F). The uncoated center layer, made of stainless steel, allows for variable thickness to accommodate different requirements.
