Construction & Design:

The MLS-5 Head Gasket features a multi-layer steel construction, combining three to five layers of stainless steel to provide exceptional strength and flexibility. Stainless steel is chosen for its ability to resist corrosion and maintain structural integrity under thermal cycling and mechanical stress. The gasket’s embossed outer layers are coated on both sides with Viton rubber, a fluorocarbon elastomer known for its excellent heat resistance and chemical stability.

This Viton coating enhances the gasket’s sealing capability by conforming to surface irregularities and preventing leaks caused by combustion gases or coolant. The gasket thickness of 0.051 inches ensures proper compression and fitment within the cylinder head assembly, maintaining engine performance and reliability.
