Construction & Design
The Cometic MLS Cylinder Head Gasket is meticulously crafted from multiple layers of stainless steel, each embossed to enhance sealing performance and durability. The outermost layers are coated with Viton, a premium fluorocarbon elastomer known for its exceptional heat resistance and chemical durability. This coating ensures the gasket maintains a tight seal even under extreme thermal cycling and high-pressure conditions.
The core shim layer is made from uncoated stainless steel, providing structural integrity and allowing for precise thickness adjustments to meet specific engine requirements. This multi-layer design enables the gasket to flex and rebound, accommodating the differential expansion rates between aluminum heads and cast iron or aluminum blocks without compromising the seal.
