Description

Multi-Layer Steel (MLS) head gaskets contain load-controlled embossments which conform load distribution across sealing the area. This creates an exceptional seal by requiring less clamp load resulting in less bore distortion.

The stainless steel outer layers are coated with FKM (Viton), a high temperature/chemical resistant polymer. A topcoat of PTFE (Teflon) aids in resistance to fret and increased cold sealing.
