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.
Gasket Volume +9.4cc
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.
