RWA1582-51 is manufactured by Cometic and uses their MLS process. Multi Layer System. Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load–resulting in less bore distortion. The stainless steel outer layers utilizing FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic’s MLS head gaskets, no sealants or re-torque is required.
