Cometic MLS head gasket for Nissan RB25DE/RB25DET engines uses multi-layer stainless steel construction with embossed outer layers coated in Viton to handle harsh sealing environments. This .027" gasket is specified for an 87mm bore and offers a compressed operating thickness of 0.036". The center shim layer is uncoated stainless steel for thickness control; the MLS design provides rebound, corrosion resistance, and improved sealing without the need for sealants.
