The Cometic MLS head gasket for Nissan RB26DETT (86mm bore) is a multi-layer stainless steel cylinder head gasket with a nominal thickness of .027in and compressed operating specifications in manufacturer notes. It seals high-output RB26 applications without sealants and suits aluminum-to-aluminum or aluminum-to-cast-iron joints. Embossed outer layers are Viton-coated for heat-resistant sealing; the uncoated stainless shim layer allows thickness variation, aids rebound, evens load distribution, and reduces clamp load distortion.
