Cummins 3693798 Turbocharger Gasket

The Cummins 3693798 is a turbocharger mounting gasket designed to seal the interface between the turbocharger turbine housing and the exhaust manifold on heavy-duty diesel engines. It is constructed from multi-layer steel (MLS) with a molybdenum disulfide (MoS2) coating to withstand extreme thermal cycling and exhaust gas temperatures. This gasket prevents exhaust leaks, maintains turbocharger efficiency, and ensures emissions compliance. It supersedes and interchanges with Cummins part numbers 3685535 and 3695041. Compatible with aftermarket replacements from Interstate-McBee (M-3693798), PAI Industries (131904), and Elring (144.860).
