It creates a seal between two engine surfaces, preventing oil or other fluid leaks at the mounting point. Cummins specifies its primary use on non-certified 11-liter M11 engines; you can also find them on L10, ISM, and QSM engines.
Exact compatibility must be verified using the ESN, as the location and configuration may vary.
It is located between the cylinder head and the exhaust manifold; it prevents exhaust gases from escaping.
Cummins specifies the primary use for 10-liter L10 engines; aftermarket catalogs extend the application to the M11, ISM, and QSM families. Final compatibility should be verified using the engine’s serial number.
It is recommended for use in the lubricating oil cooler area of 11-liter Cummins M11 engines, particularly non-certified automotive versions. Normally, two engine gaskets are required when assembling the oil cooler.
The official Cummins website primarily lists it for the M11, but specialized catalogs also confirm compatibility with the L10, ISM, and QSM.
