Sealing O-Ring Cummins Engine ISL – Engine QSL
O-Ring Seal Cummins Engine ISL 8.9 – Engine QSL 8.9
It seals the joint between mated components, preventing fluid leaks and maintaining circuit pressure. It is installed in a circular seat between two mated components of the fuel system, where it creates a seal that prevents diesel leaks and pressure loss. It is not an external engine block gasket. Some sources refer to this family of seals as Fuel Shaft O-Rings, so the application may be associated with the shaft/fuel system circuit area.
Observed on 6C 8.3 6CT 6CTA, ISC 8.3, QSC 8.3, ISL 8.9, QSL 8.9 engines.
We always recommend checking the ESN and CPL in the Cummins OEM catalog, because the same O-ring is used across different engine families, and the quantity and location may vary depending on the engine configuration.
