CumminsSealing O-Ring Cummins Engine ISC – Engine QSC
O-Ring Seal Cummins Engine ISC 8.3 – Engine QSC 8.3
It is located between the oil pump and its housing or fitting, providing a static seal between mating components and preventing leaks of oil or other fluids in the circuit where it is installed. It also appears in the section on the lubricating oil system/oil pump, but the exact location may vary depending on the CPL and configuration.
Observed on 6C 8.3 / 6CT / 6CTA, ISC 8.3, QSC 8.3, ISL 8.9/9, QSL 8.9/9, QSB 6.7, and ISB 6.7 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.

CumminsSealing O-Ring Cummins Engine ISC – Engine QSC
O-Ring Seal Cummins Engine ISC 8.3 – Engine QSC 8.3
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.

CumminsSealing O-Ring Cummins Engine ISC – Engine QSC
O-Ring Seal Cummins Engine ISC 8.3 – Engine QSC 8.3
Used primarily in the fuel pump system, at the point where the pump connects to its housing or mounting surface, Cummins officially specifies it primarily for 8.9-liter ISC/ISL Tier 3 engines. It creates a seal between the mating surfaces of the fuel pump system, preventing leaks and maintaining proper circuit integrity. Made of Viton/FKM, 75 durometer, a material resistant to fuels, oils, and high temperatures.
Observed on 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9, ISL9 e QSL 8.9 engines.
Before selling or installing an engine, I always recommend verifying the engine’s ESN and CPL, either using Cummins QuickServe or the OEM catalog, or by checking the original number that was removed. The C/ISC/QSC/ISL/QSL family includes numerous revisions to the fuel system, and a cross-reference may only be valid for certain CPLs or configurations.

CumminsRear Crankshaft Seal Kit Cummins Engine ISB 4.5
Rear Main Seal Kit Cummins Engine ISB 4.5
The kit provides a seal at the rear of the crankshaft, preventing engine oil from leaking at the point where the crankshaft exits the engine block toward the flywheel/transmission housing. It is therefore installed at the rear of the engine block, on the flywheel side. The sealing component is typically made of a technical elastomer that is resistant to oil and high temperatures, combined with metal support/reinforcement elements.
Compatible engines: 4B, 4BT, 6B, 6BT, 6C, 6CT, 6CTA, ISB, QSB, ISC, QSC, ISL, QSL
However, we recommend checking the ESN/CPL before the sale: not all configurations within the same engine family necessarily use the same oil seal.
