Fitment Notice

Confirm fitment by Cummins engine model, component assembly, and original part number before ordering. O-ring seals can look identical but differ by diameter, thickness, and material.

When This Part Needs Replacement

Replace this seal whenever the related component is removed, or if the old O-ring is cut, swollen, flattened, brittle, cracked, or leaking. Reusing old O-rings can lead to seepage after reassembly.

Installation Notes

Clean the seal groove and mating surface before installation. Lightly lubricate the O-ring with the correct service fluid when required, seat it evenly in the groove, and avoid twisting or pinching during assembly.

Parts Desk Insight

With Cummins seals, the safest match is always by exact part number and assembly location. A seal that looks close on the bench may still have the wrong cross-section or material for the job.
