Product Compatibility
For Cummins applications that specify O-ring seal 145582 by part number in the engine, heat exchanger, cooler, pump, or related component breakdown.
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.
