This is a heavy-duty rubber O-ring designed to seal the water manifold or oil cooler connections on Cummins N14 diesel engines.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It prevents coolant or oil from leaking at the joint between the manifold and the engine block. Over time, heat and pressure can cause the original O-ring to harden, crack, and fail, leading to drips or loss of fluid. Replacing it with this direct aftermarket equivalent (PAI 121229, matching Cummins part 3050667) restores a reliable seal and helps avoid overheating or low oil pressure conditions.
