This is a genuine Cummins exhaust manifold seal, designed to seal the connection between the exhaust manifold and the cylinder head.
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 high-temperature exhaust gases from leaking, which can cause loud noise, loss of turbo boost pressure, and potential engine damage. Typically replaced whenever the exhaust manifold is removed for service or if an exhaust leak is detected.
