Cummins describes this part as a "noise isolator" and it replaces the original O-ring that came on the factory-original bolt. This noise isolator mounts inside the valve cover and serves the same function as the original O-ring while also helping reduce valve train noise.
*Sold individually. 6 are needed for a complete job.
