Cummins 3924389 Genuine Turbo Oil Feed Line Sealing Washer

The Cummins 3924389 Genuine Turbo Oil Feed Line Copper Sealing Washer will replace the missing or bent washer on the turbocharger in your Dodge 2500/3500 5.9L Diesel. This washer should be replaced when installing a feed line back into the turbocharger, as it gets compressed and should not be reused. This washer is designed to create a tight seal between the turbo oil feed line and the turbocharger once it’s compressed.
