This O-Ring Plug fits Cummins and Mack cab and chassis applications and is built as a replacement for the OEM sealing plug. It ships as a kit containing a separate plug and O-ring, one of each, sold as a single unit. The threaded head compresses the O-ring against an unused port or drilled passage to block fluid or air leakage without needing sealant.
