Standpipe to Cooler/Adapter O-Ring

This factory Cummins O-ring is used for the EGR cooler to coolant standpipe connection.


  • Good morning. Just wondering if it is a difficult job to replace the o-ring on the stand pipe to egr cooler adapter? Does the stand pipe have to be completely removed? Or is there enough flex in the braided section to allow enough room to slide it out and back together? I’m new to the emissions era diesel engines. Don’t want to bite off more than I can chew.
