Updated 06/25/2026 | Published 06/21/2026
Question:
Hello! Im looking for o-rings to replace the ones in my sewer caps. Do you sell just those o-rings or do I need to purchase the entire cap? Thanks!

Hey David, we don't have a way to get just the o-rings from the Camco caps so you would need to order a new cap with the part # CAM39452. How long did your o-ring last?

I had the same problem and purchased the cap as the easiest fix and it has worked fine. I also purchased some extra o rings from RV store to have backups in the future.

Hello - I had similar problem over a year ago.....lost the O-ring on the original cap. Did a bit of looking around in plumbing sections at Home Depot, Lowes and determined for a few dollars ($5 or so) it's just easier to replace the cap rather than spend time and expense trying to find a replacement O-ring. If you are determined, suggest contacting a plumbing supply house or spend time with Amazon plumbing suppliers.
