Pentek 151122 O-ring (OR-100) is used for "Big Blue" Housings by Culligan, Ametek, Ace Hardware, Pentek, US Filter, Plymouth, Kleen Plus, and American Plumber.

An O-Ring is very important part of your water filter system, and it should be maintained and replaced regularly. The O-Ring serves as a gasket to seal the housing sump to the housing cap to prevent leaks.
Important O-Ring Tips:
- Inspect O-Ring during each filter change for damage, cracks, splits
- Cover O-Ring with silicon lubricant during each filter change
- Do not overtighten filter sump (do not use filter wrench to tighten sump - only use wrench to loosen sump)
- Repace O-Ring every two filter changes
