Pentek O-Ring for Big Blue Filter Housings
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. O-ring is approximately 5 3/4" in diameter. This O-Ring is used in all Big Blue housings by Pentek with 1" NPT and 1-1/2" NPT EXCEPT the Big Clear Housing.
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
Save Your Furnace Tip #3:
Did you know that the nominal size of your air filter is probably not the same as the actual size? Just like measurements on lumber, the actual size of an air filter is usually slightly smaller than the nominal size.
