## Description

Captain O-Ring - Replacement 151122 O-Rings Compatible with Pentair Pentek Big Blue Water Filters OEM Size ORing Buna-N (3 Pack) : desertcart.ae: Kitchen

Review: These o-rings fit the Pentair Big Blue filter much better than other brands I have bought. Other brands had a diameter slightly too big for the o-ring channel in the filter sump, making it difficult to seat them in the channel, which required multiple attempts to reattach the sump to the top of the filter to get the assembly leaktight. These o-rings were just right. They seated totally within and against the outside wall of the filter sump o-ring channel, so when the sump was reattached to the top the filter it was leaktight on the first try.
Review: Good fitment. Seems to be good quality rubber. No leaks!

## Questions & Answers

**Q: can this ring be streching?**
A: Do you mean can it be stretched?  Essentially, no.  A little bit, but O-rings are not elastic like rubber bands.

**Q: Anyone tried these on us water systems magna (grey housing) filters?**
A: It's plumbing.  There's no way to know whether a gasket or part will fit without buying it and trying it.

**Q: is this the o ring for an Aqua Flow 26258?**
A: The filter housing for this ring is for a 20" Big Blue filter which was installed by Culligan......my guess is the diameter is a standard size for any 20" housing.....but best to confirm with Aqua Flow

**Q: Will these fit the eco pure epw4 filter**
A: i dont believe so
