## 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
