Pentair U9-226 O-Ring Diffuser Replacement for select Sta-Rite Pool and Spa Filters

Just what was needed to replace worn part.

Genuine Pentair. I used this to fix a leak on my spa heater where the PVC pipe connects.

Replaced the diffuser O-ring on my pool pump. No leaks. Awesome.

Was exactly the o-ring needed for my Maxiglass diffuser. Delivered in 3 days.

If you're looking for the O-ring to replace for a Pentair Mastertemp pool heater for either the in/outlet this doesn't fit. it is too small and isn't a match.

Tough to get in there but perfect replacement

great

This fit perfectly on my old pump... about four months and not a single drop of water has leaked.
