I have a posi flo pool filter model # 100TXR. Im looking for the rubber rings that fit between base and bottom of metal cylinders that hold filters. Not sure of diameter of rubber ring. Does it vary? Are there different sizes or does model number only use one specific size? Thanks so much!! Filters are leaking quite a bit.

For the Sta-Rite filter (posi-flow) model T-70TX , you list the bottom O-Ring WC9-3 which matches my parts spec. but not a top o-ring. My spec diagram show the top O-Ring as part #U9-301. and states they are not interchangeable. My question is will your part #WC9-3 work on both top and bottom of the filter tank ?
I want to order a filter cartridge replacement ( your part # NFC 2540 and both top and bottom O-Rings for the tank. please advise...Thank You...E. Montee

I ordered the top and bottom o rings for a Sta-rite posi flow model PTM100 a 4686-03 top and a 9239-04 bottom. I received two bagged o rings that do not match the numbers I ordered. One is a WC93 Starite o ring (APCO2081 or APCO239) and the second one is APCO2252 (355329 PACFAB o-ring or 0-419) Are these the correct ones and which one is the bottom o-ring?
Thanks
Hi, Ed. Yes, those O-rings are interchangeable.

Pros: easy install
Cons: none
I was happy to find this part because my local pool supplier told me it was no longer available. Now that I found Inyo Pools they are going to lose a lot of my bussiness.

The O-ring was the perfect size for the filter base I bought, too often the pool supply stores do not have the right size and I wind up using a slightly larger o-ring that causes undo stress on the base.
