I have a Aquatools AT8230 filter. I need a new O-Ring. My manual lists the Part # 27001-0060. Do you know if this is a suitable replacement? Thanks.

A  Answered on 6/25/2019 by InyoPools Product Specialist Kevin G.

If your filter was installed before March of 1977, then part 4686-22 will be the correct one for you.

?     Asked on 6/7/2016by Chuck

I bought my filter used years ago. How can I tell if it's pre or post 1997? Thanks!

A  Answered on 6/7/2016 by InyoPools Product Specialist Brian M.

Good day. I spoke to a technician at Pentair ( who now ownes Sta-Rite ) and one of the older Sta-Rite techs and he said that the Pre 97 o-ring is thicker than the Post-97. His suggestion was to purchase the Post-97 and, if need be, just add extra lube to complete the seal. Unfortunately, there is no other difference in the tank configuration to tell the time period, other that the sticker with either the pump model or the serial number. Pentair would be able to then tell you the year of the filter tank. If you can find either of those, please give Pentair a call at 800-831-7133.

Is this the correct replacement o-ring for Model AT8230?

A  Answered on 5/22/2016 by InyoPools Product Specialist Patrick P.

Hi Jim, Yes this is the correct replacement o-ring for the Aqua Tools Model AT8230

The cord ring I have is a little stretched out. Is there a way to shrink it a little? It's been fine until this year

A  Answered on 5/5/2016 by InyoPools Product Specialist Charlie R.

James,No, unfortunately due to wear and tear, once an o-ring stretches out, you can't shrink it back to the original size.

Will this fit a PLDE 48 . Did not see it listed . Thanks

How do I know this is the right size? Returnable?

A  Answered on 6/7/2015 by InyoPools Product Specialist Patrick P.

Hi Tim, Yes this item is returnable. Your filter should have a label on the side and if it says PLM 100, 125, 150, 175, 200, 300 or PLD50 or PLD70 then this is the correct o-ring for you. The o-ring on this page was for these models of filters from 1997 to current, if your filter is before 1997 then you would require the 27001-0060S o-ring.
