?     Asked on 9/1/2015by Maria

I have an American Products Predator Cellular Media pool filter. It never had an O-ring. I can't find the correct size anywhere. The serial number of filter is 017875. and model media # 56408100 / filtration area 75 sq. ft./ replacement part no. 59054100. I would appreciate assistance in finding the correct size for this locking O-ring. Thank you in advance.

Hi Maria, The Predator/Clean and Clear Tank O-ring (447) would be the correct tank o-ring for your filter.

I have a AV60 is this the right o-ring for between the filter and pump?

Garry, part number 4800-27 is the o-ring used on various pool filters, not necessarily the pump.

I have an old Purex 4000 Series Molded D.E. pool filter and it is leaking on the top where the pressure gauge is. Does this O-ring fit under the gauge to help keep it from leaking or is there some other type of seal replacement for it?

A  Answered on 9/20/2018 by InyoPools Product Specialist Lennox H.

Hi, LB. This o-ring will not fit under the pressure gauge. There is no o-ring that is placed under the pressure gauge for the Purex 4000 Series Filter. Check out the Purex 4000 Series Molded D.E.

Hi, Tony. You can replace the Collar O-ring by removing the grid assembly and manifold. without removing the valve.
