Sir: May I inquire if this clamp be suitable for a twenty five ( 25) year old STA-RITE 1 Hp pool pump with Dura-glass cover? The nameplate was damaged beyond recognition but it was bought new when installed. Best regards, Bob Manila, Philippines:

Will this clamp fit on a Pantera filter model number P24?

A  Answered on 9/13/2016 by InyoPools Product Specialist Lennox H.

Hi Gisele, No. This clamp will not fit the Pantera Sand Filter Mo. P24. The part number for the clamp Assembly is p/n 24201-0103 which we do not currently have.

I have a Pentair P2R pump and need just the tee bolt and nuts for the Tank Body Clamp. Is it available as a separate part?

A  Answered on 10/8/2018 by InyoPools Product Specialist Lennox H.

Hi, Jim B. Unfortunately, the Tee Bolt is not available as a separate part.  The Knob - WC36-22-50 is the replacement knob for the clamp.

I am looking for the clamp that fits a Flow Master DE filter by Anthony Pools that has model number 57025800 (54 sq. Ft.). It has a hexagonal nut and heavy duty spring to tighten the clamp. I’m pretty sure this is not the correct one but, if not, you may know the correct one. In the manual it has a part number 55029300. Many Thx.

Unfortunately, the clamp for the Flow Master DE filter is obsolete.  They no longer make that clamp.

Hi The model no. on my seal plate says P2RA5E-18(1 or an L) L. In the parenthesis I put a 1 or an L, because it was hard to read on the name plate. Is this the correct replacement clamp for my Seal Plate ? Also is the 10" O ring part# 5056-06 the correct one for my seal plate?


A  Answered on 8/19/2021 by InyoPools Product Specialist Craig C.

Hello Randy.   Tank Body Clamp C119-37S s the correct replacement clamp for the Pentair Dura-Glas Pool Pump.  Seal Plate O-ring 5056-06 is the correct seal plate o-ring for the Pentair Dura-Glas Pool Pump.  Attached please find an exploded parts diagram for the Pentair Dura-Glas Pool Pump as reference.   Sta-Rite Dura-Glas and Max-E-Glas
