I have an older model Dura-Glas H/L series, model P2RA5YF-125
hot tub pump. The old gasket has pretty much disintegrated but it appears to cover only the perimeter (including, of course, the screw holes) and not right up to the 3” pipe as does the c-20-103-r
Will this one work? (the dimensions seem to be the same otherwise) I’m hopeful the screw holes will align.

Yes, the Gasket, Pot To Volute (c-20-103-r) is correct for the Sta-Rite Dura-Glas and Max-E-Glas pump model that you own.

Is the gasket as well as the drain plug below it on the suction side or pressure side? Thanks!

The gasket worked excellently. The old one was extremely thin. I didn't expect this one to be as thick as it was. IT didn't tell me how think it was when I ordered it. I had a hard time putting it on but was successful with help. It's doing an excellent job and should last me a long, long time. Thank you, Betty Jane S.
