Product details

The Sta-Rite C20-46 is the adapter gasket for the D Series commercial pumps. It is a round cardboard gasket with 8 holes.

The measurements

9-1/2 in across the outside, 8 in across the inside and 1/16 in thick. The 8 holes are 7/16 in in diameter, spaced 8-7/8 in center to center from one hole to the one opposite it. Those figures are worth checking against the old gasket, because commercial pump gaskets look alike and do not interchange.

Why it is worth replacing properly

A gasket is a small part sitting in an expensive joint. Reusing a compressed or torn one to save a service visit is what turns a weep into a flooded pump room. When the adapter comes apart for any reason, this is the part that goes back in new.

Questions and answers

What people ask about this product, answered by our pool techs.

What are the exact dimensions?
9-1/2 in outside diameter, 8 in inside diameter and 1/16 in thick, with 8 holes of 7/16 in, spaced 8-7/8 in center to center to the opposite hole.
Which pumps does it fit?
The Sta-Rite D Series commercial pumps, the DMH, DMJ, DHH and DHJ models.
What is the gasket made of?
Cardboard. That is the original material for this adapter joint, not a rubber or paper substitute.
Can I cut my own?
You can, but the hole pattern has to be right or the joint pulls unevenly and weeps. The measurements above are what a substitute has to match.
