Hayward SPX2300Z4 Strainer Cover O-Ring

What This Part Is Used For
The Hayward SPX2300Z4 is a strainer cover O-ring for compatible MaxFlo pump models. It seals the pump lid to the strainer housing to maintain a proper vacuum. This gasket sits between the clear lid and pump body.

Why This Part Matters
A worn O-ring allows air to enter the suction side of the pump. Air leaks can cause priming issues, bubbles in returns, and reduced circulation. Replacing the O-ring restores an airtight seal.
