Hayward Strainer Cover O-Ring | SPX2300Z4 Pool Deck Hardware Replacing the correct dome restoresWhat 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.
