Hayward SPX3000S Strainer Cover O-Ring - For Super II

What This Part Is Used For
The Hayward SPX3000S is a strainer cover O-ring used on Super II pumps. It seals the lid to the strainer housing so the pump can maintain prime and proper suction. This O-ring is located in the lid groove at the front of the pump.

Why This Part Matters
If the O-ring is flattened, cracked, or missing, the pump can pull air and lose prime. That leads to noisy operation, weak flow, and inconsistent filter pressure. Replacing the correct Super II lid O-ring restores airtight suction and reliable circulation.
