Hayward Strainer Cover O-Ring | SPX3000SV Pool Filter Cartridges Upgrade your spa today withWhat This Part Is Used For The Hayward SPX3000SV is a strainer cover O ring used to seal the pump lid to the strainer housing on compatible Hayward pumps. It sits in the lid groove and prevents air and water leaks during operation. This O ring is a routine maintenance item. Why This Part Matters A dry, flattened, or nicked O ring lets air into the pump and can cause loss of prime. That shows up as bubbles in the pump basket and weak return flow.
