The Aladdin O-510 Strainer Cover O-Ring is molded to match the original Hayward SPX4000TS seal used on NorthStar pump strainer lids, providing a precise, reliable replacement that helps maintain strong pump priming. Its chemical-resistant elastomer construction holds flexibility under pressure, heat, and repeated lid removal, creating a consistent suction-side barrier that prevents air intrusion and water leakage. Sized to follow the OEM-style NorthStar lid groove profile, the O-510 seats cleanly for secure closure during routine maintenance. Designed for daily operation in demanding pool environments, it supports efficient water flow, stable suction, and dependable pump performance.
