Hayward LATCH FOR LOCK RING

the Hayward O-Ring Kit (Set of 2) is a specialized maintenance package containing critical sealing gaskets designed to restore or maintain the watertight integrity of various connections within a pool’s filtration and plumbing system. These O-rings are typically manufactured from a high-performance, chemical-resistant synthetic elastomer, engineered to resist the drying and cracking caused by constant exposure to UV rays, salt-water sanitization, and concentrated chlorine. Their primary mechanical function is to provide a compressed, vacuum-tight seal at connection points—such as union adapters, pump housings, or valve interfaces—preventing pressurized leaks and ensuring the system maintains a consistent hydraulic prime. By replacing both gaskets simultaneously as a matched set, pool owners can ensure uniform tension and seal reliability across dual-connection points, which is essential for the smooth, air-free operation of the circulation loop. For shipping and logistical purposes, the estimated weight of the Hayward O-Ring Kit (Set of 2) is approximately 0.15 pounds in its retail protective packaging, while the actual dry weight of the two rubber rings combined is roughly 0.06 pounds.
