Hayward ORING VALVE BASE

The Hayward O‑ring for a valve base is designed to create a dependable, watertight seal where the valve body meets its base, helping maintain proper pressure and preventing leaks in pool and spa plumbing systems. Made from durable, chemical‑resistant elastomer material, it retains flexibility and sealing strength even under continuous exposure to treated water, temperature changes, and pump vibration. Its precise sizing ensures a snug fit within the valve assembly, supporting smooth operation and reducing the likelihood of air intrusion or water loss over time.
