Hayward O-RING, SET OF 2 FOR GAUGE ADAPTER/AIR RELIEF

The Hayward O‑Ring Set of 2 for Gauge Adapter/Air Relief includes two small sealing gaskets designed to maintain a tight, leak‑free connection around the pressure gauge adapter or air‑relief assembly on compatible Hayward filter systems. These O‑rings help prevent air intrusion and water seepage, ensuring accurate pressure readings and stable system performance. Their flexible, chemical‑resistant material allows them to compress evenly under pressure and endure repeated tightening, vibration, and long‑term exposure to treated water without hardening or cracking. Because they are compact rubber components, the estimated combined weight generally falls in the range of 0.01 to 0.03 pounds.
