Hayward ORING 2-232 F/ 2.5" UNION 4PK

The Hayward O‑Ring 2‑232 for 2.5‑inch unions, sold in a four‑pack, is designed to create a reliable, watertight seal in high‑pressure plumbing connections commonly found in pool and spa systems. These O‑rings help prevent leaks at union joints by maintaining consistent compression even under fluctuating temperatures, pump vibration, and long‑term exposure to treated water. Made from durable, chemical‑resistant elastomer material, they retain flexibility and sealing performance over time, making them a practical maintenance item for ensuring smooth, efficient system operation and reducing the likelihood of unexpected leaks or pressure loss.
