Hayward UNION 2.5 KIT (1PC) W/ORING

The Hayward 2.5‑inch Union Kit with O‑ring is designed to create a secure, serviceable connection between large‑diameter pool plumbing and compatible equipment such as pumps, filters, or heaters. The union body provides a sturdy threaded interface that allows components to be disconnected easily for maintenance without cutting pipe, while the included O‑ring forms a reliable, watertight seal that holds up under pressure, vibration, and long‑term exposure to treated water. Its durable, chemical‑resistant construction helps maintain structural integrity and leak‑free performance over time, making it a practical replacement or upgrade component for high‑flow pool systems
