Waterway Plastics 415-4000 Union Nut - 1.5 inch White

What This Part Is Used For
The Waterway Plastics 415-4000 union nut is used to secure 1.5 inch plumbing union connections in pool and spa systems. It threads over the union tailpiece to compress the internal gasket. This nut allows components such as pumps and filters to be removed without cutting pipe. The white finish matches standard pool plumbing aesthetics.

Why This Part Matters
Union nuts are essential for maintaining serviceable plumbing connections. A cracked or missing nut prevents proper sealing and limits equipment access. Using the correct union nut ensures consistent gasket compression and protects threads. OEM parts reduce the risk of leaks and misalignment.
