The Waterway 400-5090 Union Assembly is a factory-original 2-inch slip PVC union connector built for dependable plumbing joints in pool and spa circulation networks. Its self-aligning construction compensates for slight pipe offset during hookup, delivering a snug, leak-resistant connection every time.

Made from impact-resistant, pool-grade PVC, this union handles the continuous pressure, moisture, and chemical exposure that pool equipment plumbing demands. A precision-machined O-ring seal is included to form a watertight bond, preserving efficient water movement through pumps, filters, heaters, and other connected equipment.

The complete Waterway 400-5090 2-inch union assembly ships with the union body, threaded nut, and sealing O-ring, giving you every component necessary to establish or restore a solid plumbing connection in your pool or spa system.
