Waterway Plastics 400-4060 Pump Union Nut - 1.5in x 1.5in Socket

What This Part Is Used For
The Waterway Plastics 400-4230 pump union nut is used to secure 1.5 inch union connections on pool and spa pumps. It threads onto the union tailpiece to compress the internal gasket and seal the connection. This nut allows pumps to be removed for service without cutting plumbing. It is a standard component in serviceable pump installations.

Why This Part Matters
A cracked or stripped union nut prevents proper gasket compression and leads to leaks at the pump connection. Improvised repairs often result in uneven pressure or damaged threads. Using the correct OEM union nut restores proper sealing and serviceability. Maintaining intact unions protects both plumbing and pump housings.
