Product Overview
The Waterway 415-4000 1.5" Union Nut is a serviceable plumbing component used in pool and spa circulation systems that incorporate 1.5-inch union fittings. Union assemblies are typically installed at equipment connection points to allow quick removal of pumps, filters, and heaters without cutting rigid PVC lines. The union nut threads onto the matching tailpiece and compresses the O-ring to create a pressure-tight, leak-resistant seal.
Manufactured from high-quality white PVC, this union nut is built to withstand continuous water flow, system vibration, and long-term exposure to sanitizers and balancing chemicals. Proper installation with compatible union components restores reliable sealing performance and maintains the integrity of the plumbing system without requiring full reconstruction.
