Magic Plastics 1.5" Split Nut, Small Flange, Pump Union w/Screws MAG0121109015

The Magic Plastics 1.5" Split Nut, Small Flange Pump Union w/Screws (MAG0121109015 / 0121109015) is a repair-style union nut designed to replace cracked or broken pump union nuts without cutting out existing plumbing. The split design opens around the existing tailpiece and threads, then bolts back together to restore a secure, leak-resistant connection.

Key Features & Benefits

1.5" FBT (Female Buttress Thread) sizing fits most standard 1.5" pump union tailpieces on pools and spas, making it a versatile replacement option.
Small flange profile matches original pump union small-flange designs, helping ensure proper sealing against the pump or filter face.
Split nut construction allows installation over existing plumbing without cutting or re-gluing pipes—ideal for quick repairs when only the nut has failed.
Includes screws to clamp the two nut halves together securely, restoring full clamping force on the union O-ring for a watertight seal.
Durable molded plastic body resists corrosion and typical pool and spa chemicals for long service life in pump room or equipment pad environments.
