The DURA PLASTIC 457-005 is a Schedule 40 PVC union fitting designed for 1/2 inch nominal pipe in pressure plumbing and fluid-handling systems. It uses a socket end style connection and seals with a Buna-N O-ring, providing a reliable, leak-resistant joint that can be disassembled without cutting pipe. This fitting is domestically manufactured to SCH 40/STD wall dimensions and is suited for potable water, irrigation, pool and spa, and general industrial piping applications. Licensed plumbers and pipe fitters install this type of union wherever periodic service access or equipment removal is required.
This union is appropriate for residential and light commercial systems where 1/2 inch PVC pipe is used. Common install scenarios include pump connections, filter assemblies, chemical dosing systems, and any branch or inline location that requires future disconnection. The socket end style accepts standard 1/2 inch Schedule 40 PVC pipe and is solvent-cemented during assembly. Pool and spa service technicians frequently use this fitting when installing or replacing circulation pumps and ancillary equipment.
Designed as an OEM-style replacement or new-install union fitting for 1/2 inch nominal Schedule 40 PVC piping systems in plumbing, irrigation, pool, spa, and light industrial applications.
Installation is performed by a licensed plumber or qualified pipe fitter following applicable IPC and local plumbing codes. Shut off system pressure and drain the line before disassembly or installation. When solvent-cementing the socket ends, use a PVC primer and cement rated for the pipe schedule and fluid service. Do not over-torque the union nut; hand-tight plus a quarter turn is the standard practice for threaded union rings on PVC fittings.
