Legend Valve 457-020 Pvc Sch 40 Socket Union 2 Inches

Product Description

The LEGEND VALVE 457-020 is a 2-inch PVC Schedule 40 socket union fitted with a Buna-N O-ring seal. It is designed to create a removable, leak-resistant joint in gravity-fed and low-pressure piping systems. Plumbers and pipefitters install this union wherever a section of pipe must be disconnected for service, replacement, or inspection without cutting the line. The Schedule 40 wall thickness delivers reliable pressure-rated performance in standard residential and light commercial applications. The Buna-N O-ring provides a positive seal against water and many common chemicals encountered in plumbing service.

This socket union is suited for use in residential and light commercial cold and hot water supply lines, drain and recirculation systems, irrigation manifolds, and pool or spa plumbing where PVC is the specified pipe material. The 2-inch socket end configuration accepts standard Schedule 40 PVC pipe cemented in place on both sides, allowing the union nut to be threaded apart for future access. It is a common component in pump installations, filter housings, and chemical feed systems that require periodic maintenance access.

Compatibility

Installation Notes

A licensed plumber or qualified pipefitter should install this union in accordance with local plumbing codes and IPC guidelines. Shut off water supply and depressurize the line fully before cutting into an existing system. Use approved PVC solvent cement on the socket ends and allow full cure time before pressurizing. Hand-tighten the union nut until the O-ring seats, then snug as needed — do not over-torque the plastic nut.
