Legend Valve 313-105 Water Service Flare Union 1 in

Product Description

The LEGEND VALVE 313-105 is a 1-inch water service flare union designed for connecting and disconnecting water service lines without cutting pipe. This fitting uses a 1-inch flare x 1-inch flare end connection, making it well-suited for applications where a removable, pressure-tight joint is required. The T-4200 series union is built for water service applications and is typically installed by licensed plumbers on residential and light commercial water lines. Its symmetrical flare-to-flare configuration simplifies in-line installation and future serviceability.

This flare union is intended for water service piping applications. It connects two 1-inch flared tube ends, providing a leak-resistant mechanical joint without soldering or threading. Common installation scenarios include water supply lines, service entry connections, and locations where periodic disconnection of the line may be required. The fitting is packaged 36 pieces per case, making it practical for contractors stocking service vans or supply rooms.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements.

Ensure flare seats on both tube ends are clean, undamaged, and properly formed before tightening the union nut. Do not overtighten flare nuts, as this can deform the flare seat and cause leaks.
