Legend Valve 313-280 1 in Cts X 3/4 in Fip Adapter

Product Description

The LEGEND VALVE 313-280 is a CTS (Copper Tube Size) to FIP (Female Iron Pipe) transition adapter designed for use in non-potable water piping systems. This fitting connects 1-inch CTS tubing to a 3/4-inch female iron pipe thread, making it a practical solution for irrigation, reclaimed water, and other non-drinking water applications. This part is not approved for potable water service after 2013 and must be used in compliance with applicable local plumbing codes. Licensed plumbers and irrigation contractors are the primary installers of this fitting.

This adapter is suited for residential and light commercial non-potable water systems, including irrigation supply lines, reclaimed water distribution, and similar piping configurations. The 1-inch CTS inlet accommodates standard plastic or copper tubing, while the 3/4-inch FIP outlet threads onto common pipe fittings and valves. Always verify local code requirements regarding material approval and application before installation.
