Legend Valve 313-180NL Brass Coupling 1x0.75 in 100 Psi

Product Description

The LEGEND VALVE 313-180NL is a brass compression-by-female-iron-pipe (FIP) coupling designed to join a 1-inch compression connection to a 3/4-inch FIP threaded connection in potable water and general plumbing systems. Machined from solid brass, the fitting delivers reliable sealing at operating pressures up to 100 psi. The compression end creates a leak-resistant joint without soldering, while the FIP end threads onto standard female pipe threads. Plumbers and pipefitters install this coupling in residential and light commercial supply lines where a transition between connection types is required.

This coupling is suited for residential water supply systems, light commercial plumbing, and retrofit applications where a compression fitting must tie into an existing female-threaded port. The 1-inch compression inlet accommodates standard copper or compatible tubing, and the 3/4-inch FIP outlet connects to threaded valves, supply stubs, or manifolds. It is commonly used in under-sink supply lines, water meter connections, and service entry transitions.

Key Features

• Compression-to-FIP configuration allows solder-free connection to female-threaded fittings
• Brass construction resists corrosion in potable water service
• Rated to 100 psi operating pressure for residential and light commercial use
• Compact profile at 3.41 inches length for use in tight spaces
• Single-piece solid brass body for long service life

Compatibility

Designed as an OEM-style plumbing replacement and new-installation fitting suitable for 1-inch compression tubing connections to 3/4-inch female iron pipe threaded ports in standard residential and light commercial water supply applications.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter in accordance with the International Plumbing Code (IPC) and local authority requirements. Shut off and depressurize the water supply line before beginning work. The compression end requires a properly cut, deburred tube end and a correctly seated ferrule for a leak-free joint. Do not overtighten the compression nut; follow standard hand-tight-plus-turns practice appropriate for brass compression fittings.
