Legend Valve 310-141NL Brass Pipe Union 1/4 in Mnpt Fnpt 125psi

Product Description

The LEGEND VALVE 310-141NL is a 1/4 inch brass pipe union designed for threaded pipe assemblies in potable water systems. It connects male NPT to female NPT ends, allowing sections of pipe to be joined and later disconnected without cutting. The union is rated at 125 psi at Class 125, making it suitable for low-pressure domestic water lines. Licensed plumbers and qualified pipefitters install this fitting during new construction or when servicing existing supply lines where future disassembly is anticipated. The uncoated brass construction provides corrosion resistance appropriate for clean water service.

This union is intended for potable water applications in residential and light commercial plumbing systems. Its compact 1/4 inch size suits branch lines, fixture supply connections, and instrument isolation points where a union fitting is required to facilitate service access. The MNPT x FNPT end configuration threads directly onto standard NPT pipe or fittings without adapters.
