Legend Valve 105-453NL 1/2 in Press End Brass Check Valve

Product Description

The LEGEND VALVE 105-453NL is a forged brass in-line check valve designed to allow one-directional flow and prevent backflow in pressurized plumbing systems. Built with a brass body and a press end connection style, this valve is sized at 1/2 inch nominal and is suited for residential and light commercial water distribution lines. Licensed plumbers and pipefitters install this type of valve as part of potable water, hydronic heating, and general plumbing assemblies where backflow prevention is required at the line level.

This check valve is intended for in-line installation in 1/2 inch press-fit plumbing systems. The press end style eliminates the need for soldering or threading, making it compatible with modern press-fit tool systems commonly used in copper and compatible tubing installations. It is a practical choice for new construction and retrofit applications where a clean, no-flame connection is preferred or required by local code.
