Mueller Industries 19070 Bronze Gate Valve 1-1/4 Inch Fnpt

Product Description

The MUELLER INDUSTRIES 19070 is a bronze gate valve with 1-1/4 inch female NPT (FNPT) connections on both ends. It is rated at 200 WOG (Water, Oil, Gas) and 125 WSP (Working Steam Pressure), making it suitable for a broad range of plumbing system shutoff and isolation applications. The valve body is constructed from bronze for corrosion resistance and long service life in wet environments. A solid wedge disc provides positive shutoff when fully closed. Licensed plumbers and pipefitters are the primary installers of this type of valve in residential and commercial systems.

This gate valve is intended for plumbing applications where full-bore, low-restriction flow control is required. Gate valves are typically installed as isolation or shutoff valves rather than throttling devices. The FNPT x FNPT end connections make this valve compatible with standard threaded pipe systems. It is well suited for water supply lines, general plumbing distribution, and similar service where the 200 WOG and 125 WSP pressure ratings meet system requirements.

Installation Notes

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