Nibco NL0Z00B Gate Valve 1-1/4 Inch Threaded Bronze

Product Description

The NIBCO NL0Z00B is a rising stem gate valve designed for full-flow isolation in plumbing and piping systems. Built with a bronze body and union bonnet construction, this valve handles 1-1/4 inch threaded pipe connections rated to 125 pressure class. The solid wedge disc provides positive shutoff with minimal turbulence when fully open. The rising stem design gives the installer a clear visual indicator of valve position — open or closed — without guesswork. Licensed plumbers and pipefitters install this type of valve in commercial and residential water distribution, heating systems, and light industrial piping where reliable manual isolation is required.

This gate valve fits 1-1/4 inch threaded pipe and suits a wide range of applications including domestic water supply, hydronic heating distribution lines, and general service piping. The union bonnet allows the internal components to be accessed for inspection or service without removing the valve body from the line, reducing downtime during maintenance. It is suitable for above-ground and accessible in-wall piping installations where a rising stem configuration is acceptable.

Designed as an OEM-style replacement or new-installation gate valve for 1-1/4 inch threaded pipe systems operating within 125 pressure class service conditions.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before installing or servicing this valve. Apply appropriate thread sealant or PTFE tape to the male threads before making up connections — do not overtighten. Confirm the valve is in the fully open position before returning the system to service to avoid flow restriction.
