Nibco NL1T00A Gate Valve 1 Inch Threaded Bronze

Product Description

The NIBCO NL1T00A is a non-rising stem gate valve designed for 1-inch threaded pipe connections in plumbing, heating, and mechanical systems. Constructed with a bronze body and a solid wedge disc, this valve provides reliable full-bore shutoff in applications where space above the valve is limited. The union bonnet design allows internal access for repacking without removing the valve from the line. Rated at 150 PSI, it suits a wide range of commercial and residential service conditions. Licensed plumbers and pipefitters are the primary installers of this valve type.

This valve is suited for hydronic heating systems, domestic water distribution, and general-purpose plumbing applications in both residential and light commercial settings. The threaded end connection accepts standard NPT pipe, making it a common choice for retrofit and new-construction installations where soldered or press fittings are not specified. The non-rising stem keeps the overall installed height compact, which is useful in tight mechanical rooms or below-slab installations.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off the water supply and depressurize the line before installation or servicing. Apply thread sealant or PTFE tape to male NPT threads before make-up, and do not over-tighten connections in bronze-body valves. Gate valves are intended for full-open or full-closed service and should not be used for throttling flow.
