Nibco NL1J00B Gate Valve 1-1/4 in Threaded Bronze

Product Description

The NIBCO NL1J00B is a non-rising stem gate valve designed for isolation service in commercial and residential plumbing, hydronic heating, and general-purpose piping systems. Built with a bronze body and solid wedge disc, it handles 1-1/4 inch threaded pipe connections and is rated to 150 pressure class. The screw-in bonnet provides a secure, field-serviceable seal. This valve is installed by licensed plumbers and pipefitters where a compact, full-bore shutoff is required and where vertical space above the valve is limited, making the non-rising stem design the preferred choice.

This gate valve is suited for 1-1/4 inch threaded piping runs in residential and light commercial applications. Typical installations include domestic water supply lines, hydronic heating distribution circuits, and industrial fluid handling systems where bronze construction is appropriate for the service fluid. The wheel handle allows for manual operation in accessible locations. It is specified in systems requiring Class 150 service ratings.

Key Features

• Non-rising stem design conserves vertical clearance above the valve during operation
• Bronze body construction offers corrosion resistance for water and compatible fluid service
• Solid wedge disc provides reliable full-bore shutoff with minimal flow restriction
• Screw-in bonnet allows field servicing and repacking without removing the valve from line
• Threaded end connections suit standard NPT pipe fittings in 1-1/4 inch size

Compatibility

Designed as an OEM-style replacement or new-installation gate valve for 1-1/4 inch NPT threaded piping systems requiring a Class 150 bronze non-rising stem gate valve.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code (IPC). Shut off system pressure and drain the line completely before removing or installing the valve. Apply thread sealant or PTFE tape to NPT threads per local code requirements. Do not overtighten threaded connections, as bronze fittings can be damaged by excessive torque.
