Nibco NL94GFB Ball Valve 1-1/4 Inch Fnpt Carbon Steel 1500 Psi

Product Description

The NIBCO NL94GFB is a 1-piece standard manual ball valve designed for inline shut-off and flow control in pressurized piping systems. It features a 1-1/4 inch female NPT (FNPT) connection on both ends and accepts a lever handle for quick quarter-turn operation. The body and trim are carbon steel, rated for a maximum working pressure of 1500 psi and a maximum working temperature of 400 degrees F. Seats and seals are reinforced PTFE (polytetrafluoroethylene), providing chemical resistance and a reliable bubble-tight shutoff. This valve is suited for licensed plumbers, pipefitters, and mechanical contractors working on industrial, commercial, or heavy-duty residential piping.

The NL94GFB is well suited for hydronic heating systems, compressed air lines, water service, and general-purpose fluid handling applications where high-pressure ratings are required. The FNPT x FNPT end connections allow straightforward threaded installation into standard NPT piping. The lever handle enables fast visual confirmation of open or closed position, making it practical in mechanical rooms, utility spaces, and process piping installations.

Compatibility

Designed as an OEM-style replacement or direct-fit valve for 1-1/4 inch NPT threaded piping systems in commercial and industrial mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME B31 piping standards. Depressurize and drain the system fully before removing or installing any valve. Apply thread sealant or PTFE tape to NPT threads per standard practice, and avoid over-torquing threaded connections into the valve body ports. Verify that system pressure and temperature do not exceed the rated limits before returning the line to service.
