Nibco NF998X6 Ball Valve 1/2 in Female Press Full Port Brass

Product Description

The NIBCO NF998X6 is a full-port ball valve designed for use in pressurized plumbing and hydronic systems. It features a brass body with a female press end style connection, making it compatible with press-fit copper tubing systems used widely in commercial and residential water distribution. The valve carries EPDM and PTFE softgoods, which provide reliable sealing performance across a range of service temperatures. Full-port construction minimizes flow restriction, maintaining line velocity through the valve body. This valve is installed by licensed plumbers and pipefitters working on potable water, heating, and cooling distribution systems.

The NF998X6 is suited for residential and light commercial plumbing installations where a 1/2 inch nominal press-connection shutoff is required. Its press end style eliminates the need for soldering or threading, reducing installation time and open-flame risk in retrofit or new construction environments. The full-port design makes it appropriate for applications where minimal pressure drop across the valve is a system requirement.

Key Features

• Full-port ball valve for unrestricted flow through the valve body
• Female press end style connection — no soldering or threading required
• Brass body construction for durability in water service applications
• EPDM and PTFE softgoods for dependable seat and seal performance
• 1/2 inch nominal size suits standard residential and light commercial piping

Compatibility

Designed as an OEM-style press-fit ball valve replacement or new installation fitting for 1/2 inch nominal copper press systems in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable local plumbing code and IPC guidelines. Shut off and depressurize the water supply completely before installing or servicing this valve. Press-fit connections require the appropriate press tool and jaw set rated for the fitting size and material. Verify the pipe end is clean, free of burrs, and fully inserted to the stop before pressing.
