Nibco NF998X8 3/4 Inch Female Press Ball Valve Brass

Product Description

The NIBCO NF998X8 is a 3/4 inch nominal full port ball valve designed for press-fit installation in plumbing and hydronic systems. The brass body provides corrosion resistance in potable water and heating applications. EPDM/PTFE softgoods deliver reliable sealing performance across a range of operating temperatures. The female press end style allows tool-based installation without open flame, making it well suited for residential and light commercial work where soldering is restricted or impractical. Licensed plumbers and hydronic technicians are the primary installers of this valve type.

This valve is configured for female press connections on both ends, compatible with standard press-fit copper tubing systems. The full port design minimizes flow restriction, which is important in hydronic loops, domestic water distribution, and other applications where pressure drop must be kept low. The low-lead brass construction aligns with lead-free requirements for potable water service. It is appropriate for use in residential and commercial plumbing systems where a shutoff or isolation point is needed.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines.
