Nibco NN998H6W 0.5 Inch Cts Push Full Port Ball Valve

Product Description

The NIBCO NN998H6W is a lead-free brass full-port ball valve designed for 0.5-inch CTS (copper tube size) push-to-connect installations. It provides a full-bore flow path, minimizing pressure drop across the valve compared to standard-port designs. The push-fit end connection allows for tool-free joining to copper, CPVC, or PEX tubing in compatible sizes, making it well suited for potable water and hydronic plumbing systems. Licensed plumbers and pipefitters typically install this valve in residential and light commercial applications where shutoff service access and low-lead compliance are required.

This ball valve is intended for use in 0.5-inch CTS push-fit plumbing systems, including domestic hot and cold water supply lines, in-line shutoff points, and branch isolation. Its lead-free brass construction makes it appropriate for potable water service where lead content regulations apply, such as those enforced under the Reduction of Lead in Drinking Water Act. It is a practical choice for new construction plumbing, remodel work, and service replacements in residential and light commercial settings.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before installing or removing the valve.
