A.y. Mcdonald 5426-031 Ball Valve 1/2 Inch Cts Push-on

Product Description

The A.Y. MCDONALD 5426-031 is a standard port ball valve designed for 1/2-inch CTS (copper tube size) connections using a push-on, removable fitting interface. Ball valves of this type provide a quarter-turn shutoff for water supply lines, making them a reliable isolation fitting in residential and light commercial plumbing systems. The push-on, removable connection style allows for tool-free installation and future serviceability without cutting the line. At 0.51 pounds, this is a compact, lightweight valve suited for tight spaces in typical supply line runs.

This valve is intended for use in potable water distribution systems where a CTS push-on connection is preferred. Common install scenarios include under-sink supply shutoffs, water heater isolation, and branch line control in residential construction and remodel work. The removable push-on design is especially useful in retrofit applications where soldering or compression fittings are not practical. Licensed plumbers and pipefitters are the primary installers in professional trade settings.
