Midland Industries 40072-08 Stop Valve 1/2 in Sweat

Product Description

The MIDLAND INDUSTRIES 40072-08 is a 1/2-inch nominal stop valve with a sweat connection designed for shutoff service in plumbing and mechanical systems. Stop valves provide a reliable means of isolating flow at a fixture, appliance, or branch line, allowing service or replacement without shutting down an entire system. This valve is sized at 1/2-inch nominal and connects via sweat, meaning it is soldered directly to copper tubing using standard torch and solder technique. Licensed plumbers and pipefitters are the primary installers of this type of valve in both new construction and retrofit applications.

This stop valve is suited for residential and light commercial plumbing applications where a compact, inline shutoff is required. Common install scenarios include fixture supply lines, appliance connections, and branch isolation points in copper piping systems. The sweat-end configuration makes it a direct fit into copper tube runs where threaded or push-fit fittings are not specified. It is appropriate for potable water supply and general plumbing service where a globe-style or straight stop valve is called for by the design or code requirement.

Key Features

• 1/2-inch nominal sizing fits standard half-inch copper tubing supply lines
• Sweat connection type allows direct solder installation into copper piping
• Designed for shutoff and isolation service at fixtures or appliances

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and fully drain the line before cutting into the pipe or removing an existing valve. Surfaces must be clean, deburred, and fluxed before soldering to ensure a leak-free joint. Allow the joint to cool completely before restoring water pressure and checking for leaks.
