Midland Industries 40061-08 Boiler Drain Valve 1/2 in Mpt

Product Description

The MIDLAND INDUSTRIES 40061-08 is a boiler drain valve designed for 1/2-inch nominal pipe with a male pipe thread (MPT) connection. This valve provides a controlled drain point on boilers, water heaters, and hydronic piping systems, allowing technicians to flush sediment, relieve pressure, or isolate and drain a system section during service. At 0.385 pounds and measuring 4 inches in length, 2.9 inches in width, and 1.95 inches in height, it is a compact, practical fitting suited for tight mechanical room installations. Installation is performed by licensed plumbers and HVAC technicians.

This boiler drain valve is used in residential and light commercial hydronic heating systems, water heater drain applications, and general plumbing service points where a reliable threaded drain valve is required. The 1/2-inch MPT connection makes it compatible with standard threaded pipe assemblies commonly found in boiler supply and return lines as well as storage water heater drain ports.
