Midland Industries Air Valves

Overview

The MIDLAND INDUSTRIES 943284 is a radiator air valve designed to bleed trapped air from steam and hot water radiator systems. Constructed with a brass body for corrosion resistance and durability, this valve connects via a 1/8-inch nominal male pipe thread (MPT) fitting. Removing trapped air from radiators improves heat distribution and system efficiency. It is a standard component installed by plumbers and HVAC technicians servicing residential and light commercial hydronic heating systems. This air valve is suited for use on cast iron and steel radiators found in residential and light commercial steam heating systems. It is installed at the air vent port on the radiator body, allowing air to escape while retaining steam and hot water. The 1/8-inch MPT connection is a widely used standard size for radiator air vent ports on single-pipe and two-pipe steam systems.
