The MIDLAND INDUSTRIES 28580 is a steel automotive interchange male plug designed for pneumatic quick-connect systems. It features a 1/2-inch body size with a male automotive interchange profile on one end and a 3/4-inch male NPT thread on the other. Built from steel for durability in demanding shop and service environments, the 28580 is rated to a maximum operating pressure of 300 psi. This fitting is installed by HVAC technicians, mechanics, and pneumatic system technicians who need a reliable plug to connect air tools or pneumatic lines to standard interchange-style couplers.
The 28580 is suited for use in pneumatic air supply systems, automotive service bays, and industrial shop environments where Parker or automotive interchange style quick-connect fittings are standard. The 3/4-inch male NPT thread connects to standard pipe or manifold ports, while the 1/2-inch body mates with automotive interchange couplers commonly found in production and service settings.
Compatible with Tru-Flate connectors and designed for use in Parker and automotive interchange style pneumatic quick-connect systems.
Installation is performed by qualified pneumatic system technicians or mechanics. Depressurize and isolate the air supply line completely before connecting or disconnecting any pneumatic fitting. Apply appropriate thread sealant to the NPT threads per the fitting manufacturer's guidance and applicable codes. Do not exceed the rated 300 psi maximum operating pressure.
