Midland Industries 28597B Aro 210 Hose Id Plug Brass

Product Description

The MIDLAND INDUSTRIES 28597B is a brass hose ID plug designed for ARO 210 interchange pneumatic systems. It features a male ARO 210 profile connection on one end and a 3/8-inch hose barb on the other, with a 1/4-inch body size. This plug is used to cap or terminate air lines in pneumatic tool and equipment setups, preventing air loss when a tool or fitting is disconnected. Rated for a maximum operating pressure of 250 psi, it is built from brass for durability and corrosion resistance in compressed air applications. Licensed HVAC and mechanical contractors, as well as pneumatic system technicians, typically install this type of fitting.

This plug is suited for use in pneumatic tool circuits, air supply lines, and workshop compressed air systems that use the ARO 210 interchange standard. The ARO 210 profile is a widely adopted interchange format, making this plug compatible with ARO 210-series quick-disconnect systems commonly found in industrial and commercial settings. It is appropriate for both new installations and service work where an open port needs to be safely plugged during maintenance or reconfiguration.
