Midland Industries 28585 Aro 210 Female Coupler Brass

Product Description

The MIDLAND INDUSTRIES 28585 is a brass female coupler built to the ARO 210 interchange profile, designed for use in compressed air and pneumatic tool systems. The coupler features a 1/4-inch body with a 3/8-inch female NPT inlet, allowing connection to a wide range of pneumatic hoses and fittings that meet the ARO 210 standard. Rated to 250 psi maximum operating pressure, this coupler is suited for shop air systems, production lines, and mobile service applications where reliable, quick-connect performance is required. Installation is typically handled by HVAC technicians, industrial mechanics, or plumbers working with compressed air systems.

This coupler is intended for pneumatic applications requiring ARO 210 interchange compatibility. The 3/8-inch female NPT port threads directly onto standard hose ends, manifolds, or compressed air supply lines. The brass construction provides corrosion resistance in environments with moisture or mild chemicals. It is commonly used in shop air distribution setups, pneumatic tool connections, and light industrial compressed air systems where ARO 210 profile quick-connect couplers are specified.

Compatibility

Designed as an OEM-style replacement or direct-fit coupler for pneumatic systems using the ARO 210 interchange standard, accepting 3/8-inch female NPT connections.

Installation Notes

Depressurize and disconnect the air supply completely before servicing or replacing any pneumatic quick-connect coupler. Use appropriate thread sealant on NPT connections and verify that thread pitch and size match before assembly. Overtightening brass fittings can cause cracking, so tighten to hand-snug plus a conservative wrench turn. Verify system pressure does not exceed the 250 psi rating of this coupler after reinstating the air supply.
