Midland Industries 28583 Aro 210 Female Coupler Brass

Product Description

The MIDLAND INDUSTRIES 28583 is a brass ARO 210 interchange female coupler designed for pneumatic tool and equipment connections. It features a 1/4-inch body with a 1/8-inch female NPT inlet and an ARO 210 profile female coupler end. Rated to a maximum operating pressure of 250 psi, this coupler is built for reliable service in compressed air systems. The all-brass construction resists corrosion and handles the mechanical demands of frequent connect-and-disconnect cycles in shop and field environments. HVAC technicians, plumbers, and general trade professionals use couplers like this on air hoses, pneumatic tools, and pressurized service equipment.

This coupler is suited for light-to-medium-duty pneumatic applications in residential and commercial settings. The ARO 210 interchange profile is a widely used quick-connect standard, making this fitting compatible with ARO 210-series plugs found on many pneumatic tools and air hoses. The 1/8-inch female NPT port threads directly onto standard NPT-threaded air line fittings, manifolds, or tool inlets. It is well-suited for workshop compressor setups, service van air systems, and any application requiring a dependable brass coupler at moderate pressure ratings.

Installation Notes

Depressurize and de-energize the air system completely before installing or removing any pneumatic fitting. Apply thread sealant tape to the NPT threads per standard practice before threading the coupler onto the port. Hand-tighten first, then snug with a wrench - avoid overtightening brass fittings to prevent thread damage. Verify the connection is leak-free before returning the system to service.
