Midland Industries 28526S Female Coupler 3/8 in Npt Steel

Product Description

The MIDLAND INDUSTRIES 28526S is a steel automotive interchange female coupler designed for compressed air and pneumatic tool applications. It features a 3/8-inch body with a female automotive interchange profile on one end and a 3/8-inch female NPT connection on the other, making it a direct-connect fitting for air lines and pneumatic equipment. Rated to 300 psi maximum operating pressure, this coupler is built for reliable daily use in shop and field environments. It is installed by HVAC technicians, plumbers, and general contractors running pneumatic tools from portable or stationary compressors.

The 28526S is suited for residential and light commercial pneumatic systems where the automotive interchange profile is the standard connection type. It is compatible with Tru-Flate connectors, making it interchangeable within that widely used ecosystem. Typical installation involves connecting an air hose or tool fitting directly to a compressed air supply line. The female NPT thread allows direct installation into standard pipe fittings, manifolds, or air line drops.
