Midland Industries 28507S Female Coupler 1/4in Npt Steel

Product Description

The MIDLAND INDUSTRIES 28507S is a steel automotive interchange female coupler designed for pneumatic quick-connect applications. It features a 1/4-inch body with a 1/4-inch female NPT inlet and an automotive interchange profile on the connection end. Rated for a maximum operating pressure of 300 psi, this coupler is built for reliable, repeated connect-disconnect cycles in compressed air service. The all-steel construction provides durability in shop and industrial environments where resistance to wear and mechanical stress is required. HVAC technicians, plumbers, and general contractors working with air-powered tools and equipment will find this a straightforward drop-in component.

This coupler is suited for compressed air tool lines in residential and commercial service environments. It connects standard air hoses and pneumatic tools using the widely adopted automotive interchange profile. Typical install scenarios include service bays, mechanical rooms, and job-site compressor setups where quick tool changes are routine. The 1/4-inch female NPT thread allows direct attachment to standard threaded air line fittings and manifolds.
