Coilhose Pneumatics 165 Pneumatic Coupler 1/4 in Brass

Product Description

The COILHOSE PNEUMATICS 165 is a brass pneumatic hose coupler designed for use in compressed air systems requiring a Tru-Flate automotive interchange connection. It features a 3/8-inch MNPT threaded inlet and a 1/4-inch body diameter, making it a standard-size fitting for shop air lines and portable pneumatic tool setups. Rated to 300 psi maximum working pressure and rated for temperatures from -40 degrees F to 250 degrees F, this coupler handles the demands of daily shop and field use. It is installed by maintenance techs, industrial mechanics, and service professionals who need a reliable, interchangeable quick-connect fitting in brass construction.

This coupler is suited for residential and commercial shop environments where Tru-Flate automotive-style quick-connect fittings are the standard. Typical applications include connecting air hoses to compressors, inline regulators, and pneumatic hand tools. The 3/8-inch NPT male thread fits standard air line ports and manifolds commonly found in automotive service bays, fabrication shops, and general-purpose compressed air systems.
