Sandblast & Air Hose Couplings

Dultmeier Sales offers quality universal air couplings from Dixon and Kuriyama of America. Also known as "Chicago couplings", they provide a fast, secure, and versatile solution for connecting air lines in a wide range of pneumatic applications. These universal couplings are ideal for almost any type of pneumatic equipment. Commonly used with industrial air compressors, sandblasters, and air tools.

Universal Compatibility (1/2″ to 1″)

Each air fitting features a standardized universal head that allows direct connection between any two fittings—hose ends, male NPT, or female NPT—within the 1/2″ to 1″ size range. No matter the threaded or hose end style, you’ll get a secure and leak-resistant fit.

Fast, Tool-Free Connections

Universal air couplings are quick to install: simply push the heads together and turn a quarter turn clockwise. Once aligned, insert the included safety clip (or cotter pin) to prevent accidental disconnection under pressure.
