Hansen Auto-Flo 23 & 24 Series

High-flow, automatic quick-connect one-way couplings for compressed air service, with Auto-Flo 23 covering Industrial, ARO 210, and Tru-Flate interchange plugs and Auto-Flo 24 operating with CEJN 320 and Rectus 25 interchange plugs.

Series Overview

Automatic one-way couplings for high-flow compressed air service

The Auto-Flo 23 and 24 Series are 1/4 inch nominal one-way shut-off couplings designed for compressed air applications where fast connection, quick disconnection, and automatic socket shut-off are important. Both series are built around an automatic push-to-connect design with a sleeve guard to help protect against accidental disconnection.

Auto-Flo 23 is a universal socket platform that works with Industrial Interchange, ARO 210, and Tru-Flate plugs. Auto-Flo 24 is designed for CEJN 320 and Rectus 25 interchange plugs, giving it its own dedicated plug profile and flow capability.
