Danfoss Hansen PneumaticQuick Disconnect Couplings

Pneumatic Coupling Solutions

Hansen pneumatic couplings cover miniature ball lock designs for compressed air, gases, and liquids, along with one-way shut-off safety couplings for gas fired equipment and fuel gas systems. This section can keep expanding as more Hansen pneumatic series are added.

Hansen Gas-Mate Series

One-way shut-off safety couplings designed for gas fired devices and related applications, with automatic shutoff when the plug is removed and a heat-sensitive plug that allows the socket valve to close in fire conditions.

Hansen 180/280 Series

Miniature ball lock quick disconnect couplings designed for use with compressed air, gases, and liquids. Series 180 uses a tire valve while Series 280 uses a 1HK valve for higher flow capacity.

Hansen 3000 Series

Industrial interchange pin lock pneumatic couplings for compressed air, gases, and liquids. The 3000 Series is the 1/4 body size platform in this family and sets the standard for pin lock style pneumatic couplings.

Hansen Auto-Flo 23/24 Series

High flow automatic pneumatic couplings designed for compressed air. Auto-Flo 23 accepts Industrial, ARO 210, and Tru-Flate interchange plugs, while Auto-Flo 24 works with CEJN 320 and Rectus 25 interchange plugs.

Hansen 210 Series

Pin-type one-way shut-off pneumatic couplings with automatic push-to-connect operation. The 210 Series uses a 1/4 body size for construction, maintenance, repair, in-plant industrial, and pneumatic tool service.

Hansen 310 Series

The 310 Series uses the same pin-type one-way shut-off design as the 210, but in a 3/8 body size for higher airflow in industrial pneumatic systems and tool applications.

Series In Development

Hansen 100 Series

Quick disconnect couplings designed to prevent the crossing of lines. The non-interchangeable design is used for compressed air and gases where line identification and separation are important.

Series In Development

Hansen Full-Bore Series

A premium automatic one-way shut-off coupling with a pressure-relieving feature and straight-through design for unimpeded airflow. Its two-sleeve release sequence helps prevent accidental uncoupling and hose whip.

Series In Development

Hansen 2RL Series

Ring lock quick disconnect pneumatic couplings with a proprietary Danfoss interchange for compressed air. The 2RL Series uses a 1/4 coupling size and a rotating sleeve design that helps prevent accidental disconnection.

Series In Development

Hansen 3RL Series

The 3RL Series brings the same ring lock concept to a 3/8 coupling size, combining high flow capacity with a sleeve that rotates about 20 degrees to disconnect and reduce accidental release.
