Hansen 2RL Series

Danfoss Hansen 2RL ring-lock pneumatic quick disconnect couplings combine high flow capacity with push-to-connect operation and a rotating safety sleeve for compressed-air systems.

Series Overview

Compact 1/4-inch ring-lock coupling

The Hansen 2RL Series uses a proprietary Danfoss interchange for compressed air. Its ring-lock sleeve helps prevent accidental disconnection while retaining simple push-to-connect operation.

To disconnect, rotate the sleeve approximately 20 degrees before retracting it. The 2RL is suited to shipyards, general pneumatics, mining and marine applications.
