The 37KE series is a single shut-off one-hand operating self-venting coupling. The large nominal diamter makes the 37KE especially suited to mains and supply pipes. Coupling is achieved in the same way as with all series couplings - simply by pushing the plug into the coupling. When uncoupling, the first lock is released by pulling the sleeve forward in the direction of the plug. This allows the compressed air to escape of the plug. The second locking system is released by pushing the sleeve back - it is only now, that the plug can be tanken out safely.

Connected in the same manner as all standard couplings – single hand operation. The venting takes place without any danger to the operators during the disconnecting process – no danger of being hit by a whipping hose that is still pressurized. The system fulfils the requirements stipulated in ISO 4414 for increased safety standards in the working place.

Not recommended for direct connection to compressed air tools. Reliable functioning can only be guaranteed in conjunction with original Rectus plugs
made of steel.
