Technical Description
The connection is made the same way as with all other quick connect coupling series, by simply pushing the plug in the coupling. The audible latching when the plug is securely in place signifies that the coupling is locked. The sleeve must be pulled back to release the first locking system before it can be disconnected. This closes the coupling valve. The compressed downstream air can now escape from the plug (hose). Pulling the sleeve back a second time releases the second locking system. The connection can now be safely undone. This self-venting coupling, designed for bleeding off trapped air, is not suitable for direct connection to compressed air tools.

Advantages
The system fulfils the requirements of ISO 4414.
- increased safety standards in the work place
- the plastic sleeve does not scratch working surfaces

Caution
Not recommended for direct connection to compressed air tools. Reliable functioning can only be guaranteed in conjunction with original Rectus plugs
made of steel.
Working Pressure
PB = 12 bar,
maximum static working pressure with safety factor of 4 to 1.

Working Temperature*
-20°C up to +60°C (NBR)
depending on the medium.
