Self-Venting System
Nominal Diameter
10 = 80 mm²
RECTUS Series
27KE
Chart
Technical Description
With nominal diameter 10, one of the largest range in a new generation of couplings with ventilation technology. Two-stage uncoupling prevents occurence of the whiplash effect.

Advantages
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.

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.
