Quick Release Couplings

The latest self-venting couplings - series 12S.C and BiTec

In June 2016 STEINCO launched the latest generation of its self-venting coupling series into the market.

Compressed air is a basic resource in industrial companies. Again and again many dangerous and partially serious accidents happen in conjunction with compressed air that not just result into high costs but also threaten human life. The dangerous whiplash effect is a well-known reason for such incidents. A further disadvantage of conventional couplings are extremely loud noises while decoupling.

The solution: the self-venting couplings series 12S.C and BiTec

These quick release couplings characterize that they are decoupled in two steps.

The plug is separated from the coupling pressureless. 

Both quick release couplings fulfill the high requirements of the DIN EN ISO 4414 (fluid technology- general rules and safety requirements to pneumatic systems and their components)


One feature of series 12S.C is its conspicuous green release sleeve along with its ergonomic design that allows a simple handling. A high safety standard is guaranteed.

The decoupling process is initiated by the two following steps:

  • By pushing the release sleeve back, the first part of the looking mechanism is released. The valve closes and the hose is vented.
  • By pulling the release sleeve forward the plug is released

The complete coupling is vented. By activating the release sleeve the plug can be released powerless and safe.


Bitec- the name of the coupling stands for two technologies that are connected with each other. Due to a patented combination from quick release coupling and sliding valve a pressureless coupling process is possible just with a little effort.

The BiTec is the only available quick release coupling, that hasnĀ“t to be coupled against working pressure. 

The BiTec is highly energy-saving, because a complete ventilation of the coupling can be done at the end of a working day. There is no unnecessary usage of energy (compressed air).

Applications are possible in many areas. The self-venting couplings will be applicable in many different fields as pneumatic, machinery and plant engineering, compressors, fluid engineering (hoses / rubber articles) general industry, vehicle technique, packaging industry, pneumatic nail gun

Meanwhile more and more industrial companies equipped their factories with the new STEINCO products and are convinced of their safety guarantee.
