If we consider the worldwide market, nowadays the use of "flat-face" quick-release couplings is well consolidated, especially for building & construction and industrial applications.
Consequently, a specific ISO standard (ISO 16028) has been developed, which specifies basic dimensions and performances (such as working pressure, flowrate, etc...) in order to grant a perfect interchangeability among the couplings manufactured by several companies in the world.
The main benefit of this coupling is the perfect flatness of the mating surfaces directly involved in the connection process both on the female part and on the male one.
This fact dramatically reduces the oil waste during disconnection process (so called "spillage") and makes it very easy to keep clean the mating faces in order to prevent dirt inclusions in the hydraulic system: for this reason it is a clean and ecological product as there is no oil waste in the environment.
The second feature or this coupling is the possibility to connect simply by pushing the male part into the female and the possibility to disconnect simply by pulling the male part in the opposite direction.
A further important feature of this product is the unblocking system for the external slider, very useful in case of dirty environment or wrong use of the coupling.
