Symmetrical quick release couplings VSU

These compact full flow couplings offer an optimum flow rate/pressure drop ratio. Since they consist of two perfectly symmetrical parts, there is no difference between the male/female hoses to be connected; thus they are fitted with identical mating halves. A well designed system of lugs and spherical valves ensures a totally safe exchange during connection and disconnection.
