Pollution free, non-spill, flat faces mean that there is no introduction of air into the circuits on connection, and no lost of liquid on disconnection making complete circuit bleeding unnecessary. Light and compact couplings made from high performance treated aluminium alloy for light weight. Optimum flow with internal design ensures a low pressure drop for an optimum flow in compact overall dimensions.

It is also safe and robust-locking, with a large number of locking balls. The optional relief valve on the socket or plug side enables the release of pressure of the circuit caused, for example, by a rise in temperature in case of prolonged storage in the sun. SPT 10 and SPT 12 are available in multi-coupling versions for the simultaneous connection of several circuits.
