This International Standard specifies dimensional and performance requirements for hydraulic screw-to-connect quick-action couplings designed to be used at pressure of 72MPa (720bar1)in static conditions as an interface between a hydraulic power unit and a tool. Typical applications for these couplings are related to hydraulic jacks, rams, clamping devices, hand tools, and cylinders.
This International Standard covers two types of such couplings: the “P?? type, which has a poppet valve, and the “S?? type, which has a spherical valve.
1 1 bar = 100 kPa = 105 Pa = 0,1MPa; 1 Pa = 1 N/m2
