Description / Abstract: ISO 14540:2013 specifies dimensional and performance requirements for hydraulic screw-to-connect quick-action couplings designed to be used at pressure of 72 MPa (720 bar) 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. ISO 14540:2013 covers two types of such couplings: the "P" type, which has a poppet valve, and the "S" type, which has a spherical valve.
