This document specifies the dimensions and tolerances so as to ensure the interchangeability of pneumatic quick-action coupling plugs. It also provides specifications and application guidelines, and specifies the tests to be applied to the plugs together with sockets. NOTE 1 The construction and dimensions of sockets are left to the manufacturer's option. This document applies to cylindrical quick-action couplings for maximum working pressures of 1 MPa, 1,6 MPa and 2,5 MPa (10 bar, 16 bar and 25 bar) for use in pneumatic fluid power systems. NOTE 2 Quick-action couplings with shut-off valves for equipment for welding, cutting and related processes are covered by ISO 7289. This document applies only to the dimensional criteria of products manufactured in accordance with this document. It does not apply to their functional characteristics.
