Pneumatic fluid power. Cylindrical quick-action couplings for maximum working pressures of 10 bar, 16 bar and 25 bar (1 MPa, 1,6 MPa and 2,5 MPa). Plug connecting dimensions, specifications, application guidelines and testing
This International Standard lays down the dimensions and tolerances so as to ensure the interchangeability of pneumatic quick-action coupling plugs. It also lays down specifications and application guidelines, and specifies the tests to be applied to the plugs together with sockets.
NOTE — The construction and dimensions of sockets are left to the manufacturer's option.
This International Standard applies to cylindrtcal quick-action couplings for maximum working pressures of 10 bar1), 16 bar and 25 bar (1 MPa, 1,6 MPa and2,5 MPa) for use in pneumatic fluid power systems.
NOTE — Quick-action couplings with snut -off valves for equipment for welding, cutting and related processes are covered by ISO 7289, Quick-action couplings with shut-off valve for welding, cutting and allied processes.2)
This International Standard applies only to the dimensional criteria of products manufactured in accordance with this Inter-national Standard. It does not apply to their functional characteristics.
