scope:

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 cylindrical quick-action couplings for maximum working pressures of 10 bar¹⁾, 16 bar and 25 bar (1 MPa, I,6 MPa and 2,5 MPa) for use in pneumatic fluid power systems.

NOTE - Quick-action couplings with shut-off valves for equipment for welding, cutting and related processes are covered by IS0 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 International Standard. It does not apply to their functional characteristics.
