Description (English):

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.

Abstract

Overview - ISO 6150:2018 (Pneumatic fluid power quick-action coupling plugs)

ISO 6150:2018 specifies plug connecting dimensions, tolerances, specifications, application guidelines and testing for cylindrical quick-action couplings used in pneumatic fluid power systems. It ensures the interchangeability of cylindrical quick‑action coupling plugs for three maximum working pressure series: Series A (1 MPa / 10 bar), Series B (1.6 MPa / 16 bar), and Series C (2.5 MPa / 25 bar). The standard covers only the dimensional criteria of plugs (socket construction is left to the manufacturer) and provides the tests to be applied when plugs are used together with sockets.

Key topics and technical requirements

Dimensional standards and tolerances for plugs by series (A, B, C) - nominal diameters and geometric limits to ensure interchangeability.
Classification by maximum working pressure: 1 MPa, 1.6 MPa, 2.5 MPa (10 / 16 / 25 bar).
Material, hardness and surface finish: manufacturers choose materials but sealing surface roughness R_a ≤ 3.2 µm is specified.
Corrosion protection: plugs must meet corrosion test requirements (see test procedures).
Durability and life: couplings shall withstand 5 000 coupling/uncoupling cycles at maximum working pressure without failing manufacturer requirements.
Pressure and strength tests:
- Pressure test at 1.5 × maximum working pressure.
- Design strength to withstand 4 × maximum working pressure.
- Structural rigidity: specified radial and axial load resistance (document gives detailed values).
Operational testing: connect/disconnect forces, leakage measurement at maximum working pressure, extreme temperature tests, and functional tests for limited rotation/self-alignment.
Designation format: e.g., “Coupling ISO 6150-B-15” for a Series B, 15 mm nominal diameter plug.

Applications and who uses ISO 6150

Manufacturers and designers of pneumatic couplings, plugs and fittings who need to ensure mechanical interchangeability and conformity with international dimensions.
Product engineers and OEMs integrating quick-action couplings into pneumatic tools, lines, actuators and automated equipment.
Quality assurance, test labs and procurement teams for verifying compliance (dimensional checks, pressure and corrosion tests).
Maintenance, service and safety engineers selecting replacement plugs compatible with existing sockets.
Useful in industries using pneumatic fluid power: manufacturing, automation, tooling, robotics, and mobile equipment.

Normative references cited by ISO 6150: ISO 4414 (pneumatic system safety), ISO 5598 (fluid power vocabulary), ISO 9227 (salt spray corrosion tests).

Keywords: ISO 6150, pneumatic fluid power, cylindrical quick‑action couplings, plug dimensions, interchangeability, 10 bar, 16 bar, 25 bar, quick-action coupling testing, coupling plug standards.
