CGA V-7.1 – Standard Method for Determining Cylinder Valve Outlet Connections for Medical Gases, Second Edition

This standard applies to the selection of an appropriate cylinder valve outlet connection for medical gases for pressures up to 3000 psi (20 680 kPa) at 70 °F (21.1 °C). It does not apply to industrial gas mixtures, cylinders manifolded in transport and use, or to mixtures at higher pressures. Both threaded and pin-indexed connection assignments are included with reference to V-1.

This revision replaces the use of limited standards with alternate standards for the purpose of assuring only one connection assignment will be appropriate. This revision brings consistency with ISO 407:2004, to standardize pin-indexed yoke-type valve connections globally [4].
