The Compressed Gas Association (CGA) has long recognized the need to promote safety in the use of gases and equipment for welding, cutting, and allied processes. Hose line quick-connect couplings are commonly used in these processes as an alternative to the traditional threaded hose line connections.
This publication applies to quick-connect couplings with integral CGA E-1 or ISO/TR 28821, connections used between regulators, torches and/or other gas welding equipment, sometimes referred to as hose-type quick-connects, for pressures up to 200 psi (1380 kPa). This publication covers requirements and considerations for design and maintenance of indexed pin-type noninterchangeable welding quick-action couplings. It is the intention of this publication to provide some guidance because of the various designs that exist.
This publication does not replace or overrule the connection requirements of CGA E-1 or ISO/TR 28821
