CGA V-17 (R2022)

In 1989, the Compressed Gas Association, Inc. (CGA), approved a new group of cylinder valve outlet connections assigned as the CGA 630/710 series. This series was conceived to provide higher purity and leak integrity than previous connections. Extensive design and testing was undertaken by CGA’s Cylinder Valve Committee, formerly known as the Connections Standards Committee, to fulfill these requirements. Refer to drawings 630 and 710 in CGA V-1, Standard for Compressed Gas Cylinder Valve Outlet and Inlet Connections for complete design information.

This publication provides guidelines for the assembly of CGA 630/710 series ultra high integrity service connections.
