This publication covers the performance standards required for crush-style and encircled elastomeric gaskets used in medical oxygen service up to 3000 psi at 70 °F (21.1 °C). Sealing gaskets designed to be used with a CGA connection no. 870 shall be qualified at the time of design by the manufacturer in accordance with this performance standard.

For additional information, see V-24, Guideline for Use of Gaskets in High Pressure Medical Oxygen Cylinder Service.

It is acknowledged that previous editions of this standard used a lower test pressure for qualification of gaskets as the CGA connection no. 870 is currently rated at 3000 psi at 70 °F (20 680 kPa at 21.1 °C) as per CGA V-1, Standard for Compressed Gas Cylinder Valve Outlet and Inlet Connections. The test pressures in this edition were increased to 3600 psi (24 800 kPa). Gaskets qualified at the lower test pressure as specified in previous editions of this publication (2400 psi) are acceptable for continued use in medical oxygen service up to 2216 psi.

The effective date of this standard is two years from the date of the publication of this edition, which was August 19, 2022. Gaskets manufactured on and after the effective date of this standard shall be in compliance with this standard.
