The CB700 Series Cryogenic Bayonet design is a tube-sized high-efficiency connection for vacuum-insulated piping and transfer line applications. This series utilizes a threaded connection nut to facilitate easy connection and separation functions. A close tolerance seal design maximizes the efficiency and a silicone O-ring assures tight sealing at cryogenic temperatures. The bayonet is available in four lengths, 3″, 6″, 9″ & 15″ to interchange with new or existing installations. The CB700 will operate efficiently in the vertical or horizontal positions and is recommended for use with most cryogenic fluids including nitrogen, oxygen (with proper cleaning) argon and helium.
