When using cryogenic liquid gases with a low heat of vaporization such as helium, hydrogen or neon, it is necessary to have an efficient transfer hose/line. To meet these operating requirements, Cryofab transfer lines are carefully fabricated using all-welded stainless steel construction and super-insulated to provide the optimum in thermal performance. The inner configuration of all assemblies, whether it be rigid tube or flexible is stainless steel of minimum wall thickness to reduce cool-down losses and heat leak.

All hose assemblies are helium mass spectrometer leak tested and fully evacuated before shipping to ensure that the unit is ready for immediate use upon receipt.

All Cryofab transfer lines are custom built to meet the customer’s specific requirements for configuration, diameter, and length. Special features can be added to enhance the product.

Common applications include MRI and NMR refilling of superconducting magnets, gas distributor trans-fill stations, instrumentation and experimental transfers.

1. Globe valve can be tilted to reduce height.
In most cases terminal fittings or interface feed throughs will limit the working pressure of an assembly to 150PSI or less.

CFHT Series Bayonet Couplings

liquid helium transfer line bayonet connection
Bayonet Couplings are available as a set or individually as male and female. This option allows for easy disassembly of transfer equipment without the removal of a section from an experiment or storage dewar. Bayonets transform single construction transfer hoses into multiple parts for ease of use and flexibility in tight locations.
