Liquid Helium Transfer Hose/Line

CFHT Series

Liquid helium transfer hose connecting two dewars
custom liquid helium lines
truck mounted liquid helium transfer hose

Suitable for Cryogenic Helium, Hydrogen, or Neon

An efficient liquid transfer line is essential when using super-cooled gases that evaporate at a low temperature. To meet these operating requirements, Cryofab helium transfer hose 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 helium hose assemblies are mass spectrometer leak tested and fully evacuated before shipping to ensure that the unit is ready for immediate use upon receipt.

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.
