Insulon Vacuum Jacketed Hose for Liquid Hydrogen

All cryogenic fluids are not the same, and hydrogen presents specific challenges. Achieve maximum thermal performance for LH2 lines with Insulon vacuum jacketed hose. Improve energy efficiency for applications including H2 fuel cell electric vehicles, trucks, aircraft, and test laboratories.

Insulon hoses are uniquely engineered to deliver ultra-high performance in cryogenic hydrogen applications. Features include fully annealed materials to combat effects of hydrogen embrittlement, low non-volatile residue (NRV) on surfaces, and proprietary high-density multi-layer insulation (MLI). Additional benefits include typically smaller diameters than other vacuum jacketed hoses, and a hyper-deep vacuum space with no pump-down maintenance required.


  • Typically more compact design, smaller outer diameter when compared to other vacuum jacketed hoses
  • Fully annealed materials to combat effects of hydrogen embrittlement
  • Low non-volatile residue (NVR) on surfaces
  • ASTM G93 cleanliness up to Level A upon request
  • Low pressure and high pressure models available. (For ultra-high pressure vacuum jacketed hoses for cryo-compressed hydrogen transfer, please contact us)
  • 316L stainless steel inner and outer surfaces
  • Option to include high-density multi-layer insulation (MLI)
  • Lengths from 2 to 66 feet (0.6 to 20 meters)
