Vacuum insulated hose

Build your Insulon vacuum jacketed hose assembly

Insulon vacuum jacketed hoses are available in a variety of formats to offer you maximum versatility and control when purchasing vacuum jacketed hoses. Whether you need to safely transfer liquid nitrogen, chiller fluids, steam, or high temperature gases, the Insulon Hose product line can be adjusted to suit your specifications without overengineering. Select performance level, pressure rating, and optional end fittings to suit your specific application.


Cryogenic fluids

Reduce operating costs with low-maintenance, pump-down-free vacuum jacketed hoses for industrial gas supply, cryo-freezers, and cryogenic hydrogen applications.

Low-temperature chillers

Maximize energy efficiency and minimize condensation with easy-to-install Insulon Hoses for chiller supply and return lines. Available in lengths up to 20 meters (66 feet).

Process heating and cooling

Maximize performance for temperature control units (TCUs) used for process heating and cooling in semiconductor, chemistry, research, and laboratory applications.

Exhaust lines

Insulate high temperature exhaust gases with double-walled Insulon Hoses. May also be used to route cables and wires in high temperature environments.

Steam transfer

Improve safety in high temperature, high pressure steam transfer applications in food production and other industries with lightweight, flexible Insulon Hoses.

Other applications

Insulon Hose is engineered for fluid transfer systems from -270 to 900 C (-454 to 1652 F).
