Insulon Hose is the first of its kind — a vacuum jacketed hose engineered with proprietary insulation technology for cryogenic and high temperature environments. Insulon Hose is engineered for applications from -270 to 815°C (-454 to 1500°F).

Insulon Hose HP, 3/8″ ID has a maximum allowable working pressure (MAWP) of 750 psi for applications below 38°C fluid temperature. For high temperature applications, see pressure derating factor at temperature.

  • Cryogenic applications use vacuum insulated hoses to safely transfer extreme temperature fluids including liquid nitrogen, hydrogen, helium, argon, and oxygen.
  • High temperature fluid transfer systems use Insulon Hose to minimize heat loss for maximum thermal precision and control. Applications include process heaters, exhaust lines, steam lines, and deposition gases.

All Insulon Hose products are made-to-order and final sale.
