Techflex Cryogenic Transfer Hose

The performance you want, with the safety you need.

Technifab’s Techflex vacuum insulated cryogenic transfer hoses are used in applications requiring the safe and efficient transfer of liquid nitrogen or other cryogens. Anywhere that cryogenic liquids are used in processing, our Techflex vacuum jacketed transfer hoses can ensure the highest quality liquid is delivered to the use point.



  • The most thermally efficient cryogenic transfer hoses available, Techflex reduces cryogen losses.

  • Lightweight, thin walled construction reduces liquid nitrogen cool down losses.

  • Higher quality liquid with lower gas content at the point of use improves equipment efficiency.

  • Rapid hose cool down reduces cooling time and speeds liquid cryogen delivery to the use point.

  • Hazardous ice & dripping water is reduced or eliminated, increasing safety.

  • Outer surface is safe to the touch, even when used with liquid hydrogen or liquid helium.

  • Interlocking stainless steel cover provides a light weight, durable, and flexible product.

  • Each transfer hose is flow and leak tested to ensure superior quality.

  • Standard lengths and end fittings are maintained in-stock for quick delivery.

  • Custom configurations are also available.
