Product Description
The Insulon® Low Pressure Insulated Hoses are vacuum jacketed hoses for gas or liquid transfer. These hoses utilize a proprietary insulation technology suitable for both cryogenic and high temperatures.
Applications
- Aerospace,
- Automotive,
- Cable & Wire Harnesses,
- Chemical Processing,
- Cleanroom Manufacturing,
- Cryogenic Fluid Transfer,
- Cryotherapy Devices,
- Food-Grade Applications,
- Fuel & Oil Lines.
Features
- Cleanroom-compatible materials (316L stainless steel),
- Compatible with cryogenic fluids including hydrogen, LN2, many others,
- Durable, reliable construction,
- Easy to install, clean and sterilize,
- Improve thermal energy efficiency,
- Low spring back reduces stress on connections and joints,
- Maintain safer external surface temperature,
- Minimize heat loss and conserve thermal energy,
- Naturally flame-retardant materials,
- Non-fibrous materials,
- Reduce condensation, dripping, and risk of mold,
- Reduce cryogenic material losses due to boil-off,
- Reduce risk of corrosion-under-insulation (CUI).
Specifications
- Thermal Range: -270°C to 900°C (-454°F to 1652°F),
- Jacket material: 316L Stainless Steel,

| Tube Stub Thickness (in) | 0.035 | 0.049 | ||
| Min. Tube Stub ID (in) | 0.180 | 0.430 | 0.680 | 0.902 |
- Pressure tests are conducted at 1.5x MAWP according to NAHAD Corrugated Metal Hose Assembly Specification Guidelines, p. 33 (2005).
- Insulation “touch temperature” performance for 6ft Length Hose:
- Cryogenic Performance: For LN2 (at -196°C) the hose jacket temperature was over 9°C, for temperature difference (∆T) of >205°C (369°F) warmer.
- High Temperature Performance: For hot air (at 900°C (1652°F) the hose jacket temperature maintained under 260°C (482°F), for temperature difference (∆T) of >205°C (369°F) cooler.
- This chart illustrates the difference between the media temperature (hot air) and the outer surface temperature (aka “touch temperature”). When the process media was 900°C (1652°F), the temperature difference was over 640°C (1150°F) at steady state.
- Insulation Reliability with Thermal Cycling:
- >20,000 cycles at 450°C without drop in insulation performance.
- Cycle was defined as a 3-minute ramp up during which the component reaches steady-state, followed by a 2-minute cool-down period. Ambient temperature was 23°C.
