Applications
Insulon® Hose LP is engineered specifically for atmospheric and lower pressure applications. Download the data sheet for more details. If you need vacuum jacketed hoses for a high pressure application, please submit a custom tubing request form.
Cryogenic Fluid Transfer
Insulon Hose LP is designed for the transfer of liquid nitrogen and other cryogenic fluids
High Temp Liquids & Gases
Insulon Hose LP features vacuum insulation that can be used at high temperatures
Chemical Processing
Maintain materials at precise temperatures in chemical and petrochemical processing
Cable & Wire Harnesses
Cable and wire harnesses in high temperature environments need thermal insulation
Industrial Equipment
Insulon Hose LP is rugged and durable, well-suited to demanding industrial applications
Thermal Insulation Performance
Insulon Hose LP is designed for cryogenic and high temperature environments from -270°C to 900°C (-454°F to 1652°F). The charts below illustrate the thermal performance of a 1/2″ ID, 6-foot long Insulon Hose LP. The first chart highlights cryogenic insulation performance; the second chart highlights high-temperature insulation performance.

Features & Benefits
Thermal Insulation
Thermal energy is valuable. Insulon Hose LP is designed with advanced vacuum insulation to help you conserve this valuable resource. Save energy, reduce heat waste, and improve overall efficiency. Download the data sheet to view cryogenic and high-temperature insulation performance data.
Flexibility with Low Springback
Insulon Hose LP provides flexibility with low springback for reduced stress on connections, fittings, and joints. Download the data sheet for technical specifications including static bend radius.
Flame Retardant Materials
Insulon Hose LP is built with 316L stainless steel, a naturally flame-retardant material. Insulon Hose LP is engineered for thermal environments from -270°C to 900°C (-454°F to 1650°F). If you need vacuum jacketed tubing for higher temperature applications, please fill out our custom tubing request form.
Non-Fibrous Insulation
Fibrous insulation materials can be cumbersome to install, inspect, and maintain. They can become compressed over time, reducing their effectiveness as an insulator. They can also release fibers, causing problems with contamination and inhalation. Insulon Hose LP provides a non-fibrous insulation solution for cleanrooms and other sanitary environments.
Reduce Condensation
Proper thermal insulation helps reduce condensation on the outer surface of the hose. By limiting the accumulation of moisture, Insulon Hose LP helps prevent dripping, frost, corrosion, and the risk of mold growth.
