Insulon® Vacuum Jacketed Hose, High Pressure, Standard, 1/4″ ID

Insulon® Vacuum Jacketed Hose, High Pressure, Standard, 1/4″ ID. Standard vacuum insulation maintains a high-vacuum annulus between the inner corrugated bore tube and the outer jacket, eliminating convection and conduction heat transfer. Delivers exceptional thermal performance in the most compact, low-profile form factor in the Insulon® hose product line. Recommended for: most cryogenic transfer applications, chiller fluids to -80°C, transient cryogenic flow (seconds/minutes), liquid CO2, and applications where minimal outer diameter is required. High Pressure Insulon® hose rated to 750 psi at RT (≤100°F / 38°C). MAWP decreases as fluid temperature increases above 100°F; see derating table below. Typical applications: high-pressure cryogenic transfer, propulsion test stands, industrial process lines, hydrogen service at elevated pressures, liquid hydrogen aerospace propellant lines. Compatible Fluids for Insulon® Vacuum Jacketed Hose Cryogenic liquids: liquid nitrogen (LN2), liquid helium (LHe), liquid argon (LAr), liquid oxygen (LOX), liquid natural gas / liquid methane (LNG / LCH4), liquid CO2 Hydrogen: liquid hydrogen (LH2) and gaseous hydrogen (GH2). Fully annealed materials resist hydrogen embrittlement. Thermal fluids and coolants: glycol/water mixtures, Syltherm 800, Syltherm XLT, Dowtherm Q, Dowtherm J, other synthetic heat transfer fluids, cryo-chiller fluids High-temperature fluids: steam, hot air, exhaust gases, process heating oils Specialty and process gases: GN2, GHe, GAr; semiconductor precursor, carrier, and deposition gases Corrosive media: add a fluoropolymer liner (PTFE, PFA, FEP) for broad compatibility with corrosive process fluids If system pressure at operating temperature exceeds MAWP, contact Concept Group engineering. Insulon® Hose MAWP by Fluid Temperature, 1/4″ ID, High Pressure MAWP is constant from cryogenic temperatures through room temperature (≤100°F / 38°C). For fluid temperatures above 100°F, use the derating table below. Round UP to the next 100°F row for conservatism (e.g., a 320°F system uses the 400°F row).
