2" x 20' Cryogenic Transfer Hose — 280 PSIG CL 150

What pressure, flow and temperature is it rated for?

This hose is rated for 280 PSIG maximum working pressure with Class 150 flange connections. The listing does not specify flow capacity or minimum/maximum temperature ratings—ask the seller for the manufacturer's specification sheet showing cryogenic temperature range and flow coefficient. Cryogenic transfer hoses are typically rated from -320°F (LN2 service) up to ambient, but the actual range depends on the inner liner and insulation materials used.

What materials are the wetted parts?

The listing does not identify the inner liner material, annular space insulation, or flange/fitting metallurgy. Request the manufacturer's material certificate or construction specification showing inner tube material (typically corrugated stainless or PTFE), outer jacket, insulation type (vacuum, foam, or perlite), and flange material (304SS, 316SS, or other). Material selection determines both gas compatibility and thermal performance.

What should I inspect before putting it into service?

Since this hose is listed as new, verify the vacuum integrity if it's a vacuum-jacketed design (poor vacuum dramatically reduces insulation performance), and pressure test the inner line per your facility procedures or CGA standards. Inspect both flange faces and gasket seating surfaces for damage from storage or shipping, check that flange bolt holes align with your mating equipment, and confirm gasket material is appropriate for your cryogen. Even new hoses should be leak-checked at operating pressure before filling with cryogenic liquid.
