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

What pressure, flow and temperature is it rated for?

This hose is rated for 280 PSIG. Flow capacity depends on the internal corrugation design and insulation type, neither of which is specified in the listing—ask the seller for the manufacturer's flow curve or nameplate data. Cryogenic hoses are typically rated for service down to liquid nitrogen temperatures (-320°F), but the actual minimum temperature rating for this unit is not provided.

What materials are the wetted parts?

The listing does not identify the inner liner material, outer jacket, or end connection metallurgy. Typical cryogenic hose construction uses corrugated stainless steel inner tubes with vacuum or powder insulation and stainless steel flanges, but you'll need the manufacturer nameplate or specification sheet to confirm the actual materials in this assembly.

What should I inspect before putting it into service?

Examine the corrugated inner tube for cracks, kinks, or flat spots that compromise flow or structural integrity, and check the insulation jacket for tears or moisture ingress that would degrade thermal performance. Verify the end connections for flange face damage, bolt hole integrity, and proper gasket seating, and pressure test the assembly to the rated 280 PSIG before cryogenic service. If the hose has been in storage, check for vacuum loss in vacuum-insulated models and verify flexibility—hoses that have been coiled too tightly or allowed to freeze with residual moisture may have permanent damage.
