Chart Cryogenic Transfer Hose

What pressure, flow and temperature is it rated for?

This hose is rated for 250 PSIG at 70°F. Flow capacity is not specified in the listing; ask the seller for the CV value or nominal flow rate at your operating pressure differential. Cryogenic hoses in this class typically see significant pressure drop over short lengths due to corrugated inner construction, so confirm actual flow performance against your transfer requirements.

What gases is it compatible with, and has it been oxygen cleaned?

The listing specifies LNG fill connections, indicating this unit is configured for liquefied natural gas service. Chart Flex-Pression hoses are generally suitable for LNG, LIN, LOX, and LAR, but compatibility depends on material selection and end fittings—verify with the seller if you're transferring oxygen or other reactive gases. Oxygen cleaning status is not stated; ask the seller for cleaning certification if required for your application.

What should I inspect before putting it into service?

Inspect both end connections for thread damage, proper gasket seating surfaces, and any signs of impact or dropped hardware. Check the outer jacket for dents, punctures, or loss of vacuum (frost patterns or abnormal flexibility indicate compromised insulation), and flex the hose gently to detect any kinks or stiff sections in the corrugated core. Pressure test per your facility requirements before introducing cryogen, and verify the hose has not exceeded shelf life limits on vacuum integrity even though it is listed as new.
