3" x 20' Cryogenic Transfer Hose — CL300 x CL300 — 500 PSIG

What pressure, flow and temperature is it rated for?

This hose is rated for 500 PSIG. Flow capacity depends on the specific inner construction and corrugation profile, which are not specified in the listing—ask the seller for the Cv or flow curve data. Cryogenic hoses are typically rated for service down to -320°F for LN2 and LOX applications, though the exact minimum temperature rating should be confirmed with the manufacturer's documentation.

What should I inspect before putting it into service?

Since this is new with a 7-day lead time, verify flange bolt hole alignment, gasket seating surfaces for damage during shipping, and that the vacuum jacket (if present) holds vacuum per the manufacturer's spec. Pressure test the hose to your system requirements and confirm end fittings match your piping class—CL300 flanges should be verified for bolt pattern and raised-face or flat-face configuration. Check for any kinks or damage to the corrugated core and confirm you have the manufacturer's minimum bend radius specifications.
