4" x 20' Cryogenic Transfer Hose — CL300 450 PSIG

What pressure, flow and temperature is it rated for?

This hose is rated for 450 PSIG with CL300 flanged connections. The listing does not specify temperature range or flow capacity; ask the seller for the minimum design metal temperature (MDMT) and whether it meets the -320°F service typical for LNG. Cryogenic hoses in this size typically handle flows of 200-400 GPM depending on pressure drop limitations and fluid properties.

What should I inspect before putting it into service?

Since this is listed as new, verify that flange faces are undamaged, gasket surfaces are clean, and protective end caps have remained in place during storage. Pressure test the hose per your facility procedures before introduction to cryogenic service, and inspect the outer jacket for any shipping damage or abrasion. Check that the hose has not been kinked or bent beyond its minimum bend radius, and verify that all certifications and traceability documentation are included.
