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 inner corrugation design and whether it's a vacuum-jacketed or foam-insulated construction, which the listing does not specify—ask the seller for the actual flow curve or CV data. Cryogenic hoses in this category are typically rated down to -320°F for LN2 service, though the exact minimum temperature rating for this unit is not stated.

What should I inspect before putting it into service?

Visually inspect both CL300 flanges for damage, verify all bolts and gaskets are present and undamaged, and check the outer jacket for cuts, abrasions, or signs of moisture intrusion if vacuum-jacketed. Pressure-test the hose to your facility's acceptance criteria—typically 1.5x the operating pressure with nitrogen—and verify flexibility by gently flexing to ensure the corrugated core has not been kinked during storage. If used for oxygen, confirm cleaning certifications are current and that no contamination has occurred during storage.
