Cryogenic Transfer Hose — 20' 1-1/2" x 2" CL 300/150

What pressure, flow and temperature is it rated for?

This hose is rated for 280 PSIG. Flow capacity depends on the actual inner diameter of the corrugated core and acceptable pressure drop for your application; cryogenic hoses in this size class typically handle 50-150 GPM for liquid nitrogen or oxygen service. Temperature rating is not stated in the listing—ask the seller for the minimum design temperature and whether it's rated for full vacuum, as these are critical for cryogenic transfer applications.

What should I inspect before putting it into service?

Verify end fitting torque, inspect both flanges and sealing faces for damage or contamination, and confirm the hose shows no kinks, flat spots, or damage to the outer jacket or braid. Pressure test to your facility standard (typically 1.5x operating pressure with nitrogen), perform a leak check at operating pressure, and functionally test any vacuum jacket if present. Even though listed as new, verify it has been properly stored—prolonged storage can degrade seals and vacuum integrity.
