1-1/2" x 20' Cryogenic Transfer Hose — CL300 connections

What pressure, flow and temperature is it rated for?

This hose is rated for 570 PSIG maximum pressure. Flow capacity is not stated in the listing; ask the seller for the CV or flow coefficient data, which will depend on the corrugated inner core design. Cryogenic hoses in this category are typically rated to -320°F for LNG service, but the specific minimum temperature rating is not provided—request the manufacturer's specification sheet.

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

The listing specifies suitability for LNG and other cryogenic fluids. Oxygen cleaning status is not stated. If you intend to use this for oxygen service, ask the seller for documentation confirming CGA G-4.1 cleaning and whether it has been bagged and sealed to maintain cleanliness.

What should I inspect before putting it into service?

Visually inspect the entire length for kinks, dents, or damage to the outer jacket and check both end connections for dings or thread damage. Pressure test the assembly with nitrogen and hold for leak detection, checking especially at the crimped or welded end fittings. Verify flexibility by flexing the hose through its intended bend radius—cryogenic hoses can become stiff or develop microcracks in the corrugations if stored improperly even when new.
