CGA 320 is the standard connection fitting for Carbon Dioxide (CO2) cylinders in North America. It requires a washer to seal.
Typically, washers are sold separately or supplied with the cylinder, but it is always good practice to have spare CGA 320 washers on hand as they are single-use items.
JIC stands for Joint Industry Council. It refers to a fitting with a 37-degree flare seating surface, commonly used in high-pressure hydraulic and industrial systems for a leak-tight metal-to-metal seal.
The stainless steel braid prevents the hose from expanding under pressure, protects it from physical damage like cuts and abrasion, and keeps it flexible at cryogenic temperatures.
No. Argon uses CGA 580 and Oxygen uses CGA 540. This hose is specifically fitted with CGA 320 for Carbon Dioxide. Using adapters is possible but using the correct hose for the gas service is safer.
Yes, this is a cryogenic-rated hose designed to withstand the low temperatures of liquid CO2 transfer without becoming brittle.
The JIC fitting has a swivel nut. You should hold the hose body steady and tighten the nut onto the male flare fitting. It seals on the flare, so do not use Teflon tape on the threads.
While specific ratings depend on the manufacturer, stainless steel braided cryogenic hoses of this size are typically rated for working pressures exceeding 3000 PSI, suitable for full cylinder pressure.
