Carbon Dioxide Hose

Carbon dioxide hose or CO2 hose is used to transfer both liquid and gaseous CO2. Carbon dioxide is a solid below -109 Deg. F. and becomes a gas at temperature above that figure. It can exist as a liquid only at temperatures between -70 Deg. F. and +75 Deg. F. Liquid CO2 takes up vastly less space than it does in its gaseous state and has become the ideal way to store large quantities for use in many industries. CO2 has numerous uses, including being a additive in the beverage industry. 

Unisource CO2 hose is manufactured in 1/2-inch in size and is made with thermoplastic material that is rated both for FDA grade food product, and also for the low temperatures that will be encountered. Hose construction is formulated to be unaffected by the possible degrading effects of CO2 and to handle pressure spikes that are encountered in many applications. The main installations for carbon dioxide hose are 1) as a fill hose stored on a delivery truck in long lengths on a hose reel, and 2) as a hose transporting liquid CO2 between the fill box at a customer facility and a liquid storage vessel. The hoses are used in lengths that vary from five feet long to 100 feet long. They are used an an assembly with metal hose fittings and paired with an equal length of translucent vent hose to provide safe outdoor venting.

In this industry, CO2 applications are heavily monitored by the FDA and the manufacturing and safety recommendations of the CGA. Unisource is a member of the Compressed Gas Association (CGA), the leading organization for the development of safety standards in the gas industry.

Carbon Dioxide Liquid/Vapor Transfer Hose

Series 4770 Beverage CO2 Fill Hose

Series 4770 thermoplastic hose is specifically designed for the transfer of liquid and gaseous carbon dioxide (Co2) for beverage applications. It is commonly used on squirt-truck delivery reels as well as flexible lines from the restaurant wall-box to the liquid cylinders. Series 4770 hose is specifically formulated to perform well in temperatures as low as -40 Deg. F., and the proprietary core is plasticiizer-free and FDA compiant. Our unique bonding process guarantees excellent kink resistance, and the proprietary “Tuff-Skin” cover provides for superior handling and abrasion resistance.
