CO2 Refrigeration Products

We are the manufacturer of the first CRN-approved ball valve for transcritical CO2, which can hold five times its maximum working pressure, netting a tremendous safety margin for any ball valve used in CO2 systems. Along with CO2 valves, NDL offers CO2 copper fittings (C19400 high-pressure) that are specifically designed for use in CO2 refrigeration systems. Also, NDL offers CO2 copper tees specifically designed for easy installation of service valves. Whether it’s valves or fittings, NDL is here to fit your CO2 needs.
