NDL Industries

We started in 1987 as a mechanical engineering firm, consulting the refrigeration industry in Canada, the U.S., Australia, and New Zealand. Then in 1998, our engineers recognized a need for a more complete ACR fitting as new refrigerants emerged. Our focus began to shift from consulting to production, with the result being an elite ACR copper fitting like no other in the industry.

We offer a 10-year warranty on our ACR copper fittings, even though we've never had a reported failure. After producing our ACR copper fittings, we expanded our HVAC-R selection to include refrigeration ball valves, filter driers, P/AC copper fittings, and sight glasses. Building off the success we gained from our HVAC-R product selection, we started producing plumbing products including copper press fittings, plumbing valves, and brass/ppsu PEX fittings. We now over HVAC-R and Plumbing products in over 23 product categories to cater to the industry's needs.

Now we have a heavy focus on our CO2 refrigeration products which include CO2 valves and copper fittings. Our CRN-approved and UL-listed CO2 ball valves and check valves hold five times the maximum working pressure, netting a tremendous safety margin for any valve used in a CO2 system. These valves are paired with our selection of UL-listed CO2 copper fittings (C19400 high-pressure copper) specifically designed for use in CO2 refrigeration and HVAC systems.

Our latest innovation solution within the CO2 refrigeration industry is our CO2 service tee, meticulously crafted to not only streamline operations but also optimize cost-effectiveness, ultimately saving you valuable time and resources. Some advantages of regular fittings are:

• Fewer parts used
• Fewer operations are required to install the service valve
• Reduces the amount of possible leakage points
• Perfect fit, no need to drill or expand fittings
