About us

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’ve continued to expand our product selection, currently offering Refrigeration Ball Valves, Filter Driers, Gas Flex Connectors, CO2 Ball Valves/Fittings, and more. Building off the success gained from our HVAC-R products, we have grown our plumbing products to include PAC Fittings, which are ASME approved. Our Plumbing selection includes Copper Press Fittings, Plumbing (WOG) Valves, Brass/PPSU PEX Fittings, DWV/SCH40 PVC Fittings, Water Hose Connectors, and more. Now at NDL, we manufacture HVAC-R and Plumbing products across 23 categories that outperform the industry standards, so we always have what you need.

There is an increasing number of trading companies that import fittings at an attractive price, but those companies have no control over the quality, standard, and capabilities of the product they import. Since we place a high emphasis on quality and service, our fittings are manufactured to exceed and outperform any other fitting in the industry. Our customers have come to expect a certain level of quality and service from our HVAC-R and Plumbing products, which is why it is our mission to strive to exceed those standards, and be an industry leader.

Our 10-Year Ultimate Protection Warranty for our ACR Copper Fittings provides our customers with peace of mind, but we’ve never had a reported product failure which is a testament to the fact that we’ll never sacrifice the quality of our product. We also offer industry-leading valves, engineered to offer the best performance. We test them at 100% before leaving the factory while also offering a 2-Year Warranty on them, so our customers can be confident in our product. Along with the specific warranties we offer on our ACR Copper Fittings, and Valves, we offer a 1-Year Limited Warranty on the rest of our products.
