25 Years ago NDL began as an engineering company consulting to the HVAC/R industry in Western Canada. In 1998 NDL began manufacturing a heavy walled ACR copper fitting because main brand copper fittings continued to get thinner. In 2012 NDL developed the P/AC copper fitting line to give clients an option of a more modest priced fitting that still maintained high quality. This line allowed clients to be competitive with less expensive import companies that did not control production and quality.
NDL is the only company with two distinct lines of copper fittings, a premium thick walled ACR fitting, and a P/AC fitting that is more modestly priced, that still exceeds industry standards. NDL ball valves use advanced engineering and materials to reduce leak risk. NDL wants the customer to be better by allowing us to partner with them.
