ACR Copper Fittings

NDL proudly leads the industry with its flagship ACR Copper Fittings. These fittings not only meet but exceed industry standards for working pressure. As a result, they are trusted for their precision and reliability. Consequently, they set the benchmark for quality in HVAC-R systems.

• Exceptional Copper Quality
  NDL ensures exceptional copper quality. Our fittings are carefully built to meet ASME B16.22 standards for wall thickness. Therefore, you can trust that each fitting is both durable and long-lasting. In turn, this guarantees performance that goes beyond expectations.
• Superior Burst Pressure
  Our ACR copper fittings undergo rigorous testing. They are approved by TSSA with a safety margin 4.5 times higher than required. Consequently, they can handle up to 60 bar for sizes 1-3/8″ and below. This makes them ideal for high-pressure applications.
• Precise Tolerances for Better Connections
  The NDL fittings feature tight tolerances. As a result, the joint with the tube becomes stronger. This feature also facilitates easier and more efficient brazing, which leads to contractors being able to install the fittings faster and with greater reliability.
• Easily Identifiable
  Each fitting is clearly stamped with its size for easy identification. This simple detail helps sales teams quickly find the correct part. Moreover, it benefits contractors in the field, especially when fittings are removed from their packaging.
• Clean and Organized Packaging
  We take extra steps to ensure that our fittings remain clean. Each fitting is sealed in a poly bag before being packed in a box. This prevents contamination that could cause costly system malfunctions. Furthermore, the packaging system simplifies inventory checks. Clients can count boxes instead of individual fittings, saving both time and effort.
• Unparalleled Warranty
  We stand behind our products with a 10-Year Ultimate Protection Warranty. This warranty covers refrigerant loss and labor costs for replacing any failed fitting. Remarkably, there have been zero reported failures since 1999. Therefore, you can trust that NDL copper fittings are both reliable and long-lasting.
