Recently, our ACR Copper Fittings have received UL Certification and got 1000 PSI Working Pressure and a maximum abnormal pressure of 1500 PSI. This applies to our ACR Copper Fittings that are up to and including 7/8″ size.

• ASME Standards
  NDL ensures copper quality content and strict adherence to meet or exceed ASME B16.22 standards for wall thickness.
• Brazing Made Simple
  The fittings have tight tolerances on the cup side for a stronger joint with the tube and easier brazing.
• Easily Identifiable
  NDL stamps the size on each fitting. This greatly benefits the counter sales team, ensuring correct identification. It also aids the contractor in the field once the fitting is removed from the box.
• Poly-Bagged and Clean
  NDL poly-bags the fittings before packaging them inside the box. It is important to the refrigeration system to keep the fittings clean; contaminants can cause expensive and destructive malfunctions. This organizational feature also saves time and money when clients count their inventory, they count boxes and not individual fittings.
• Unparalleled Ten-Year Warranty
  The unparalleled NDL 10 Year Ultimate Protection Warranty will cover the loss of refrigerant and labor to replace the failed fitting. But copper fittings have zero reported failures since 1999, so there’ s not much to worry about there.
