  • 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.
