CO2 Copper Fittings

The NDL CO2 copper fittings (C19400 high-pressure copper) are specifically designed for use in CO2 refrigeration and HVAC systems.

  • Exceeding Design Expectations
    Our high-pressure copper-iron alloy fittings are tested for actual burst pressure with the results exceeding 3 times the design pressure.
  • Enhanced Strength Material
    These fittings are made from a high-quality copper alloy that provides added strength and durability.
  • High-pressure Reliability
    The unique design of these fittings allows for a secure and long-lasting connection, making them ideal for use in high-pressure applications.
  • Stronger Joint Integrity
    The fittings have tight tolerances on the cup side for a stronger joint with the tube and easier brazing
  • Easily Identifiable
    Each fitting is marked with “CO2 130 BAR” and OD size for easy field identification.
  • Clean Packaging
    Fittings are poly-bagged within the box, keeping them clean and contaminant-free before installation.
