ACR Copper Tubing: What It Is, And When, Where, and How It is Used
ACRCT is used in the Air Conditioning and Refrigeration Field Service Industry and is designated by the tube's actual OD.
Only hard drawn ACRCT is marked with color; annealed is not. It is used to hold various refrigerant mediums that make Air Conditioning possible in conjunction with refrigerant compressors and the rapid heat transfer rate made possible by the excellent heat conductivity of copper. Because internal pressures play a key role in ACR applications, working pressures recommended by the Copper Development Association in conjunction with the ASTM (American Society for Testing and Materials), which provides the report Standard Specification for Seamless Copper Tube, are repeated below for your convenience.
