ACR Copper Tube is designated by the tube’s actual OD.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).
