PressACR is a copper press connection system designed to meet the demands of refrigeration systems. PressACR utilizes a gray HNBR sealing element to provide permanent leak-proof connections. PressACR is approved for use with K, L & M hard copper tubing and soft copper tubing in 1/4” through 7/8” OD diameters. PressACR is only approved for use with K, L & M hard copper tubing for sizes 1 1/8” and above. All tubing must comply with ASTM B280 ACR tube or B88 standards. PressACR fittings are approved for air conditioning and refrigeration applications using A class refrigerants.
