Question

Quizplus · Accepted Answer

ACR stands for "Air Conditioning and Refrigeration" and typically refers to copper pipe used in HVAC systems. The size 5/8" ACR refers to the outside diameter of the pipe. Therefore, the technician should ask for 1/2" ID (inside diameter) copper pipe, which has an outside diameter of 5/8". Neither PVC nor a different size of copper pipe will be suitable for this application.
