To determine the size of a JIC fitting, measure the outside diameter of the male thread or the inside diameter of the female thread using calipers. Then, refer to a JIC size chart to match the measurement to the corresponding JIC size, which is typically given in sixteenths of an inch (e.g., a 3/4-inch outside diameter corresponds to a -12 JIC size).
