The first measurement, liquid line diameter is available in 1/4, 3/8 or 5/8 inches, and the suction line, the second measurement is available as 1/2, 3/8, 5/8 or 3/4 inches depending on the size and efficiency of the air conditioner or heat pump. The last measurement is the length, which is available in differing sizes.
