*Insulators for both the Suction tube and the Discharge tube are the same.
*Suction tube and Discharge tube are similar in sizes and both the tube entrances have the same diameter. So the both
Distribution joints can fit into different tubes. Since the diameter of the tube ends for both Suction and Discharge tube are
different, take care not to connect the distribution joint different. See the " # " marks on the above figures.
