These joints have a rotating shaft with threads on one end that connect to a continuously revolving drum, roller, or other rotating equipment. Use them to transfer hot and cold materials from your supply line. Joints are for one-way flow and are meant to be used in pairs—one joint serves as the supply line while the other serves as the return line.

If your drum rotates counterclockwise as you face the connecting end, you should select a rotating joint with right-handed threads. If your drum rotates clockwise as you face the connecting end, you should select a rotating joint with left-handed threads.
