About Rotating Joints
Rotating joints transfer hot and cold materials from your supply line to a continuously revolving drum, roller, or other rotating equipment.
Pipe size is an industry designation, not the actual size. View information about how to measure pipe size threads.

Iron and Steel One-Way-Flow Rotating Joints
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.

Use these rotating joints to transfer high-temperature materials from your supply line. They have a rotating shaft with threads on one end that connect to a continuously revolving drum, roller, or other rotating equipment. 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.

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. They are for two-way flow and are meant to be used when you need the supply line and the return line to be on the same side of your equipment. Joints are stainless steel for excellent resistance to corrosion caused by fluid flowing through them.
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.
