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.

How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

About U-Joints (Universal Joints)

U-joints are used to connect two shafts that have a high amount of misalignment.

These snaps have an eye that rotates for easy positioning.

Zinc-plated snaps are mildly corrosion resistant.

Brass and nickel-plated snaps are more corrosion resistant than zinc-plated snaps.

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.
