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.

Aluminum One-Way-Flow Rotating Joints

- For Use With: Air, Hydraulic Oil
- Temperature Range: -20° to 250° F
- Maximum Pressure:
Air: 150 psi @ 72° F
Oil: See table - Maximum Vacuum: 28 in. of Hg @ 72° F
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. Joints are made of lightweight aluminum. They are a compact size for use in small air and hydraulic applications.
If your drum rotates counterclockwise as you face the connecting end, you should select a rotating joint with right-handed threads.
