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: See table
- 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.

Brass One-Way-Flow Rotating Joints

- For Use With: Oil, Steam, Water
- Maximum Temperature: 250° F
- Maximum Pressure:
Oil: 100 psi @ 72° F
Steam: 15 psi @ 250° F
Water: 750 psi @ 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 brass for good corrosion resistance. For steam applications use intermittently (up to 20% of operating time).
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.

Male-Female Round Universal Thread Adapters with Through Hole




Connect male- and female-threaded parts of different thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through. Attach your parts to these adapters and use a hex key to secure the connection. Made of 304 stainless steel, all will hold up in wet environments. O-rings on each side create a tight seal, making them good for vacuum and compressed-air applications.

Male Round Universal Thread Adapters with Through Hole




Join two female-threaded parts of various thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through. Attach your parts to these adapters and use a hex key to secure the connection. Made of 304 stainless steel, all will hold up in wet environments. O-rings on each side create a tight seal, making them good for vacuum and compressed-air applications.
