About Rotating Joints
Rotating joints transfer hot and cold materials from your supply line to a continuously revolving drum, roller, or other rotating equipment.

Thick-Wall Plastic Pipe Fittings for Water
Connect these fittings to Schedule 80 pipe–they have thicker, stronger walls than standard-wall fittings so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Fittings are plastic for good corrosion resistance. They meet ASTM specifications and testing requirements for material quality.
Fittings for drinking water meet NSF/ANSI Standard 61.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

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.

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.
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.

Expansion Joints with Butt-Weld Ends
- For Use With: Air, Natural Gas, Oil, Steam, Water
- Temperature Range: -20° to 800° F
- Maximum Pressure: 150 psi @ 72° F
- Maximum Vacuum: 29 in. of Hg @ 72° F
These joints weld to unthreaded pipe or another butt-weld fitting for a leak-resistant, permanent connection. They reduce stress, vibration, and noise in metal piping systems by providing a point of flexibility to absorb movement.
