Stainless Steel One-Way-Flow Rotating Joints
- For Use With: Air, Oil, Steam, Water
- Maximum Temperature:
Oil: 390° F
Steam: 350° F
Water: 300° F - Maximum Pressure:
Air: 300 psi @ 72° F
Oil: 100 psi @ 72° F
Steam: 120 psi @ 350° F
Water: 750 psi @ 72° F - Maximum Vacuum: 25 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 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.

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.
