Multi-passage rotary union line for power, fluid, and data transfer feature standard configurations designed to meet the needs of the most common industrial and commercial applications requiring a rotary sealing device with 2 to 12 passages.

Multi-passage rotary unions provide sets of seals between stationary connections and rotating equipment, such as a drum, index table, clutch, or spindle.

The multiple, independent passages permit the flow of the same or different media into and out of rotating equipment. In most cases, each passage requires isolation from other passages, especially when the different media cannot mix, or they operate under different pressures.

Features:

• Flow Passages: 2 to 12
• Media Types: Air, Coolant, Oil, Steam, Water
• Passage Sizes: 1/3, 1/4, 3/8, 1/2 in
• Connection Type: NPT, BSPT, G/BSP (ISO 228), O-ring
• Pressure (Max): 5,000 psi (345 bar)
• Temperature (Max): 220ºF (105ºC)
• Speed (Max): 500 RPM
• Material Type: Steel, Stainless Steel, Aluminum, Brass
