A multiple port rotary union looks like a perforated cylinder. Rotary unions also appear in automobiles and other machines that require constant supplies of lubrication, air, or other liquids in order for moving parts to run smoothly. Many assembly lines incorporate multiple rotary unions, because they are highly versatile and take up less space than other devices designed for a similar purpose.

The material being transferred flows into the cylinder and out of the input holes. The bearings are always used to allow a part of the joint, either the shaft or the housing, to rotate. The seal prevents the medium from leaking outside the rotary union while in operation. Seal types can vary from pusher-type end face mechanical seal, non-pusher type end face mechanical seal, lip seals, and o-ring seals.

Rotary unions are also heavily used in crude oil processing, the chemical industry, commercial food production, and pharmaceutical applications. Paper applications span the supply chain from the raw pulp and paper mills, to the downstream paper converters. Most rotary unions have more than one seal. A rotary union will lock onto an input valve while rotating to meet an outlet.
