A swivel joint, also called a rotary joint or swivel joint, is a mechanical device used to transfer fluids, gases, or other materials between a stationary and rotating part of a system. It maintains a sealed connection while allowing continuous or intermittent rotation, preventing leaks and ensuring efficient operation.

Common applications include:

Fluid transfer: Liquids or gases (e.g., water, oil, air) flow between stationary and rotating parts in mechanical equipment such as hydraulic systems, cooling systems, or steam turbines.

Industries: Manufacturing, aerospace, automotive, robotics, and energy industries.

Key features:

Sealed passages to prevent leaks.

Bearings to ensure smooth rotation.

Made of materials such as stainless steel or brass for durability.

For example, in a car wash system, a swivel joint allows water to flow from a stationary pump to a rotating spray arm.
