Rotary Union for Coolant

A Coolant Rotary Union, also known as a coolant swivel or rotary coupling, is a mechanical device designed to facilitate the transfer of coolant from a stationary source to a rotating component in machinery. Its primary function is to supply coolant—typically a liquid or gas—to moving parts, preventing overheating and ensuring optimal performance during operation.
These unions are engineered to handle high pressures and rotational speeds while maintaining a leak-free seal, which is crucial for the longevity of both the union and the machinery it serves.
