Hot Oil Rotary Union

In industrial heating and thermal fluid systems, maintaining stable, leak-free hot oil transfer under continuous rotation is critical. Our rotary unions for hot oil are specifically engineered to operate under high temperature, high viscosity, and demanding pressure conditions, ensuring safe and efficient performance.

This tag page aggregates a full range of thermal oil rotary joints, designed for industries such as steel processing, chemical production, plastics, and paper manufacturing.

What Are Rotary Unions for Hot Oil?

A hot oil rotary union is a precision mechanical device that allows thermal oil (heat transfer fluid) to pass from a stationary pipeline into a rotating component, such as a heated drum, roll, or reactor.

These systems typically operate under:

  • High temperatures (up to 300°C or higher)
  • Continuous rotation
  • High viscosity fluids

This makes sealing performance and material stability absolutely critical.
