Rotary Joint Unions | Development & Precision Machining

Rotary joints, rotary couplings, and rotary unions are used to cool, heat, or transfer fluid. Applications include the transfer of steam, water, hydraulic fluid, thermal oil, glycol, coolant, air and may also be used for vacuum. Our high quality rotary unions are used in for various industries such as machinery, marine shipbuilding, and power plant industries.


Whether you require a one passage or multiple-passage rotary joint, we are able to supply custom-made rotary unions for your specific applications. The advantage of having a multiple-rotary union is that it provides a convenient solution when you require the transfer of more than one type of fluid medium through a single rotary coupling. Some of the applications that we cover are rotary unions for tooling machine, automotive jigs, industrial machinery, and industrial plant. Since 2006, we have been designated as the exclusive supplier for rotary joint unions to Doosan Infracore’s turning centers and machining centers.
