ROTARY UNION R/RH

The RH union is most frequently used with hot water or thermal oil for heating cilinders. It is available in single and dual passage versions with rotating or stationairy syphons. This will allow for inlet and outlet of the fluid to be on the same side of the machine.

The union can be threaded or is available with flanged connections. This depends on the application and local requirements of the application.

Johnson-Fluiten suppliers different seal materials, body materials, o-rings for the different applications. Also we supply ATEX certifications for our unions on request.
