rotary joints have been successfully used under variety of service conditions covering a wide range of materials,pressures,temperatures and speed. Pearl Rotary Joints are used for supplying/discharging compressed or decompressed fluid/gas from a fixed piping to the rotary section of various machines with no leak.
