The Rotary (M.C.T.) Union is mainly intended for use on machine tools for the transfer of fluids (such as oil and air) to and from rotating shafts for air and hydraulic chucks, brakes, clutches, etc.
The type of Rotary Seal fitted to the Rotary (M.C.T.) Union is a “FILTON BALANCED MECHANICAL SEAL”, containing multiple helical coil springs. The seal face materials are normally carbon against stainless steel. For applications on machine tool coolants where traces of abrasive particles may be present we recommend tungsten carbide seals. If required add code T.C. to the part number.
