Rotary joints are widely used in a variety of materials, viscosity, temperature, pressure  and speed. Rotating joints can withstand very high pressures while rotating at high speeds.  To do this, the sealing surfaces must be nearly perfectly matched. The seal must be tightly  fitted and can rotate smoothly and steadily and minimize friction to extend service life and  ensure no leakage.
