Type 0 sealing ring is the simplest form of sealing ring for smaller hydraulic cylinders, and U-ring is used for larger hydraulic cylinders or heavy-duty applications. U-ring has been proved to be one of the most successful pressure seal rings (and suitable for piston seal rings) and is widely used.
