Buffer seal protect the rod seals by reducing the magnitude of
pressure peaks. Abrupt pressure peaks can occur by external forces
acting on the piston rod, initiated by the fluid inside the
cylinder. These pressure peaks can be far in excess of the system
operating pressure. Buffer seals in combination with rod seals
provide an effective rod sealing system for cylinders in heavy duty
applications at high temperature and pressure.
