Buffer Seals

Buffer seals are used to protect the rod seal from pressure spikes.  A buffer seal's design incorporates channels that allow fluid to flow around the buffer seal under normal operating conditions.  In the event of a surge in hydraulic pressure, these channels bottleneck the applied pressure and prevents the spike from reaching the rod seal.
