Buffer Seals
Depending on the application, a rod sealing system can consist of a rod seal and a buffer seal or only a rod seal. The main types of rod buffer seals are lip seals with back-up rings, lip seals without back-up rings, and o-ring energized glide ring seals. Buffer seals help absorb pressure spikes that occur in heavy-duty cylinders to protect the primary rod seals.
