Rod Buffer seals are secondary hydraulic rod seals used in tandem with the main rod seal to improve system reliability under dynamic pressure conditions. The Rod Buffer is designed to absorb pressure peaks, reduce pressure shock on the primary rod seal, and provide additional safety against extrusion and leakage in demanding hydraulic applications.
Sealing ring: PU (TPU)
Back-up ring: Thermoplastic (typically POM)
This two-piece design combines PU sealing performance with a rigid back-up ring to handle peak-pressure events and protect the primary seal.
Pressure (max): 400 bar
Temperature range: –35 °C to +110 °C
Sliding speed (max): 0.5 m/s
Installed behind the main rod seal in hydraulic cylinders for mobile and industrial equipment where pressure spikes and variable loads can accelerate wear on the primary seal.
