HBY - BUFFER SEAL
The HBY buffer seal is a heavy-duty hydraulic rod seal designed to protect primary rod seals from shock pressures, high temperatures, and pressure spikes in cylinder applications. It features a U-cup shape combined with an anti-extrusion ring, commonly made from polyurethane (PU) and polyacetal (POM), ensuring high wear resistance.
