Buffer Seals

Molded with a premium urethane and employing a back-up, this seal absorbs the shock of pressure spikes to protect the rod seal. The unique design also relieves back pressure between the buffer and the rod seal. The premium urethane demonstrates good heat resistance with almost no permanent deformation at high temperatures. In addition, the elastomeric properties can be quickly restored even in low temperatures to ensure stable sealing in cold applications.

The RBS style rod buffer seals are a rectangular urethane buffer ring designed to absorb pressure fluctuations to protect the primary rod seal. Some sizes include a radial and axial slot, which faces the pressure, to relieve back pressure between the primary and buffer seal. This simple design is commonly found on older construction equipment.
