RBS Rod Buffer Seals

The RBS style rod buffer seals are a rectangular urethane buffer ring designed to absorb pressure fluctuations thereby protecting 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.
