DESCRIPTION

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. These are designated with a “SL” at the end of the part number.

This simple rod buffer design is commonly found on older construction equipment.
