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