This u-cup style buffer ring offers an asymmetric sealing lip profile, chamfered sealing edges, and pressure relieving capabilities to prevent inner pressure entrapment when employed in a tandem sealing system. The RB rod buffer seal is designed to absorb impact pressure fluctuations under high-load conditions, thus increasing the life of the primary seal. RB buffers with "BU" suffix utilize polyacetal back-up rings where standard RBs do not.
