Rod Seals

U-cup style buffer ring offers an asymmetric sealing lip profile, champhered sealing edges, and pressure relieving capabilities to prevent inner pressure entrapment when employed in a tandem sealing system. This rod buffer seal is designed to absorb impact pressure fluctuations under high-load conditions thus increasing the life of the primary seal. Items with BU" in Back Up column have polyacetal back-up. Standard KRI20-A's do not.
