Style DYR-BHT buffer seals are molded in Freudenberg� AU 30000 urethane. 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. This rod buffer seal is designed to absorb impact pressure
fluctuations under high-load conditions thus increasing the life of the primary seal. This high tear-resistant urethane
demonstrates stability throughout a wide range of temperatures. In addition, this material is well suited to mineral and
biodegradable hydraulic fluids as well as being resistant to hydrolysis.
