PERFORMANCE ADVANTAGES
The BR Profile is a compact rod seal designed to act as a buffer seal for the primary rod seal. As a buffer seal, the BR profile provides the majority of the rod sealing performance while allowing fluid to bypass and energize the primary rod seal. Fluid located between the BR profile and the rod seal will relieve back into the cylinder by flowing past the BR profile's flexible static side lip and slotted pedestals. This relieving, or check valve function, allows the BR profile and primary rod seal to work as a sealing system without danger of developing a pressure trap. As a sealing system, the BR profile and primary rod seal provide optimal performance in the most difficult applications. The design incorporates a positively actuated back-up ring in the heel of the dynamic surface to prevent gap extrusion and to extend high pressure sealing capability.

Available in Parker's proprietary Resilon® high performance polyurethane, the BR Profile provides
• Long life
• Extrusion resistance
• Low compression set
• Robust shock load resistance
• Enhanced sealing performance in non-pressured conditions.
