PARKER BR ROD SEAL

    BR Rod Seal

    Descriptions

    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 by pass
    onto 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 the 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.
