Parker's BS profile is non-symmetrical profile designed for use in rod sealing applications. A knife trimmed back beveled sealing lip does an excellent job wiping fluid from the rod. In addition, a secondary sealing lip is located just above the base of the seal to provide enhanced sealing performance and ensure a tight, stable fit in the gland. Available in Parker's proprietary urethanes, the BS profile provides long life, resistance to extrusion, low compression set, shock load resistance and increased sealing performance at zero pressure. The BS profile is designed to be used as a stand alone rod seal or for use with the BR or OD Buffer Seals for more critical sealing applications.
