The BD profile is a non-symmetrical profile hydraulic rod seal. Its rectangular shaped cross section ensures stability in the gland. An O-ring energizer functions as a spring to maintain sealing contact under low pressure or vacuum applications. Knife trimmed, beveled lips do an excellent job wiping fluid film. A secondary sealing lip is located below the primary sealing lip, 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 BD profile provides long life, resistance to extrusion, low compression set, shock load resistance and increased sealing performance at zero pressure. The BD profile is designed to be used as a stand alone rod seal or for use with the BR or OD profile buffer seals for more critical sealing applications.
