BD Profile, Premium O-Ring Energized Lip Seal

BD Profile, Premium O-Ring Energized Lip Seal


The BD profile is a non-symmetrical profile rod seal. Its rectangular shaped cross section ensures stability in the gland. The O-ring energizer functions as a spring to maintain sealing contact under low pressure or vacuum applications. The knife trimmed, beveled lip does 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, extrusion resistance, 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. Also available with a positively-activated back-up.

Options: A back-up ring located in the heel of the BD profile can be provided for enhanced extrusion protection. See part number nomenclature for designating this option. Contact your local Zatkoff Seals & Packings representative for price and availability.
