Full Product Description

AVAILABILITY: A sampling of Parker’s part numbers are shown in the configurator above for select materials and sizes. If the material and dimensions required are not shown, assistance with part number configuration may be found in the literature documents in the Product Support tab. To check current tooling, review the Part Number Look-up document found in Product Support tab. Contact Parker for requirements outside standards shown.

Parker’s BD Profile is a single-acting, non-symmetrical profile rod seal for hydraulics. The o-ring energizer functions as a spring to maintain sealing contact under vacuum, low pressure, and cold temperature conditions. The knife trimmed, beveled lip does an excellent job wiping fluid film. Its rectangular shaped cross section ensures stability in the gland. A stabilizing 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
• Excellent 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 Profile rod buffer seal for more critical sealing applications.

Enhanced extrusion resistance: For enhanced extrusion protection, the BD Profile may be designed with a positively actuated back-up ring located in the heel (see BD Profile with Back-up Ring).

Standard Materials (Shell or Seal Body):
• P4300A90 Resilon® polyurethane; Temp -65 / +275F; Pressure* 5000 psi; Surface speed <1.6 ft/s (100 fpm)
