Parker’s BT Profile is a single-acting, non-symmetrical rod seal for hydraulics.   The U-cup shaped seal features a robust knife trimmed, beveled lip which 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 Resilon® polyurethanes, the BT Profile provides
• Long life
• Extrusion resistance
• Low compression set
• Shock load resistance, and
• Excellent sealing performance at zero pressure

The BT 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.

Standard Materials:
• P4300A90 Resilon® polyurethane; Temp -65 / +275F; Pressure* 5000 psi; Surface speed
