3 x 3.5 x .375" Parker® High-Temp 4300 Urethane Twin Lip Rod U-Cup

The BT profile is a non-symmetrical design for hydraulic rod sealing applications. Using Finite Element Analysis, the BT profile was designed to provide improved sealing performance and stability in the gland. BT profile has a more robust primary sealing lip than the BS profile and the stabilizing lip is located at the base of the heel. The standard compound for the BT profile is Parkers® proprietary Resilon® polyurethane 4300 compound. Provides long life, extrusion resistance, low compression set, shock load resistance and increased sealing performance at zero pressure. Designed for use as a stand alone rod seal or for use with the BR or OD profile buffer seals for more critical sealing applications. Request Quote
