B3 Profile, U-cup Rod Seal

B3 Profile, U-cup Rod Seal


The B3 profile is a non-symmetrical design for use in hydraulic rod sealing applications. The diameter of the B3 profile is designed to ensure a tight static side seal when installed. The knife trimmed, beveled lip does an excellent job wiping fluid film. The B3 profile is available in Parker proprietary compounds offering extrusion resistance, long wear, and low compression set. The B3 profile is designed for use as a stand alone rod seal and can be used with Parker’s BR or OD profile buffer seals for more critical sealing applications. The B3 profile does not utilize a secondary sealing lip and can be used with a double lip wiper seal, such as the AY profile, to provide a multiple lip, rod sealing system without trapping pressure.
