Symmetrical Seals - 8400 Series - HRU

HRU and 8400 Series u-cups are symmetrical lip seals for use in either rod or piston sealing applications. The thin, flexible lip design reacts to low pressure and provides an extremely smooth, steady movement with less break away force required because of the inherent low friction. The HRU - 8400 style utilizes a beveled lip, ideal for wiping fluid film. Style HRU - 8400 u-seals are precision molded from 80 Durometer Buna-N rubber or FKM. While the HRU - 8400 U-cups are primarily designed for pneumatic applications, they can also be used in low to medium pressure hydraulic applications. The pressure range of the u-cups may be extended by incorporating an back-up ring.

*Fluorocarbon - FKM products end with a "V" all others are Buna-N 80 Durometer.
