It supplies the load required for sealing at low pressures . The "U" shaped jacket allows fluid pressure to energize the sealing lips, so total sealing pressure rises with increasing operating pressure



Advantages

  • Suitable for reciprocating and rotary applications

  • Low coefficient of friction

  • Stick-slip free operating

  • High abrasion resistance

  • Dimensionally stable

  • Resistant to most fluids, chemicals and gases

  • Withstands rapid changes in temperature

  • No vulcanizing between seal and hardware

  • Excellent resistance to aging

  • Available in HiClean version
