Description:

The PPS piston seal is a two-piece seal set consisting of an O-Ring energizer and a symmetrical PTFE sealing element. When the pressure rises the O-Ring will deform and compresses the PTFE sealing element, increasing the sealing force, improving the seal-ability and life expectancy. This seal exhibits low friction and has high strength chamfer corners for cold flow resistance.

  • Prevents stick-slip
  • High resistance to chemical attack
  • Low friction
  • High speed
  • Very high pressure stability under load
Applications
  • Mobile hydraulics
  • Industrial hydraulics
  • Molding machines
  • Downhole tools
  • Used a buffer seal
  • Rolling mills
  • HGV loading cranes
  • Wind turbines
