Metric Wiper

Description:

The DW wiper is a low friction wiper consisting of one sealing element with a sealing edge and a wiping edge, with two O-Rings for the energizing components. The O-Rings maintain pressure on the sliding surface and offers compensation for deflection during strokes.

We recommend a bore hold for relieving pressure. No pressure release is needed for these seals with a good back-pumping action.

Features:
  • Prevents Stick-slip
  • Available in high temperature thermoplastic materials and when combined with a FFKM O-ring, the SW Wiper can be used in applications up to 260°C
  • High resistance to chemical attack
  • Low Friction
  • Extended wear resistance
  • Good scraping ability
  • Good ability to handle pressure spikes
Applications:
  • Servo Valves
  • Industrial Hydraulics
  • Molding Machines
  • Rolling mills
  • Fork Lifts
  • Downhole Tools
