DPE consists of a profile ring made of PTFE with a sealing edge and wiper edge, and two O-rings as sealing and preloading parts. DPR for improved overall sealing. DSH Seals’ DPR is primarily used in conjunction with our rod seal. Set a pressure relief hole between the seal and the wiper.

Characteristics:

  • Excellent operating practices and positioning.
  • Low friction, no stick slip.
  • Short stroke and high frequency material variants.
  • High reliability, can accept the full operating pressure for short periods.
