Double acting piston seals (DAP)

DAP is a double-acting seal for piston application. The seal consists of a high performance elastomer sealing element, and two split hard polymer wear rings. The elastomer sealing element is tightly fitted into a housing so as to ensure a good seal even at low pressures. The wear rings act as bearings to guide the piston within the cylinder bore. We make standard and non-standard sizes for the DAP.

Features:

  • Operating pressure: up to 500 bar (can be extended with modify materials and profile)
  • Operating temperature: -20 degree celcius up to 110 degree celcius (depending on materials)
  • Reciprocating speed: up to 0.5 m/s
