EXTERNAL SEALING
Description
GPR is a single-acting seal composed of a seal in filled PTFE and an energizing O-Ring.
Thanks to its excellent properties, it is particularly recommended as a single-acting piston seal requiring precise positioning and freedom of movement.
  • Simple installation, without seal deformation;
  • No stick-slip;
  • High wear and extrusion resistance;
  • Long service life;
  • Good static and dynamic sealing results.
