SRPS

SRPS piston seal is the combination of a PTFE + filler ring (generally 40% bronze) and an energizing O-Ring that has an excellent sealing effect in dynamic and static applications such as double-acting cylinders, machine tools or construction machinery.

  • Standard material: PTBR40 (PTFE + 40%bronze) + O-Ring NBR70
  • Working temperature: -20 to +100/120 ºC
  • Speed: <15m/s
  • Pressure: <80mpa
