TECHNICAL DATA
| Seals | Profile | Material | Temperature | Speed | Pressure |

| SRPD |  | PTFE + 40% BRONZE + NBR70 | -20 to +120 ºC | 15 < m/s | 60 < Mpa |
SRPD - Double-Acting Piston Composite Seal
SRPD piston seal is the combination of a PTFE + Filler ring (generally 40% bronze) and an energizing O-Ring. It is a model particularly well adapted to applications with alternative and helicoidal movements 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: <60mpa
