QUICK LINKS
SRVS - Simple-Acting Rod Composite Seal
The SRVS rod 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 piston rods of hydraulic systems such as cylinders, machine tools, injection molding machines or hammers. In combination with a scraper, SRVS rod seal ensures a perfect sealing.
- Standard material: PTBR40 (PTFE + 40% Bronze) + O-Ring NBR70
- Working temperature: -20 to +100/120 ºC
- Speed: <15m/s
- Pressure: <60mpa
