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
