QUICK LINKS
SRVD - Double-acting rod composite seals
The SRVD rod seal is a combination of a filled PTFE ring (usually 40% bronze) and an energizing O-ring that ensures a good sealing effect even at low pressure. When system pressures are higher, the O-ring is pushed by the fluid against the sealing face with greater force. It is particularly suitable for applications such as injection moulding machines, machine tools, presses or valves for hydraulic or pneumatic circuits.
- Standard material: PTBR40 (PTFE + 40% bronze) + O-Ring NBR70
- Working temperature: -20 to +100/120 ºC
- Speed: <15m/s
- Pressure: <80mpa
