The CS03-F is a premium asymmetric single-acting rod seal featuring a PTFE sealing element and an O-ring energizer. The O-ring provides the necessary preload, ensuring an excellent sealing effect across a wide temperature and pressure range up to 200 bar. Designed for low friction and zero stick-slip, it excels in dry-running conditions and media with poor lubrication. Whether for short or long-stroke applications in chemical fittings or hydraulic cylinders, the CS03-F offers superior static and dynamic sealing with minimal break-away force and no reverse leakage.
• O-Ring Energized Design: Ensures constant preload and superior sealing in all pressure ranges.
• Ultra-Low Friction: PTFE material prevents stick-slip and allows for dry running.
• Chemical Excellence: Highly resistant to aggressive media when paired with FKM or specialized PTFE.
• No Reverse Leakage: Maintained sealing integrity even during direction changes.
• Versatile Motion: Suitable for reciprocating, swiveling rods, and valve lifters.
• Wide Temp Range: Reliable performance in extreme thermal environments.
