Pneumatic Piston Seal Type KDN Pneumatic Material NBR FESTO Valve Seal

The Type KDN Pneumatic Piston Seal is a high-performance sealing component engineered with innovative low-friction materials and a unique lip design. Optimized to address challenges such as dry friction, high-speed motion, and high cycling frequency in pneumatic systems, it effectively reduces energy consumption, ensures smooth operation, and significantly extends the service life of cylinders.

• Ultra-Low Friction: Made from modified PTFE or specialized polyurethane materials, it minimizes breakaway friction, ensuring smooth cylinder movement even at low speeds without "stick-slip" phenomena.
• Zero-Leakage Performance: The precision-designed sealing lip delivers excellent sealing even at low air pressures, minimizing internal leakage and ensuring consistent output force.
• Extended Service Life: Exceptional wear resistance provides a lifespan several times longer than traditional seals, drastically reducing maintenance frequency and total cost of ownership (TCO).
• Broad Temperature Compatibility: Maintains stable performance within a temperature range of -20°C to +110°C, suitable for most industrial environments.
• Easy Installation: Symmetrical or asymmetrical design (depending on the specific model) with simple groove design for straightforward installation, reducing errors.

This seal is ideal for:

• Factory Automation: Robot drive cylinders, gripping units, linear drive modules.
• Packaging & Handling Equipment: Sorting machines, labeling machines, filling machine cylinders.
• Food & Beverage Industry: Equipment compliant with relevant regulations (specific material certifications available upon request).
• Semiconductor & Electronics Manufacturing: High-precision pneumatic equipment in cleanroom environments.
• Medical Devices: Respirators, analyzers, and other applications requiring quiet and smooth operation.
