The YCC PGY Series Piston Seal Ring is a precision-engineered sealing solution specifically designed for pneumatic cylinder applications. Utilizing advanced polyurethane compound and optimized sealing geometry, this seal delivers zero-leakage performance, minimal friction, and extended service life in demanding pneumatic systems.

• Zero Air Leakage — Advanced lip design ensures perfect sealing, minimizing energy loss to the maximum extent.
• Long Service Life — Excellent wear resistance performance.
• Easy Installation — Symmetrical design allows for convenient installation without considering direction.
• Universal Compatibility — Suitable for all SC standard cylinders.

This type of YCC pneumatic piston seal can be easily mounted onto the piston and installed into the groove. To avoid damaging the seal lip during installation, the sharp edges on both the piston and the cylinder should be removed. In the absence of lubrication, it is crucial to have a complete lubricant film inside the cylinder barrel, which should be ensured prior to assembly to guarantee the service life of the seal.

• Optimized Lip Profile: Computer-optimized design ensures consistent sealing performance across all pressure ranges.
• Material Science: Utilization of NBR material provides excellent wear resistance while maintaining elasticity.
• Precision Manufacturing: CNC machining guarantees dimensional accuracy and batch consistency.

• 100% pressure testing before shipment
• Dimensional verification with optical measuring equipment
• Performance testing in simulated operating conditions

• Free application analysis
• Custom design services
• Installation guidance and documentation
• On-site technical support available
