Piston Rings (Polymer & Composite Grades)
Our Piston Rings are precision-engineered from high-performance polymers such as PTFE, PEEK, and filled engineering plastics, ideal for dynamic sealing in linear and rotary motion systems. These rings provide excellent wear resistance, self-lubrication, and low friction—making them ideal for compressors, hydraulic cylinders, shock absorbers, and rotary actuators. Designed to withstand high temperatures, aggressive media, and continuous motion, our piston rings offer reliable sealing even in extreme operating conditions. We offer customized solutions for OEMs and replacement applications with tight dimensional tolerances and consistent quality.
High-Speed. Low-Friction. Wear-Resistant.
Key Features & Applications
