Polypac High-Speed Cylinder Seal

Overview

The Polypac High-Speed Cylinder Seal is designed for hydraulic cylinders that operate at high piston speeds and under demanding conditions. Combining low friction, excellent wear resistance, and consistent sealing performance, this seal protects equipment, reduces downtime, and extends service life.

Why Choose Polypac High-Speed Cylinder Seal

Polypac is a scientific and technical manufacturer specializing in seals and sealing materials. Founded in 2008, our factory covers more than 10,000 m² with 8,000 m² of production space and advanced testing equipment. We produce a wide range of materials, including filled PTFE variants and elastomers like NBR, FKM, silicone, EPDM and FFKM. Our long-term partnerships with universities and research institutions ensure continuous improvement and reliable products.

Key Benefits

• Low friction for smooth operation at high speeds
• High wear and extrusion resistance
• Stable sealing across temperature and pressure ranges
• Reduced maintenance and longer service intervals
• Custom sizes and materials for special working conditions

Materials & Construction

Our High-Speed Cylinder Seals use advanced materials such as bronze-filled PTFE, carbon-filled PTFE, and MoS₂-filled PTFE for sliding parts, paired with durable elastomer energizers (NBR, FKM, EPDM, etc.). This combination ensures a tight seal with minimal wear and consistent performance at high piston speeds.

Applications

Ideal for mobile and industrial hydraulics where rapid piston movement is common: construction machinery, agricultural equipment, presses, injection molding machines, and other high-speed hydraulic systems.

Customization & Quality Assurance

Polypac offers tailored sealing solutions for special environments—high temperature, aggressive fluids, or extreme pressure. Every seal undergoes strict testing, including dimensional checks, material verification, and performance testing to ensure reliability in the field.

Trust and Support

Choosing Polypac means choosing a partner with deep industry experience and a commitment to quality. Our technical team supports product selection, testing, and custom design to meet your specific needs.
