Product Information

Overview

Polypac Abrasion Resistant Seal is designed to deliver reliable, long-lasting protection in harsh environments. Built by Polypac — a technical seal manufacturer founded in 2008 — these seals combine proven materials and modern production to resist wear, reduce maintenance, and keep hydraulic and oil systems running smoothly.

Key Benefits

High wear resistance for extended service life
Reduced downtime and lower maintenance costs
Stable performance under pressure, heat, and oil exposure
Available in a wide range of materials and sizes

Material Options

We offer abrasion-resistant seals in a variety of proven materials, including filled PTFE (bronze, carbon, graphite, MoS₂, glass) and elastomers such as NBR, FKM, silicone, EPDM, and FFKM. This lets you choose the best balance of wear resistance, chemical compatibility, and temperature range for your application.

Customization & Quality

Polypac’s custom rubber ring and O-ring factory covers over 10,000 m² with 8,000 m² of production space and advanced testing equipment. We work closely with universities and research institutions to develop materials and solutions for special working conditions. Custom sizes, profiles, and compound formulations are available to match your equipment precisely.

Applications

These abrasion resistant seals are ideal for hydraulic cylinders, oil systems, mobile equipment, industrial presses, and any application where sliding contact and particulates cause wear. They perform well in both low-speed/high-pressure and dynamic sealing conditions.

Why Choose Polypac

Choosing Polypac means partnering with a leading Chinese seal maker committed to quality, testing, and customer service. From filled PTFE origins to modern elastomer O-rings, we provide practical, durable sealing solutions that protect your equipment and reduce lifecycle costs.

FAQ

How can I prevent seal damage during installation?

Use Tools: Always use dedicated installation tools (e.g., picks, cones, guides). Lubricate: Always lubricate the seal and the contact surface. Protect Sharp Edges: Cover sharp threads and edges with tape or use an installation sleeve. Check the Groove: Ensure the installation groove is clean, deburred, and undamaged.

How do I choose the right material for my sealing application?

Material selection depends on four key factors: Media: What fluid or gas will the seal contact? (e.g., petroleum oil, water, chemicals, steam) Temperature: What is the minimum and maximum operating temperature? Pressure: What is the system's operating pressure? Are there pressure spikes? Application: Is it a static, dynamic, or rotary seal? Example: NBR (Buna-N) is excellent for standard hydraulic oil, while FKM (Viton®) is needed for high temperatures or aggressive chemicals.

When should I use a spring-energized seal instead of a standard elastomeric seal?

Consider a spring-energized seal (e.g., GSF, SPN types) for demanding applications involving: Extreme Temperatures (below -30°C or above +200°C) Aggressive Chemicals that elastomers can't handle Very Low Leakage or "Zero Leakage" requirements Poor Lubricity or dry running conditions The internal spring maintains constant sealing force, compensating for wear and system variables.

What is the purpose of the metal spring in a rotary shaft seal?

The garter spring in a shaft seal (e.g., FSKR, SPGO types) provides a constant radial force on the sealing lip. This ensures consistent contact with the rotating shaft, compensating for minor wear, eccentricity, and vibration to prevent lubricant leakage.
