Wear Resistant Seals - Polypac Premium Sealing Solutions
Wear Resistant Seals — Durable Solutions by Polypac
Polypac specializes in Wear Resistant Seals designed to extend service life and reduce maintenance in demanding hydraulic and oil applications. Founded in 2008, Polypac combines cutting-edge material science with large-scale precision manufacturing across a 10,000+ m² facility. Our product range includes filled PTFE variants (bronze, carbon, graphite, MoS₂, glass) and elastomer O-rings in NBR, FKM, silicone, EPDM and FFKM — all engineered for superior abrasion resistance, low friction and consistent sealing under dynamic and static conditions.
Applications
Wear Resistant Seals from Polypac are ideal for heavy-duty hydraulic cylinders, rotary shafts, pumps, compressors and mobile equipment exposed to abrasive media, particle contamination, high loads or frequent cycling. Typical industries include construction, mining, oil & gas, marine and industrial hydraulics where uptime and predictable performance are critical.
Materials & Technology
We combine advanced filled PTFE compounds with tailored elastomers to balance wear resistance, chemical compatibility and thermal stability. Filled PTFE options provide exceptional low-friction and abrasion tolerance; FKM and FFKM offer high-temperature and chemical resistance; NBR and EPDM provide cost-effective sealing in oil and water systems. Polypac’s material development focuses on minimizing extrusion, preventing edge wear and optimizing friction for energy efficiency.
Customization & Testing
As a scientific and technical seal manufacturer, Polypac offers bespoke design services for special working conditions — custom geometries, compound formulations and surface treatments. Our production and testing lines are among the most advanced in the industry, enabling rigorous wear, pressure, temperature and lifecycle testing. Long-term partnerships with universities and research institutes ensure continuous improvement and validated performance data.

What does "AS568" mean?
AS568 is the Aerospace Standard that defines the dimensions for over 360 standard O-ring sizes. It is the most widely accepted sizing system in North America and globally. An AS568 number (e.g., AS568-214) specifies a precise inside diameter and cross-section.
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.
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.
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.
