Wear Resistant Seals — Reliable Protection from Polypac

Polypac Wear Resistant Seals are engineered to extend the life of hydraulic and oil systems in demanding environments. Using years of material research and advanced manufacturing, our seals combine low friction, excellent wear resistance, and consistent sealing performance. They are ideal for heavy-duty machinery, high-speed shafts, and aggressive working conditions.

Materials and Options

We offer a wide range of materials to match different operating needs: filled PTFE (bronze, carbon, graphite, MoS2, glass) for low friction and high wear resistance, plus elastomers such as NBR, FKM, silicone, EPDM, and FFKM for flexible sealing and chemical compatibility. Custom blends and bonded designs are available for special conditions.

Key Features

- Exceptional wear resistance that reduces maintenance and downtime.
- Low friction to improve efficiency and protect mating surfaces.
- Wide temperature and chemical compatibility for harsh environments.
- Precision manufacturing for consistent dimensions and reliable performance.
- Custom design and material selection to meet special application requirements.

Q&A

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.
Why did my O-ring fail prematurely?
Common causes of O-ring failure include: Chemical Incompatibility: Swelling, softening, or cracking due to fluid exposure. Improper Sizing: Using an incorrect size leads to over-compression or inadequate sealing force. Abrasion: Wear and tear from rough surface finishes or contaminated fluid. Extrusion: The seal is forced into the gap between metal parts under high pressure. Installation Damage: Nicks, cuts, or twists during assembly.
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.
How important is surface finish on the metal parts that contact the seal?
Extremely important. A rough surface will abrade and wear out the seal quickly, causing leaks. A finish that is too smooth can prevent a lubricating film from forming. A typical recommended surface finish for dynamic applications is 0.2 to 0.8 μm (8-32 μin) Ra.
