Product Information

Overview of Polypac PTFE O-Rings

Polypac PTFE O-Rings are engineered for demanding environments where chemical resistance, low friction, and long service life matter. Built on our years of experience in PTFE seal production, these O-rings offer reliable sealing for hydraulic systems, chemical equipment, pumps, and valves.

Key Benefits

Chemical and Temperature Resistance

PTFE material resists most chemicals and solvents and performs well over a wide temperature range. This makes Polypac PTFE O-Rings a trusted choice for corrosive media and high-temperature applications.

Low Friction and Wear Resistance

The low friction surface of PTFE reduces wear and stick-slip. That improves efficiency and extends the life of moving parts in rotary and reciprocating seals.

Stable and Predictable Performance

PTFE maintains its shape and sealing performance under pressure and thermal cycling, providing dependable operation where other elastomers may fail.

Applications

Common uses include hydraulic cylinders, pumps, valves, chemical processing, semiconductor equipment, and any system where aggressive media or high temperatures are present. Polypac PTFE O-Rings are suitable for both static and low-speed dynamic sealing.

Customization and Quality Assurance

Custom Sizes and Materials

Polypac offers custom O-rings in a variety of PTFE grades including filled and modified PTFE for enhanced wear or conductivity. We also supply multiple elastomer options like NBR, FKM, silicone, EPDM, and FFKM for hybrid sealing solutions.

Advanced Manufacturing and Testing

Our factory spans over 10,000 m2 with 8,000 m2 of production space and advanced equipment for precision manufacturing. We partner with universities and research institutions to ensure materials and processes meet strict standards. Every O-ring undergoes rigorous inspection to ensure dimensional accuracy and material integrity.

Why Choose Polypac?

Founded in 2008, Polypac combines specialized PTFE experience with modern production and testing capabilities. We provide trusted, customizable sealing solutions and responsive technical support to ensure you get the right O-ring for your application.

Question you may concern

Can I reuse a seal?

We strongly recommend never reusing seals. Once compressed and used, a seal takes a "set" and its elastic properties are degraded. Reusing it almost always results in a leak. Always install a new seal during any maintenance or repair.

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.

What is the difference between a static seal and a dynamic seal?

A Static Seal is used between two surfaces that do not move relative to each other (e.g., pipe flanges, end caps). O-rings and gaskets are common static seals. A Dynamic Seal is used between surfaces that do move (e.g., piston and cylinder, rotating shaft). Rod seals, piston seals, and rotary shaft seals are designed for this purpose.
