Fluorocarbon O-Ring Kits — Polypac FKM Seals & Custom Kits
Fluorocarbon O-Ring Kits by Polypac
Product Overview
Polypac Fluorocarbon O-Ring Kits provide a comprehensive selection of FKM (fluoroelastomer) O-rings engineered for demanding environments. Each kit combines common AS568 and metric sizes to supply maintenance teams, OEMs, and field service engineers with reliable sealing parts. These Fluorocarbon O-Ring Kits are designed for immediate use and long-term storage without loss of performance.
Material & Performance
Fluorocarbon (FKM) offers exceptional resistance to high temperatures, hydrocarbons, oils, fuels and many aggressive chemicals. Our Fluorocarbon O-Ring Kits feature compounds optimized for thermal stability (-20°C to +200°C typical), low compression set, and excellent dimensional stability—ensuring leak-free performance in hydraulic systems, engines, and chemical processing equipment.
Manufacturing & Quality Assurance
Produced in Polypac’s advanced factory (over 10,000 m², 8,000 m² production space), our Fluorocarbon O-Ring Kits are manufactured on industry-leading presses and verified with rigorous testing equipment. We collaborate with top universities and research institutes to refine formulations and meet international standards. Every batch undergoes hardness, tensile, compression set and chemical compatibility testing to guarantee consistency.
Customization & Kit Options
Polypac offers standard pre-packed kits and fully customized kits tailored to your parts list, sizes and packaging preferences. Options include AS568 sizes, metric sizes, color coding, bulk or compartmented boxes, and specialized FKM grades for extreme media. Custom mixing and mold tooling allow rapid development of special compounds for unique service conditions.
Applications & Industries
Our Fluorocarbon O-Ring Kits serve hydraulic systems, automotive fuel systems, aerospace components, chemical processing, oil & gas equipment and industrial machinery. They are recommended where oil, solvent and high-temperature resistance are critical.

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 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.
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.
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.
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.
