Technical Specifications and Applications of FPM O-Ring 9x4 - Chemical & Temperature Resistance
The FPM O-Ring 9x4 (Viton / FKM) is a premium fluoroelastomer (FPM / FKM) sealing ring with 9 mm inner diameter (ID) and 4 mm cross-sectional thickness (CS). It is engineered for demanding applications requiring superior chemical resistance, thermal stability, and low permeation.
Key Features & Benefits:
-
Excellent resistance to oils, fuels, aromatics, and many aggressive media
-
Wide working temperature range (typical: -20 °C to +200 °C, sometimes up to ~205 °C depending on the specific FPM formulation)
-
Low compression set, good elasticity, and durability under cyclic loads
-
Minimal swelling in hydrocarbons
-
Suitable for static and - with care - dynamic sealing with compatible lubrication
-
Available in various hardness grades (e.g. 75, 80 Shore A) to match application stress
Technical Specifications:
| Parameter | Value / Range | Notes |
|---|---|---|
| Inner Diameter (ID) | 9 mm | Standard metric measurement |
| Cross Section (CS) | 4 mm | Typical cord thickness |
| Material | FPM / FKM / Viton | Fluoroelastomer sealing compound |
| Typical Hardness | 70-80 Shore A (or other on request) | Hardness influences performance under pressure |
| Operating Temperature | -20 °C to +200 °C (up to ~205 °C) | Depends on grade and duty cycle |
| Limitations | Not ideal for strong ketones, steam, or strong acids under extreme conditions | Typical constraint of fluoroelastomers |
Typical Applications:
FPM O-Ring 9x4 is widely used in industrial, automotive, hydraulic, pneumatic, and chemical equipment for sealing in fuel systems, pumps, valves, and various process instruments.
Usage Notes & Selection Guidance:
-
Always confirm the temperature, pressure, and chemical environment.
-
Opt for a hardness grade (Shore A) suitable to balance flexibility and mechanical strength.
-
In dynamic applications, use compatible lubrication and ensure proper groove design.
-
Verify tolerances and standard dimensions (e.g. DIN / ISO) for accurate fit.

📚 FAQ (Frequently Asked Questions)
Q: What does “FPM” mean in FPM O-Ring 9x4?
A: FPM (also called FKM) is the standard designation for a fluoroelastomer material (e.g. Viton®) known for excellent heat, chemical, and oil resistance.
Q: What temperature range can the FPM O-Ring 9x4 handle?
A: Typically from -20 °C up to +200 °C (in many cases short-term up to ~205 °C), depending on the specific FPM compound and duty cycle.
Q: Can FPM O-Ring 9x4 be used in fuel systems?
A: Yes — due to its good resistance to fuels, oils, and hydrocarbons, it is frequently used in automotive and industrial fuel sealing applications.
Q: Which hardness (Shore A) should I choose?
A: Lower hardness (70) gives more flexibility under lower pressures; higher hardness (80) provides better mechanical strength in higher pressure setups.
Q: How to install FPM O-Ring 9x4 without damage?
A: Use a thin film of compatible lubricant, avoid sharp edges, gently stretch (if needed) without exceeding elastic limits, and ensure proper groove geometry.
