Product Description

 heat and chemical-resistant O-rings for gasoline, oil, and aggressive fluids, FPM/FKM (Fluorocarbon Rubber) and FFKM (Perfluoroelastomer) are the top choices for demanding industrial applications. Below is a detailed breakdown of their properties, manufacturing standards, and selection criteria.

1. Material Comparison for Gasoline & Chemical Resistance

Material	Temp. Range	Chemical/Gasoline Resistance	Key Advantages	Limitations
FKM (FPM/Viton®)	-20°C to +200°C (short-term +250°C)	Excellent resistance to fuels, oils, acids, and solvents	Cost-effective, widely available	Poor low-temp flexibility
FFKM (Kalrez®/Chemraz®)	-25°C to +325°C	Near-universal chemical resistance, including aggressive acids/bases	Extreme durability, low outgassing	Very high cost
NBR (Nitrile)	-30°C to +120°C	Good for gasoline/mineral oils	Budget-friendly	Fails in ozone/strong chemicals
HNBR	-40°C to +150°C	Better heat/ozone resistance than NBR	Improved lifespan	Not for polar solvents

2. Key Features of FKM/FFKM O-Rings

 Superior Fuel Resistance - Withstands gasoline, diesel, biofuels, and synthetic lubricants.
 High-Temp Stability - Performs in engine bays, chemical processing, and oil refineries.
 Low Compression Set - Maintains seal integrity under prolonged stress.
 Certifications - Compliant with FDA, NSF, UL, and NORSOK for critical applications.

  3. Manufacturing Standards for High-Performance Seals

• Precision Molding: Injection/compression molding for tight tolerances (ISO 3601 Class A).

• Post-Curing: Reduces extractables for cleanroom/medical use.

• QC Testing:

  • Fuel Immersion Testing (ASTM D471)

  • Compression Set (ASTM D395)

  • TR-10 Low-Temp Flexibility Test

  4. Top Applications

• Automotive: Fuel injectors, turbocharger seals, valve stems.

• Oil & Gas: Downhole tools, pipeline gaskets, refinery equipment.

• Aerospace: Jet engine seals, hydraulic systems.

• Chemical Processing: Pump seals, reactor gaskets.

  5. How to Select the Right O-Ring?

Consider these factors:
 Fluid Exposure (e.g., ethanol-blended fuels, sulfuric acid)
 Pressure/Vacuum Conditions
 Static vs. Dynamic Sealing
 Regulatory Needs (e.g., FDA for fuel contact)

  6. Custom O-Ring Options

• Materials: FKM (70A-90A hardness), FFKM (for extreme environments).

• Coatings: PTFE coating for reduced friction.

• Sizes: AS568, metric, or custom dimensions.
