Product Overview
The FKM O-Ring (10.6 * 2.65 mm) is a high-performance sealing component manufactured from premium Fluoroelastomer (FKM/Viton® equivalent material), specifically designed for demanding automotive electronics and consumer electronics applications. With excellent resistance to high temperatures, fuels, oils, chemicals, ozone, and environmental aging, this O-ring provides reliable sealing performance in harsh operating conditions.
The 10.6 mm inner diameter and 2.65 mm cross-section design make it ideal for compact electronic assemblies, automotive sensors, connectors, battery systems, charging devices, smart appliances, and waterproof electronic housings. Compared with conventional NBR or EPDM seals, FKM O-rings offer superior durability, longer service life, and better resistance to aggressive fluids and elevated temperatures.
Whether used in electric vehicles, automotive control modules, smart home devices, or portable consumer electronics, this FKM O-ring ensures consistent sealing performance, preventing leakage, dust ingress, moisture penetration, and contamination.
Why Do Electronic Devices Need High-Performance FKM O-Rings?
Modern automotive and consumer electronic products are becoming increasingly compact while operating under more challenging environmental conditions.
Common sealing challenges include:
- High operating temperatures
- Exposure to oils and lubricants
- Humidity and water ingress
- Dust contamination
- Thermal expansion and contraction
- UV and ozone exposure
- Chemical cleaning agents
- Long-term aging requirements
Traditional rubber seals may harden, crack, swell, or lose elasticity over time, leading to:
❌ Water leakage
❌ Dust penetration
❌ Sensor malfunction
❌ Connector corrosion
❌ Electronic component failure
❌ Increased maintenance costs
For manufacturers seeking long-term reliability, FKM O-rings have become the preferred sealing solution.

How It Works
An O-ring functions as a compression seal.
When installed into a designed groove and compressed between two mating surfaces, the FKM elastomer deforms elastically to fill microscopic gaps.
Sealing Process
- The O-ring is placed in a precision groove.
- Two mating components are assembled together.
- Compression creates sealing force.
- The elastomer fills surface irregularities.
- Internal pressure further enhances sealing effectiveness.
- The seal prevents leakage of liquids, gases, dust, and contaminants.
The high elasticity and chemical stability of FKM ensure long-term sealing performance even under extreme temperatures and harsh chemical exposure.
How To Choose the Right FKM O-Ring
Selecting the correct O-ring is critical for sealing performance.
1. Confirm Dimensions
Check:
- Inner Diameter (ID)
- Outer Diameter (OD)
- Cross Section (CS)
For this model:
2. Evaluate Operating Temperature
Choose FKM when:

- Exposure to heat cycling is frequent
- Long-term thermal stability is required
3. Consider Chemical Exposure
FKM is recommended for contact with:
- Automotive oils
- Fuels
- Hydraulic fluids
- Greases
- Cleaning chemicals
- Industrial solvents
4. Determine Sealing Environment
Consider:
- Static sealing
- Dynamic sealing
- Water resistance requirements
- Dust protection requirements
- Pressure levels
5. Compliance Requirements
For export projects, verify:
- RoHS
- REACH
- FDA (if required)
- Automotive industry specifications
