Silicone O-Rings vs. NBR O-Rings – Which One is Best for Your Needs?| Hengoseal

• Silicone O-Rings excel in high-temperature applications，while NBR O-Rings provide superior oil and fuel resistance。
• Silicone O-Rings withstand temperatures from -50°C to 250°C，whereas NBR O-Rings function between -40°C and 120°C。
• Silicone O-Rings are widely used in medical, aerospace, and food processing，while NBR O-Rings are essential for automotive, hydraulic, and fuel systems。

What Are the Key Differences Between Silicone O-Rings and NBR O-Rings?

Choosing the right O-Ring depends on temperature resistance, chemical exposure, and industry application。Silicone O-Rings are heat-resistant, while NBR O-Rings excel in fuel and oil environments。

How Do Silicone O-Rings and NBR O-Rings Work?

• Silicone O-Rings: Made from silicone rubber, they resist ozone, UV, and extreme temperatures but are not resistant to petroleum-based fluids or water。
• NBR O-Rings: Made from nitrile butadiene rubber, they provide excellent oil, fuel, and hydraulic fluid resistance, but degrade when exposed to ozone and UV。

How Do Silicone O-Rings Compare to NBR O-Rings?

Silicone O-Rings offer superior heat resistance, while NBR O-Rings provide excellent oil and fuel compatibility。Selecting the right O-Ring ensures durability and optimal performance。
