Best Practices for Choosing Oil-Resistant and High-Temperature Seals (120°C)

Although NBR seals are known for their excellent oil resistance, including fuel oils, petroleum oils, vegetable oils, and animal fats, did you know that their performance significantly declines at high temperatures? When NBR seals are used at 120°C, which is their maximum temperature limit, their oil resistance drastically reduces, leading to deterioration within just 5-10 days.

Issues with Using NBR Seals at High Temperatures
- Frequent replacements, leading to increased costs
- Production disruptions, requiring frequent shutdowns for seal replacements
- Increased industrial waste, negatively impacting the environment
- Incorrect material selection, resulting in inefficient performance

How to Extend the Service Life of NBR Seals
To maximize the durability of NBR seals, it is recommended to use them at temperatures not exceeding 70°C. This helps maintain their effectiveness and slows down degradation. Additionally, using high-quality NBR sealsspecifically designed for industrial applications ensures better performance and longevity.

The Best Alternative for Oil-Resistant and High-Temperature Seals (120°C)
For applications requiring both oil resistance and high-temperature endurance, QO-grade silicone rubber seals are an excellent alternative. Although their oil resistance is not as strong as NBR, they last significantly longer than NBR seals in high-temperature environments.

Key Features of QO-Grade Silicone Rubber Seals
- Withstands temperatures up to 220°C, ideal for continuous high-temperature applications
- High flexibility, available in various profiles and complex cross-sections
- Longer lifespan, reducing long-term costs compared to NBR
- Environmentally friendly, minimizes waste and reduces carbon footprint
- More cost-effective than Viton (FKM) seals, while still providing excellent oil and heat resistance
