Choosing between Silicone and NBR O-rings isn’t just a technical decision—it affects system life, cost, and compliance. So, which one should you choose?
Silicone O-rings are ideal for high heat and sterile environments, while NBR O-rings dominate oil-resistant industrial applications.
Let’s compare the differences and use cases to guide your selection.
What’s the difference between Silicone and NBR O-rings?
Silicone resists heat and UV, while NBR excels with oils and fuels. Your environment determines the right fit.
| Fitur | Cincin O silikon | Cincin O NBR |
|---|---|---|
| Kisaran Suhu | -50°C hingga 250°C | -40°C hingga 120°C |
| Terbaik Untuk | Heat, food, medical | Oil, fuel, hydraulics |
| Ketahanan Kimia | UV, ozone, dry heat | Oil, fuel, water |
| Biaya | Lebih tinggi | Lebih terjangkau |

Which O-ring material performs better in heat or oil?
- Menggunakan Cincin O Silikon for high-temperature, sterile, or outdoor conditions.
- Menggunakan Cincin O NBR in fuel, hydraulic, or lubricated environments.
| Milik | Silikon | Bahasa Inggris |
|---|---|---|
| Tahan Panas | ✅ Excellent (up to 250°C) | ❌ Moderate (up to 120°C) |
| Tahan Minyak | ❌ Miskin | ✅ Luar biasa |
| Tahan Cuaca | ✅ Luar biasa | ❌ Miskin |
How do industries apply Silicone and NBR O-rings?
Cincin O Silikon:
- Alat kesehatan
- Food & beverage systems
- Aerospace assemblies
Cincin O NBR:
- Fuel injection systems
- silinder hidrolik
- Automotive gaskets
Compare NBR to FKM O-Rings for more oil-based solutions.
What factors should you consider before choosing?
Use this simple checklist:
-
Suhu:
- Over 120°C → Silicone
- Under 120°C → Proceed to step 2
-
Media Exposure:
- Oil/fuel → NBR
- UV, dry heat, ozone → Silicone
-
Cost Sensitivity:
- Budget-critical → NBR
- Long-term performance → Silicone
