โอริง Buna กับ โอริง Nitrile – อันไหนดีที่สุดสำหรับการใช้งานของคุณ?

I once struggled with seal degradation in oil-heavy systems. The material you choose matters more than you think — especially between Buna O-rings และ โอริงไนไตรล์.

So, what’s the difference, and which one performs better in real applications?

Let’s compare these two materials in terms of oil resistance, temperature range, pressure stability, and best-fit applications.

Which material is more resistant to oils and fuels?

When it comes to petroleum-based systems, choosing the wrong material can lead to premature failure.

Buna O-rings outperform standard nitrile rubber in harsh oil and chemical environments.

Which one handles temperature and pressure better?

If your seals are exposed to heat, cold, or high PSI — choose wisely.

💡 For better temperature rangeไปด้วย Buna O-rings. For low-stress systems, nitrile is sufficient and more economical.

Which applications are better suited to each?

Use cases matter — here’s when I personally choose one over the other:

Buna O-Rings Are Best For:

• Fuel systems in vehicles and boats
• Hydraulic cylinders in industrial equipment
• Aerospace fluid systems
• Marine seals under harsh conditions

Nitrile O-Rings Are Best For:

• Air compressors and pneumatic fittings
• General plumbing or water handling
• Low-pressure HVAC units
• Cost-sensitive sealing tasks
