We’re excited to announce the launch of our latest range of NBR O-Rings & Seals, engineered for performance, reliability, and cost-effective sealing across a wide range of industrial and everyday applications. Whether you’re a procurement manager sourcing components in bulk or a DIY enthusiast looking for dependable sealing solutions, our new NBR O-Rings range delivers performance you can trust.

What are NBR O-Rings?

NBR (Nitrile Rubber), also known as Buna-N, is the most cost-effective and commonly available O-ring material on the market today. It is widely used across the hydraulic and pneumatic industries due to its excellent resistance to oils and fuels, combined with strong mechanical properties.

NBR is ideal for use as seals in:

• Pumps
• Drive belts
• Hydraulic systems
• Pneumatic equipment
• General engineering applications

It performs particularly well in applications where the O-ring is exposed to:

• Fats
• Greases
• Animal oils
• Vegetable oils
• Petroleum-based fluids

This versatility makes it one of the most practical and widely specified sealing materials worldwide.

How Do NBR O-Rings & Seals Work?

An O-ring is a circular sealing component with a round cross-section that sits within a machined groove.

When two mating surfaces are brought together:

1. The O-ring compresses.
2. The elastomer deforms slightly.
3. This creates a tight barrier that prevents liquids or gases from escaping.

The natural elasticity of NBR allows it to:

• Compensate for minor surface imperfections
• Maintain sealing performance under pressure
• Recover its shape after compression

This compression sealing principle makes NBR O-rings highly effective in both static and dynamic applications.

Temperature Performance

Our NBR O-rings are suitable for the following temperature ranges:

• Down to: -30°C
• Up to: 90°C (intermittent use)
• Recommended operating range: -20°C to +90°C

Chemical Resistance

NBR offers excellent resistance to:

• Many hydrocarbons
• Fats
• Oils and gasoline
• Petroleum-based hydraulic fluids (HFD-R)

However, NBR is not compatible with:

• Ozone
• Esters
• Ketones
• Aldehydes
• Chlorinated hydrocarbons
• Nitro hydrocarbons

If your application involves any of the above substances, alternative materials may be more suitable. Speak to our team on live chat for alternatives.
