High-Performance Nitrile Rubber BS2751 Gaskets for Industrial Applications
Stephens Gaskets manufactures premium nitrile rubber BS2751 gaskets designed for demanding environments where sealing performance is critical. With more than 70 years of experience supplying gaskets, shims and washers to UK and global industries, we understand the level of reliability required when equipment operates in oil-rich or chemically aggressive settings.
Nitrile rubber (also known as Buna-N) remains one of the most widely used gasket materials thanks to its excellent resistance to oils, fuels and a range of industrial chemicals.
What Makes Nitrile Rubber BS2751 Gaskets Unique?
Nitrile gaskets manufactured to the BS2751 standard provide dependable sealing performance in environments exposed to petroleum-based fluids and solvents. These gaskets are engineered for durability, flexibility and long-term stability, making them suitable for critical sealing applications in machinery, pipework and fuel systems.
Key performance attributes include:
1. Outstanding Oil & Fuel Resistance
Nitrile rubber withstands petrol, diesel, lubricants and hydrocarbons, ensuring secure sealing in environments where other rubbers may degrade.
2. Wide Temperature Range
Operational effectiveness from -30°C to +120°C provides confidence across both cold-start and high-heat conditions.
3. Chemical Resistance
Nitrile offers strong resistance to many industrial chemicals and solvents, supporting reliable performance in chemically active environments.
4. Durability & Mechanical Strength
Its resilience makes nitrile suitable for continuous use under pressure, vibration and mechanical stress.
5. Cost-Effective Material Choice
Compared with specialist rubbers such as Viton® or silicone, nitrile offers impressive performance at a competitive price.

Limitations of Nitrile Rubber – What Buyers Should Know
While nitrile rubber offers excellent performance in many environments, there are limitations to consider:
- Not suitable for extreme heat above 120°C.
- Vulnerable to UV and ozone, making it less suitable for prolonged outdoor exposure.
- Not resistant to certain chemicals such as ketones, esters and chlorinated hydrocarbons.
- Can experience compression set over long periods under heavy pressure.
- Gradual hardening may occur when exposed to heat or oil for extended durations.
Understanding these factors ensures the right material is selected based on the application.
