Gas-approved nitrile rubber is a high-performance elastomer designed specifically for gas-related sealing applications.
What Is Gas-Approved Nitrile Rubber?
Compliant with BS EN 682:2002, this material meets strict safety and durability requirements for seals, gaskets, and diaphragms used in contact with natural gas, LPG (liquefied petroleum gas), and hydrocarbons.
BS EN 682:2002 ensures that the material:
- Prevents gas leaks with excellent sealing properties.
- Resists degradation when exposed to hydrocarbons and lubricants.
- Maintains performance under extreme temperatures and pressures.
- Ensures long-term reliability in gas transmission, storage, and appliances.
This makes nitrile rubber (NBR) the preferred material for gas meters, pipelines, and heating appliances.
Key Properties of BS EN 682:2002-Compliant Nitrile Rubber
- Superior Chemical Resistance: Withstands exposure to natural gas, LPG, oils, and lubricants.
- High-Temperature Stability: Operates efficiently across extreme temperature variations.
- Low Compression Set: Retains elasticity and shape to ensure long-term sealing.
- Excellent Durability: Resistant to aging, cracking, and wear over extended use.
- Leak Prevention: Forms an airtight and secure seal, minimizing gas leakage risks.
- Meets Industry Standards: Fully compliant with BS EN 682:2002, ensuring safety and reliability.

Challenges & Solutions for Gas-Approved Nitrile Rubber
1. Temperature Limitations
- Challenge: Standard nitrile rubber may degrade at temperatures above 120°C.
- Solution: For high-temperature applications, consider Viton® (FKM) or silicone rubber.
2. Aging & Environmental Exposure
- Challenge: UV and ozone exposure can cause surface cracking in outdoor environments.
- Solution: Use ozone-resistant or coated nitrile rubber for extended outdoor use.
3. Compression Set Over Time
- Challenge: Repeated compression may reduce elasticity, impacting sealing efficiency.
- Solution: Regular maintenance and using low-compression-set nitrile variants can improve longevity.
4. Compatibility with Harsh Chemicals
- Challenge: Nitrile rubber is less resistant to strong acids or ketones.
- Solution: For aggressive chemicals, PTFE or EPDM may be better alternatives.
5. Cost of Compliance
- Challenge: BS EN 682:2002-certified materials cost more than standard rubbers.
- Solution: The long-term safety and durability benefits outweigh the initial investment.
