Harltex EN 682 Gas NBR Rubber – Nitrile rubber
EN 682 NBR, also known as nitrile rubber or Buna-N, is widely used where resistance to oils, fuels and hydrocarbons is required.
EN 682 Gas NBR, also known as Buna-N, is a synthetic rubber made from acrylonitrile and butadiene.
Because it is valued for its oil resistance, durability, and cost-effectiveness, this makes it one of the most widely used elastomers across industries.
• Adjustable formulation for oil/fuel resistance or low-temperature flexibility
• Proven in demanding environments for over 70 years.
• Available in standard, food-grade, and specialty grades
Key Features
✔ Excellent resistance to oils, fuels, hydrocarbons
✔ Good mechanical strength & abrasion resistance
✔ Moderate temperature range: –30 °C to +120 °C
✔ Reliable sealing with good compression set resistance
✔ Full range available & cost-effective solutions
Applications – Seals, Gaskets, O-Rings and Hoses
NBR is a versatile elastomer used across industries where oil, fuel, and chemical resistance are essential. From seals, gaskets, hoses, and diaphragms in automotive and industrial systems to fuel system and components in aerospace, EN 682 Gas NBR delivers proven durability and performance in demanding environments.
Industrial & Automotive
- O-rings, gaskets, seals
- Fuel & oil hoses, hydraulic systems.
- Diaphragms, membranes, pump components
Protective & Consumer
- Conveyor belts, rollers, footwear, coatings
Aerospace & Specialty
- Fuel system seals and hoses
Beyond Sealing: Wider Applications for NBR
While O-rings and gaskets are the most common uses of NBR is a material suited to much broader applications. For example:
- Automotive – hoses, diaphragms, and fuel system components.
- Aerospace – fluid transfer systems, engine components, and insulation materials.
- Industrial Processing – chemical-resistant linings, expansion joints, and valve components.
- Energy & Oil/Gas – seals, packers, and parts exposed to aggressive hydrocarbons and sour gas.
- Consumer Products – high-performance rubber parts in electronics and appliances requiring heat and chemical resistance.
Therefore, EN 682 Gas NBR is a versatile material across multiple sectors.
