Why Choose Nitrile (NBR) Rubber?
Nitrile rubber is specifically formulated for environments where oil and fuel contact is unavoidable:
- Petrol & Diesel Resistant – Won't swell or degrade with fuel exposure
- Oil & Grease Proof – Ideal for engine bays and workshops
- Hydraulic Fluid Compatible – Seals hydraulic systems safely
- Wide Temperature Range – Performs from -30°C to +100°C
- Excellent Abrasion Resistance – Long-lasting in wear applications

- 🏭 Hydraulic Seals – Pump and cylinder seals
- ✈️ Aerospace – Fuel system components
- 🚜 Agricultural Machinery – Diesel engine gaskets
- 🔩 Industrial Equipment – Oil-resistant washers and grommets
When to Choose Nitrile Rubber
Choose nitrile (NBR) when your application involves:
- Contact with petrol, diesel, or aviation fuel
- Exposure to engine oils, gear oils, or hydraulic fluids
- Grease and petroleum-based lubricants
- Operating temperatures up to 100°C
Avoid nitrile for outdoor/UV exposure, ozone contact, or polar solvents (ketones, esters) – choose EPDM or Neoprene instead.
Frequently Asked Questions
Is nitrile rubber suitable for fuel tank gaskets?
Yes, nitrile (NBR) is the industry standard for fuel system gaskets. It resists petrol, diesel, biodiesel, and aviation fuels without swelling or degrading. Our 3mm thickness is ideal for fuel tank flanges and sender unit gaskets.
What's the difference between Nitrile and Viton?
Both resist oils and fuels, but Viton (FKM) handles higher temperatures (up to 200°C) and more aggressive chemicals. Nitrile is more cost-effective for standard automotive and industrial applications up to 100°C. Choose Viton for extreme heat or aggressive fuel blends.
Can nitrile rubber be used outdoors?
Nitrile has poor UV and ozone resistance, so it's not recommended for prolonged outdoor exposure. For outdoor applications, EPDM rubber is a better choice. Nitrile excels in covered/indoor environments where oil and fuel resistance is the priority.
How do I cut nitrile rubber sheet for gaskets?
Nitrile cuts cleanly with a sharp Stanley knife and straight edge. For circular gaskets, use a gasket cutter or hole punch set. For production quantities, die cutting is most efficient. The material cuts easier than natural rubber due to its composition.
What is the shelf life of nitrile rubber?
Stored properly (cool, dry, away from UV light), nitrile rubber has a shelf life of 5-10 years. We cut from fresh stock, not old warehouse material, ensuring you receive rubber with maximum remaining service life.
