WHERE TO USE NBR O RINGS: IDEAL APPLICATIONS
NBR O Rings (Nitrile Butadiene Rubber O Rings) are the versatile sealing workhorse in industrial and automotive fields. Their excellent oil resistance and cost-effectiveness make them the preferred solution for applications involving petroleum-based media.
1. Automotive & Transportation
- Fuel Systems: Fuel pumps, injector lines, fuel tank seals.
- Engine Systems: Oil filters, oil pan gaskets, cooling system components (in contact with water).
- Braking Systems: Auxiliary seals for some brake fluids (e.g., DOT3, DOT4) (compatibility must be verified).
- Transmission & Chassis: Power steering systems, shock absorbers.
2. Hydraulic & Pneumatic Systems
- Hydraulic Equipment: Hydraulic cylinders, valves, pumps, connectors (suitable for mineral oil-based hydraulic fluids).
- Pneumatic Tools: Cylinders, pneumatic wrenches, control systems (sealing air, inert gases).
3. General Industry & Manufacturing
- Pumps & Compressors: Lubricating oil seals, cooling water seals.
- Drive Units: Gearboxes, bearing seals.
- Chemical Processing: Sealing water, glycol, certain lubricants and other mild chemicals (avoid strong oxidizers, ketones, esters).
- Home Appliances: Water pump seals for washing machines, dishwashers.
4. Everyday Equipment
- Fuel nozzles, oil cans, lubricant dispensing equipment.
- Hydraulic and fuel components of agricultural machinery.
SCENARIO SUMMARY
NBR O Rings are typically an economical and reliable choice when your application involves mineral oils, lubricants, fuels, water, or compressed air, and operates within a temperature range of -55°C to +135°C.
