Nitrile rubber (NBR) seals are widely used in the following fields due to their excellent oil resistance, wear resistance, and heat resistance:
1. Automotive Industry
Fuel system: fuel pumps, injectors, fuel tank seals (resistant to gasoline and diesel).
Hydraulic systems: Sealing for brake fluid, transmission fluid, and power steering fluid. Engine peripherals: Crankshaft oil seals, valve stem seals, etc. (resistant to engine oil and lubricating oil).
2. Petroleum and Chemical Industry
Oil pipelines: Sealing for valves and pump bodies (resistant to mineral oil and hydrocarbon solvents).
Chemical Equipment: Seals exposed to acids, alkalis, and other media (NBR formulations must be selected based on specific chemicals).
3. Hydraulic and Pneumatic Systems
Hydraulic Cylinders/Pneumatic Cylinders: Piston rod seals, O-rings (resistant to hydraulic oil, water-glycol, etc.). Construction Machinery: Hydraulic seals for excavators, forklifts, and other equipment.
4. Home Appliances and Electronics
Washing machines/dishwashers: Water seals, drain valve seals (resistant to water and detergents).
Refrigeration equipment: Refrigerant (e.g., R134a) seals (requires NBR with good low-temperature performance).
5. Aerospace
Fuel and hydraulic systems: Aircraft fuel tank and hydraulic line seals (requires high-grade NBR material).
6. Food and Pharmaceuticals
Food machinery: Seals for edible oils and fats (requiring food-grade NBR compliant with FDA standards). Pharmaceutical equipment: Seals in non-sterile environments (e.g., lubrication points).
7. Other Industrial Applications
Water treatment: Water-resistant and wear-resistant seals for pumps. Mining equipment: Seals resistant to slurry and dust.
