NBR Seal

NBR Oil Seals for Automotive and Industrial Fluid Sealing

Independence Seal specializes in manufacturing custom NBR seals, combining steel and a lip element. Our steel options include mild (CRS) steel and 304 stainless steel, with NBR (nitrile rubber) as the standard lip material. Our seals offer exceptional durability and resistance to various oils and chemicals. Tailored solutions ensure optimal performance for diverse industrial applications.

About NBR (Nitrile Butadiene Rubber)

NBR belongs to a family of unsaturated synthetic rubbers known for their robustness and versatility. The unique composition of NBR, which can be adjusted by varying the acrylonitrile content, provides it with a range of physical and chemical properties that make it ideal for sealing applications.

Properties of NBR (Nitrile Butadiene Rubber)

• Operating Temperature Range: -20°F to 200°F (can withstand up to 300°F for a short duration)
• Resistance:
  • Excellent resistance to most mineral oils and greases with a mineral oil base
  • Resistant to gasoline, diesel, light heating oil, animal and vegetable oils, and fats
  • Resistant to hot water
• Mechanical Properties:
  • Poor resistance to ozone and impact
  • Very good abrasion resistance
• Hardness:
  • Standard: 75 durometer
  • H1 variant: 85 durometer

Benefits of NBR (Nitrile Butadiene Rubber):

The numerous benefits of NBR make it a preferred material for oil seals:

• Strong Engineering Properties: The robustness and durability of NBR ensure reliable sealing performance in demanding applications.
• Versatile Applications: NBR oil seals are used in hydraulic systems, gas and oil environments, silicone oil systems, and with animal and vegetable oils and fats, as well as in both hot and cold water systems.
• Customizable: The ability to compound NBR for specific needs allows for enhanced performance tailored to particular applications, such as improved aging, flame resistance, and ozone resistance when compounded with PVC.
• Food and Pharmaceutical Suitability: Special potable water (WRC/WRAS) compounds of NBR are safe for use in the food and pharmaceutical industries.
• Military Specifications: NBR-based compounds are used to create fuel and oil-resistant O-rings that meet various military standards.
• Oil Resistance: Seals with high acrylonitrile content offer superior oil resistance, while those with low acrylonitrile content provide better low-temperature flexibility and resilience.
• Low-Temperature Performance: Special low-temperature NBR compounds are available for use with mineral oil-based fluids, ensuring optimal performance in cold environments.
