NBR O-Rings (Nitrile)
NBR O-Rings for oil-resistant and general sealing applications, widely used in automotive and industrial systems. Available in standard and custom sizes with OEM manufacturing support.
Product overview
Product details
NBR O-Rings (Nitrile Rubber) are one of the most widely used sealing solutions, known for their excellent resistance to petroleum oils, fuels, and lubricants. They provide a balanced combination of cost efficiency, mechanical performance, and sealing reliability.
These O-rings are ideal for a wide range of industrial applications, including automotive systems, hydraulic and pneumatic systems, and general industrial machinery. We supply both standard and custom NBR O-rings with full OEM manufacturing support.

- Automotive systems (engines, fuel systems, transmissions)
- Hydraulic and pneumatic systems
- Oil and gas equipment
- Industrial machinery
- General sealing applications
Material Advantages
NBR offers a cost-effective balance of performance and durability for oil sealing applications. Compared to FKM, it is more economical for general oil resistance, though it has lower heat and chemical resistance. Compared to EPDM, NBR has superior oil resistance but less resistance to water and steam.
Customization
- Custom inner diameter (ID), outer diameter (OD), and cross section (CS)
- Custom colors for identification or branding
- Custom packaging and private labeling
- Tooling development with fast turnaround
