NBR Rubber Parts for Automotive Sealing Applications
At Xingtai Guanghua Rubber Products Co., Ltd. , we manufacture a full range of NBR rubber parts designed for reliable sealing and protection in automotive applications. NBR (Nitrile Butadiene Rubber) is one of the most widely used elastomer materials in the automotive industry due to its excellent resistance to oil , fuel , and grease .
NBR rubber offers a balanced combination of mechanical strength , wear resistance , and cost efficiency , making it an ideal choice for both OEM production and aftermarket replacement parts requiring stable sealing performance under dynamic conditions.
Our automotive-grade NBR materials are suitable for operating environments involving moderate temperatures (-40°C to +120°C), oil exposure , and continuous movement . Choosing NBR rubber parts ensures:
- Effective oil and fuel sealing with minimal leakage risk
- Stable performance under vibration and mechanical stress
- Good abrasion resistance for moving components
- Cost-effective solutions for high-volume production
- Excellent compression set resistance for long-term sealing integrity
Our NBR compounds are available in various hardness grades (Shore A 40-90) to match specific application requirements, from flexible boots requiring high elasticity to rigid seals demanding dimensional stability.
We supply custom-molded NBR rubber parts widely used in O-rings , rubber sealing rings , CV joint boots , driveshaft boots , steering rack boots , shock absorber dust covers , stabilizer bushings , and other automotive sealing components.
All NBR products undergo strict quality control including hardness testing, tensile strength measurement, and oil resistance verification to ensure consistent performance across production batches and meet international automotive standards such as ISO 9001 and IATF 16949 requirements.

Frequently Asked Questions About NBR Rubber Parts
Common questions about NBR rubber materials, applications, customization, and bulk supply.
What are NBR rubber parts commonly used for?
NBR rubber parts are widely used in automotive sealing applications where resistance to oil, fuel, and grease is required. Common uses include O-rings, rubber sealing rings, CV joint boots, driveshaft boots, steering rack boots, and hydraulic seals.
Is NBR rubber suitable for automotive oil sealing applications?
Yes. NBR (Nitrile Butadiene Rubber) offers excellent resistance to engine oil, transmission fluid, fuel, and grease, making it one of the most commonly used materials for automotive oil sealing components.
What temperature range can NBR rubber parts handle?
Standard automotive-grade NBR rubber typically operates within a temperature range of approximately -30°C to +100°C . Modified NBR compounds can be formulated to meet specific temperature and performance requirements.
How does NBR compare with FKM (Viton) rubber?
NBR rubber is more cost-effective and suitable for moderate temperature oil sealing applications, while FKM (Viton) rubber provides superior heat and chemical resistance for high-temperature environments. The choice depends on operating conditions and budget requirements.
Do you offer custom NBR rubber parts for OEM projects?
Yes. We provide OEM and ODM services for custom NBR rubber parts, including material formulation, hardness control, dimension customization, and mold development based on drawings or samples.
What is your minimum order quantity (MOQ) for NBR rubber parts?
MOQ depends on product type, size, and customization level. Standard NBR rubber parts support bulk production, while custom-molded parts typically require a higher MOQ. Please contact us for project-specific details.
How do you ensure the quality of NBR rubber parts?
We implement strict quality control throughout raw material selection, mixing, molding, and final inspection. All NBR rubber parts are tested for dimensional accuracy, hardness, and sealing performance to meet automotive standards.
