Custom NBR Rubber Strip
NBR Rubber Seal Strip Manufacturer
As an experienced rubber parts manufacturer, Flexiparts produces custom NBR rubber seal strips designed for oil-resistant sealing applications. NBR compounds provide excellent resistance to petroleum-based fluids, abrasion, and mechanical wear, making them ideal for hydraulic systems, automotive components, and industrial equipment.
Send us your drawing or sample — we customize the profile, hardness, and rubber formulation to match your application, from initial prototypes to full-scale production.
Custom NBR Rubber Seal Strip Capabilities
NBR compounds are selected based on fluid exposure, temperature range, and sealing performance requirements. We customize rubber strips for different industrial applications.
| Parameter | Our Capability |
| Profile shape | Flat, D, P, U, bulb, sponge profiles, or custom shapes from drawings/samples |
| Hardness (Shore A) | 40–90 Shore A |
| Width / Thickness | Width up to 500 mm; thickness from 1 mm to 50 mm |
| Construction | Solid rubber, sponge rubber, or foam rubber |
| Compound selection | Standard NBR or custom formulation based on oil, fuel, and chemical exposure |
| ACN content | Selected according to required oil resistance and temperature performance |
| Color | Black standard; other colors available depending on compound requirements |
| Temperature resistance | Approx. -30°C to +120°C (-22°F to +248°F), depending on formulation |
| Adhesive backing | Available upon request |
Why Choose Our NBR Rubber Seal Strip Manufacturing
Application-Based Compound Selection
NBR performance depends on the rubber formulation. We select compounds based on your actual operating conditions, including oil type, fuel exposure, temperature, and sealing requirements.
Match Existing Rubber Parts
Have an existing seal strip without drawings? Send us a sample. We can measure the profile, hardness, and dimensions to develop a replacement solution.
Prototype Before Mass Production
Samples can be produced for validation before full production, helping confirm sealing performance and installation fit.
Flexible OEM Production
From simple sealing strips to custom profiles, we support low-volume prototypes and repeat production orders with consistent quality.
Choose NBR or Another Rubber Material?
Choose NBR Rubber Seal Strip When:
- Contact with oil, fuel, grease, or hydraulic fluid is expected
- Good abrasion resistance is required
- The sealing environment involves industrial lubricants
- Cost-effective oil resistance is needed
Consider Another Material When:
Long-term outdoor exposure, UV, ozone, and weather resistance are the priority → Choose EPDM Rubber Strip
Extreme temperature or chemical resistance is required → Consider FKM Rubber Seal Strip
Food, medical, or high-temperature applications are required → Consider Silicone Rubber Seal Strip
Typical Applications
Custom NBR rubber seal strips are commonly used for:
- Hydraulic equipment sealing
- Automotive and engine components
- Fuel system sealing
- Industrial machinery
- Oil tanks and pipelines
- Mechanical enclosures and protective seals
FAQ About NBR Rubber Seal Strip
1. What ACN content do I need for my NBR rubber strip?
ACN selection depends on the fluid type, operating temperature, and required oil resistance. Send your application details, and we can recommend a suitable NBR compound.
2. Can NBR rubber strips be used outdoors?
NBR can handle limited outdoor exposure, but it is not the preferred choice for long-term UV and ozone exposure. For weather-dominant applications, EPDM is usually a better option.
3. Can you manufacture NBR seal strips from an existing sample?
Yes. We can measure your existing sample, confirm the profile and hardness requirements, and manufacture replacement parts.
4. What is the MOQ for custom NBR rubber seal strips?
MOQ typically starts from 100–500 meters, depending on profile complexity, tooling requirements, and production setup.
5. What is the sample lead time?
Custom samples are usually available within 15-21 business days after drawing confirmation and production preparation.
