Nitrile Rubber Gaskets (NBR) – Oil-Resistant Sealing for Demanding Applications
Kaxite Sealing manufactures high-performance nitrile rubber gaskets (NBR gaskets) engineered for superior sealing in oil, fuel, and hydrocarbon environments. Nitrile-butadiene rubber (NBR) is the material of choice for applications requiring excellent oil resistance, abrasion resistance, and anti-aging properties – making it ideal for automotive, petrochemical, hydraulic, and industrial sealing applications where exposure to petroleum-based fluids is unavoidable.
What sets Kaxite apart? Our NBR gaskets are manufactured using precision compression moulding and automated die-cutting technologies, ensuring consistent dimensional accuracy and surface finish across every batch. We source premium nitrile compounds from certified suppliers, and each production lot undergoes rigorous quality testing – including hardness (Shore A), tensile strength, elongation, and oil immersion tests – to guarantee reliable sealing performance in your most demanding applications. Our ISO 9001:2015 certified facility ensures every gasket meets the highest quality standards.
With our custom OEM/ODM capabilities, we supply NBR gaskets in virtually any size, thickness, and configuration – from standard ANSI/ASME flange gaskets to custom-designed shapes for specialised equipment. Whether you need bulk wholesale quantities for maintenance inventory or just-in-time delivery for project deadlines, Kaxite Sealing is your trusted rubber gaskets manufacturer.

Frequently Asked Questions
- Q: What is NBR (nitrile) rubber and why is it used for gaskets?
- A: NBR (Nitrile-Butadiene Rubber) is a synthetic rubber copolymer known for exceptional resistance to petroleum-based oils, fuels, hydraulic fluids, and greases. It also offers excellent abrasion resistance, anti-aging properties, and air tightness – making it the preferred material for automotive, petrochemical, hydraulic, and industrial sealing applications where oil exposure is a concern. NBR is not recommended for ketones, esters, or chlorinated hydrocarbons.
- Q: What temperature range can NBR gaskets handle?
- A: Standard NBR gaskets operate continuously from –30 °C to +120 °C. For higher temperature applications (up to +250 °C), we recommend FKM (Viton) gaskets. For low-temperature applications down to –70 °C, consider silicone gaskets.
- Q: What sizes and thicknesses are available for NBR gaskets?
- A: We manufacture NBR gaskets in virtually any size and thickness (1.0 – 25.0 mm). We can produce gaskets to ANSI/ASME, DIN, BS, JIS, or custom flange specifications. Contact us with your requirements for a quick quote.
- Q: Are NBR gaskets suitable for fuel and oil applications?
- A: Yes. NBR gaskets offer excellent resistance to petroleum-based oils, fuels, hydraulic fluids, and greases. They are widely used in automotive engines, fuel systems, hydraulic equipment, and petrochemical applications. However, NBR is not compatible with ketones, esters, or chlorinated hydrocarbons.
- Q: What is the typical lead time for custom NBR gaskets?
- A: Standard sizes: 7–15 working days. Custom dimensions: 15–25 working days, depending on order volume and complexity. Expedited production is available for urgent requirements – request a quote for specific delivery timelines.
- Q: Do you provide samples before bulk orders?
- A: Absolutely. We supply free material samples for you to evaluate quality, oil resistance, and sealing performance on your specific applications. Request a free sample – sample orders are processed within 3–5 working days.
