HNBR O-Rings

HNBR O-Rings (Hydrogenated Nitrile Rubber) are designed for demanding environments requiring high temperature resistance and excellent oil compatibility. They provide improved mechanical strength and durability compared to standard NBR.

These O-rings are widely used in automotive and industrial systems for sealing applications involving petroleum oils, fuels, and aggressive media.

Key Features

• Excellent oil and fuel resistance
• High temperature stability compared to NBR
• Superior mechanical strength and abrasion resistance
• Good resistance to wear and compression set
• Suitable for dynamic and high-pressure sealing applications

Technical Specifications

• Material: HNBR (Hydrogenated Nitrile Rubber)
• Temperature Range: -40°C to +150°C (up to 165°C short-term)
• Color: Black, green, or custom
• Application: Static and dynamic sealing
• Certification: ISO / RoHS / REACH available

Size Range

Standard sizes available with custom inner diameter (ID), outer diameter (OD), and cross section (CS). Contact us for specific size requirements.

Applications

• Automotive systems (engine seals, fuel systems, AC systems)
• Oil and gas equipment
• Hydraulic and pneumatic systems
• Industrial machinery
• Heavy-duty equipment

Material Advantages

HNBR offers significantly better heat resistance, strength, and durability than standard NBR, and better oil and fuel resistance than EPDM. It is more cost-effective than FKM for medium-high performance applications.

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
