The Oil & Heat Resistant HNBR O-Ring is engineered to withstand demanding environments where both high temperature and aggressive fluids are present.
Made from Hydrogenated Nitrile Butadiene Rubber (HNBR), this O-ring delivers exceptional resistance to oils, fuels, and chemicals, while maintaining mechanical strength and elasticity under stress.

HNBR combines the flexibility of standard nitrile rubber (NBR) with enhanced resistance to oxidation, heat aging, and abrasion, making it a reliable choice for long-term sealing in industrial, automotive, and hydraulic systems.

Features:

• Excellent Oil & Heat Resistance: Performs from –30°C to +150°C

• Outstanding Mechanical Strength: Ideal for high-pressure and dynamic sealing

• Superior Chemical & Ozone Resistance for harsh operating conditions

• Low Compression Set: Ensures long-lasting sealing integrity

• Available in Custom Sizes & Hardness Options

Applications:

• Automotive engines, gearboxes, and fuel systems

• Hydraulic and pneumatic sealing systems

• Oil & gas machinery

• Industrial pumps and compressors

• Chemical processing and mechanical equipment

Advantages:

• Long service life under high heat and oil exposure

• Reduced leakage and maintenance costs

• Reliable sealing in dynamic and static applications

• Manufactured under ISO, RoHS, and REACH standards

• OEM and custom design available upon request
