The Oil & Heat Resistant HNBR O-Ring is made from Hydrogenated Nitrile Butadiene Rubber (HNBR), a tough elastomer known for its outstanding resistance to oil, heat, ozone, and mechanical stress.

HNBR O-rings combine excellent tensile strength and elasticity with superior chemical and thermal stability, making them a preferred choice for applications involving high temperatures, oils, fuels, and dynamic motion.

These seals are widely used in automotive, hydraulic, and industrial equipment, where reliability and long service life are essential.

Features:

• Excellent Oil & Heat Resistance: Stable in mineral oils, fuels, and lubricants.

• Temperature Range: Performs effectively from -30°C to +150°C (up to +165°C intermittently).

• Superior Mechanical Strength: Resists tearing, wear, and compression set.

• Good Chemical Compatibility: Suitable for contact with coolants, industrial fluids, and ozone.

• Custom Production: Available in various hardness (60–90 Shore A), sizes, and colors.

Applications:

• Automotive engines, fuel systems, and air conditioning components

• Hydraulic cylinders, pumps, and valves

• Oilfield and petrochemical equipment

• Industrial compressors and machinery

• Power transmission and sealing systems

Advantages:

• Reliable sealing in dynamic and static environments

• Long service life under extreme temperature and pressure

• Complies with ISO, RoHS, and REACH standards

• OEM/ODM customization available for industrial clients
