6.07 x 1.78 HNBR O-Ring (50) - S.U.R. and R Auto Parts

The S.U.R. and R Auto Parts HOR140 HNBR O-Ring is engineered for professional technicians and mechanics requiring reliable, high-performance sealing in demanding automotive and industrial environments. This pack of 50 O-rings, sized 6.07 x 1.78 mm, utilizes Hydrogenated Nitrile Butadiene Rubber (HNBR), a superior elastomer known for its enhanced durability and resistance properties over standard NBR. It provides consistent, leak-free performance crucial for maintaining system integrity and operational efficiency.

Key Features

• Advanced HNBR Construction: Manufactured from Hydrogenated Nitrile Butadiene Rubber, offering superior resistance to heat, oils, and chemicals compared to conventional nitrile rubber.
• Exceptional Durability: Features enhanced mechanical strength, flexibility, and abrasion resistance, ensuring a longer service life and reliable sealing under pressure and mechanical stress.
• High-Temperature Performance: Designed to maintain sealing integrity across a wide temperature range, typically from approximately -40°C (-40°F) up to 150°C (300°F) or higher, making it suitable for hot-running systems.
• Chemical and Ozone Resistance: Provides excellent resistance to petroleum-based oils, fuels, refrigerants, and various industrial fluids, as well as improved resistance to ozone and weathering degradation.
• Precision Fit: Each O-ring is manufactured to precise dimensions (6.07 mm ID x 1.78 mm CS) to ensure a secure and effective seal.
• Professional-Grade Quality: Supplied in a pack of 50, these O-rings are built to professional standards, reducing the need for frequent replacements and minimizing downtime in critical applications.

Applications

These HNBR O-rings are ideal for critical sealing applications in both automotive and industrial sectors where exposure to harsh conditions is common.

• Automotive: Essential for sealing in automotive fuel systems, air conditioning systems (compatible with refrigerants like R134a, R401a, R404a, R410a, R507, R744), engine seals, transmission systems, power steering systems, and fuel injectors.
• Industrial: Suited for hydraulic and pneumatic systems, oil and gas equipment, industrial machinery, pumps, valves, compressors, and cylinders, as well as in chemical production and power generation facilities.
