HNBR Hydrogenated Nitrile O-Ring | O Ring Seal | Oil-Resistant Seal for Engines

Product Description

This HNBR Hydrogenated Nitrile O-Ring, with a size of 9.2x1.2mm, is a high-performance sealing component engineered for harsh operating conditions. Crafted from HNBR70 material, it undergoes a specialized hydrogenation process to enhance molecular stability, delivering superior oil resistance, high-temperature tolerance, and anti-aging properties compared to standard NBR. It maintains consistent sealing performance between -40℃ and 150℃, effectively preventing leakage of mineral oils, synthetic lubricants, and gaseous media. Its black, one-piece circular cross-section design fits standard seal grooves in most industrial equipment, making it particularly suitable for automotive engines, gearboxes, and other applications demanding exceptional sealing reliability, providing long-lasting protection for powertrain systems.

advantages:

Superior Oil & Temperature Resistance:HNBR material exhibits excellent tolerance to mineral oils, hydraulic fluids, and synthetic lubricants, maintaining stable sealing performance at 150℃ and withstanding peak temperatures up to 170℃, meeting the demands of high-temperature environments like automotive engines. 2. Exceptional Aging & Corrosion Resistance:Boasting outstanding ozone and chemical corrosion resistance, it resists hardening and cracking in humid, acidic, or alkaline environments, offering a service life 2-3 times longer than standard NBR and significantly reducing maintenance frequency and costs. 3. High Sealing Reliability:The uniform circular cross-section design delivers balanced sealing pressure in both static and dynamic conditions, effectively preventing medium leakage even during equipment startup/shutdown or pressure fluctuations, ensuring system stability. 4. Long-Lasting Elasticity:Hydrogenation-optimized molecular structure enhances compression set resistance, maintaining excellent resilience after prolonged compression and preventing equipment failures caused by seal degradation. 5. Universal & Easy Installation:Standard dimensions fit seal grooves in most industrial equipment, enabling quick installation without additional machining or customization, offering broad compatibility and reducing project timelines and costs.

Applications:

In automotive engines, it seals valve covers, oil pans, and oil filter interfaces to prevent engine oil leakage, avoiding wear and performance degradation caused by oil loss.
As an oil seal in gearboxes and differentials, it blocks gear oil from external contaminants, ensuring lubrication efficiency and extending the lifespan of gear components.
Provides dynamic sealing for hydraulic system valve blocks, cylinders, and pumps, preventing hydraulic oil leakage, maintaining system pressure stability, and ensuring precise operation of construction machinery and industrial equipment.
Used in motor housings and battery cooling circuits of new energy vehicles, it seals coolant and lubricating grease to protect electrical components from liquid damage, enhancing system safety and durability.
Suitable for high-pressure components like pumps and motors in construction machinery, it withstands frequent pressure shocks and mechanical vibrations, providing reliable sealing for continuous operation in harsh conditions.
