HNBR70K O-Ring | O Ring Seal | High-Temp Oil-Resistant Seal

Product Description

This HNBR70K O-Ring, sized 19x2.6mm, is a high-performance sealing component engineered for demanding oil-contact environments. Made from hydrogenated nitrile butadiene rubber, it delivers reliable sealing between -40°C and 150°C, with superior resistance to mineral oils, hydraulic fluids, and ozone. The black, one-piece circular design fits standard seal grooves in automotive engines, hydraulic valves, and industrial pumps, creating a durable barrier against fluid leakage. Its HNBR70K material offers exceptional anti-aging and compression set resistance, ensuring long-term performance even under dynamic operating conditions, making it ideal for critical sealing applications.

Advantages

Superior Oil & Heat Resistance: HNBR70K withstands -40°C to 150°C, resisting mineral oils and hydraulic fluids better than standard NBR.
Anti-Aging & Durability: Resists ozone, oxidation, and compression set, extending service life by 2–3 times compared to NBR.
Dynamic Sealing Capability: Maintains integrity under pressure fluctuations and movement, suitable for hydraulic and automotive systems.
Universal Compatibility: Standard circular cross-section fits most equipment seal grooves, enabling direct installation.
Consistent Quality: Precision dimensions and high-grade material ensure reliable performance in harsh industrial environments.

Applications:

Seals automotive engine oil pans and valve covers to prevent oil leakage and maintain lubrication efficiency.
Provides dynamic sealing for hydraulic cylinders and pumps, preventing fluid loss and stabilizing system pressure.
Protects industrial pumps and compressors from abrasive wear, extending equipment uptime.
Reduces vibration transmission between mating surfaces, improving equipment stability and reducing noise.
Ensures leak-proof performance in gearboxes and transmissions, supporting smooth vehicle operation.
