NBR70 O-Ring | O Ring Seal | Oil-Resistant Industrial Seal

Product Description

This GSK HNBR O-Ring (P/N: 281518775) is a high-performance sealing component made from tested hydrogenated nitrile butadiene rubber. Engineered for demanding oil-contact environments, it delivers reliable sealing between -40°C and 150°C, with excellent 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 machinery, creating a durable barrier against fluid leakage. Its tested HNBR material offers superior anti-aging and compression set resistance, ensuring long-term performance even under dynamic operating conditions.

Advantages

Proven Performance: TESTED certification ensures consistent quality and reliability for critical sealing applications.
Superior Oil & Heat Resistance: HNBR 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.
Universal Compatibility: Standard circular cross-section fits most equipment seal grooves, enabling direct installation.
Dynamic Sealing Capability: Maintains integrity under pressure fluctuations and movement, ideal for hydraulic and automotive systems.

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 machinery from dust and moisture, extending component lifespan in harsh environments.
Reduces vibration transmission between mating surfaces, improving equipment stability and reducing noise.
Ensures leak-proof performance in gearboxes and transmissions, supporting smooth vehicle operation.
