HNBR65K Washer | Rubber Gasket | 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.

Product Name
HNBR70K O-Ring
Part Number
281518765
Material
HNBR65K (Hydrogenated Nitrile Butadiene Rubber), black
Superior Oil & Heat Resistance: HNBR65K 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 washers.
Vibration Damping & Sealing: Flat design absorbs mechanical vibration and creates a tight seal, preventing fluid leakage and reducing equipment noise.
Universal Compatibility: Standard central hole fits most bolt sizes, enabling direct installation in automotive and industrial assemblies.
Consistent Performance: Precision dimensions and high-grade material ensure reliable sealing and damping in harsh operating environments.
Applications:
Seals automotive engine bolt assemblies and oil pan interfaces to prevent oil leakage and maintain lubrication efficiency.
Reduces vibration transmission in hydraulic system valve blocks and pump mounts, improving equipment stability.
Provides a damping layer between metal components in industrial machinery, minimizing wear and operational noise.
Creates a dust and moisture barrier for mechanical enclosures, protecting internal components from contaminants.
Ensures leak-proof performance in gearbox and transmission fasteners, supporting smooth vehicle operation.
