Description

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.

TECHNICAL PARAMETERS


Category Details
Product Name HNBR70K O-Ring
Part Number 281518765
Material HNBR65K (Hydrogenated Nitrile Butadiene Rubber), black
Color Black
Core Functions Sealing, vibration damping, oil resistance, anti-aging
Design Feature Flat washer-style circular design with central hole
Application Automotive engines, hydraulic systems, industrial pumps, mechanical assemblies

Advantages

  • 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.
