O-ring from NBR rubber, lower than 68 Sh
NBR (nitrile butadiene rubber) O-rings are among the most popular sealing solutions, especially in applications requiring contact with oils and fuels. These NBR O-rings have a hardness below 68 Shore A (Sh), making them more flexible and better suited to conform to sealing surfaces.
Characteristics of NBR O-Rings lower than 68 Sh
Excellent Oil Resistance
NBR material effectively resists oils, greases, and fuels, making it an ideal choice for engines and hydraulic systems.
More Flexible
O-rings with <68 Sh hardness offer greater flexibility, ensuring better sealing and easier installation, especially on irregular sealing surfaces.
Good Mechanical Properties
NBR O-rings withstand mechanical stress and wear well, ensuring long service life.
Wide Temperature Range
NBR O-rings perform reliably across a broad temperature range (-30°C to +100°C).
