RS PRO Nitrile Rubber (NBR) O-Ring 4.5 mm ID 8.5 mm OD 2 mm Thickness 71 IRHD Hardness 196-4853

RS PRO 196-4853 Nitrile Rubber (NBR) O-Ring is a high-quality sealing component engineered for industrial, mechanical, and fluid power applications. This O-ring features an inside diameter of 4.5 mm, outside diameter of 8.5 mm, and a thickness of 2 mm, manufactured from nitrile rubber with a hardness rating of 71 IRHD. It is designed to provide excellent sealing performance and durability in environments exposed to oils, greases, and vegetable oils.

The nitrile rubber material delivers superior resistance to chemicals and wear, ensuring a long service life. This O-ring operates effectively within a temperature range of -30°C to 90°C, making it suitable for use in hydraulic and pneumatic systems, pumps, drive belts, and other general engineering uses.

In typical applications, O-rings serve as essential seals that prevent the passage of fluids or air between mating parts. When compressed, this circular seal creates a strong barrier that protects systems from leaks, maintains pressure, and excludes contaminants. The RS PRO nitrile O-ring is especially ideal where robust resistance to oils, fuel, and most hydrocarbons is required.

Available in metric sizes, this O-ring’s black color and standard dimensions make it compatible with a wide variety of industrial sealing needs. The 71 IRHD hardness rating balances flexibility and strength, permitting use in dynamic and static sealing configurations including shaft seals and face-to-face seals allowing rotary and linear motion.

The O-ring is constructed from nitrile rubber (NBR) with 71 IRHD hardness. Dimensions: 4.5 mm inside diameter, 8.5 mm outside diameter, 2 mm thickness. Operating temperature range: -30°C to 90°C. Resistant to fats, greases, vegetable oils, hydrocarbons, oils, and fuels.

Suitable for sealing in hydraulic, pneumatic, pump, and drive belt applications. Provides long-lasting, durable sealing performance in industrial environments. Versatile use in rotary and linear motion sealing scenarios.

This RS PRO O-Ring is a reliable choice for manufacturing, maintenance, and repair in automotive, industrial machinery, fluid power, and many other sectors requiring high-quality seals. Their performance under demanding conditions assures minimal downtime and reliable operation.
