RS PRO Nitrile Rubber (NBR) O-Ring, 47 mm ID, 55 mm OD, 4 mm Thickness, 71 IRHD Hardness 196-5146

RS PRO 196-5146 Nitrile Rubber (NBR) O-Ring is a precision-engineered sealing component with an inside diameter of 47 mm, outside diameter of 55 mm, and thickness of 4 mm, designed for demanding industrial applications. Manufactured from nitrile rubber, this O-ring combines cost-efficiency with excellent resistance to fats, greases, and vegetable oils, making it highly suitable for hydraulic, pneumatic, and general engineering uses.

The O-ring features a hardness of 71 IRHD, which provides a durable and hardwearing seal capable of withstanding mechanical wear and chemical exposure. It operates reliably within a temperature range from -30°C to 90°C, ensuring performance consistency in various environments encountered in industrial, manufacturing, automotive repair, and power transmission systems.

Commonly used to create effective seals in pumps, drive belts, and other equipment, this NBR O-ring helps prevent fluid and air leakage, maintaining pressure integrity and safeguarding machinery. Its black coloration improves UV resistance and aids in visual inspection.

This versatile O-ring supports both rotary and linear motion sealing, making it suitable for face-to-face and shaft seal applications. When used within specified conditions, it can provide a service life of up to 15 years, offering excellent value and reliability.

It is important to note that this O-ring is not compatible with ozone, esters, retones, or aldehydes, and therefore should be selected accordingly to prevent premature failure. Cost-effective nitrile rubber material provides chemical resistance to oils and fuels.

Hardness of 71 IRHD ensures a long-lasting, wear-resistant seal. Wide operating temperature range from -30°C to 90°C. Application in hydraulic, pneumatic, automotive, and power transmission industries. Design suits rotary and linear sealing movements.

Black color improves durability and makes inspection easier. Good resistance to fats, greases, and vegetable oils. Prevents fluid and air leakage ensuring system efficiency. Not suitable for use with ozone, esters, retones, or aldehydes.
