RS PRO Nitrile Rubber (NBR) O-Ring, 41 mm ID, 49 mm OD, Black, 71 IRHD Hardness, 196-5124

The RS PRO 196-5124 Nitrile Rubber (NBR) O-Ring is engineered to deliver robust sealing in a variety of industrial and engineering applications. This O-ring features an inner diameter of 41 mm and an outer diameter of 49 mm, making it compatible with metric-based components commonly used in machinery, pipelines, and fluid systems.

Manufactured from high-quality Nitrile Rubber (NBR), this O-ring stands out for its excellent resistance to oils, hydrocarbons, fuels, and various lubricants. NBR is widely recognized for its durability and affordability, making it the rubber of choice for applications where exposure to greases and vegetable oils is expected. The O-ring is colored black and exhibits a hardness rating of 71 IRHD, providing the optimal balance between flexibility and form stability.

This O-ring operates efficiently across a broad temperature range of -30°C to 90°C. It is designed to withstand the requirements of demanding hydraulic and pneumatic systems, where sealing reliability and prevention of leakage are critical for maintaining pressure integrity and operational safety.

The RS PRO NBR O-Ring is suitable for use as shaft seals, face-to-face seals, and for supporting both rotary and linear movement in mechanical assemblies. Its metric dimensions enable universal compatibility in standard industrial, manufacturing, and engineering settings. Applications extend to hydraulics, pneumatic equipment, automotive production and repair, plumbing, and power transmission technology.

When compressed between two components, the O-ring forms a secure barrier against particles, vapors, and fluid leakage, ensuring uninterrupted machinery function and reduced risk of contamination. This prolongs system life and helps maintain precise operating conditions within the assembly. Under the correct conditions and with suitable material selection, NBR O-rings like this model can deliver a service life of up to 15 years, minimizing maintenance needs over time.

It is advised to avoid using this O-ring with certain chemicals, including ozone, esters, retone, aldehydes, chlorinated substances, or nitro hydrocarbons, as they may compromise the elastomer's longevity and effectiveness.

This RS PRO O-ring is a trusted component among industrial automation professionals, engineers, and maintenance specialists where reliable, efficient sealing is a necessity.
