RS PRO Nitrile Rubber (NBR) O-Ring, Black, 14mm ID, 17.56mm OD, 1.78mm Thickness, AS568-15, 196-4738

RS PRO 196-4738 is a premium nitrile rubber (NBR) O-Ring engineered for use as a high-performance sealing element in hydraulic, pneumatic, and mechanical applications. With a 14mm inside diameter, 17.56mm outside diameter, and 1.78mm cross-sectional thickness, this O-Ring delivers optimal reliability in settings requiring resistance to oils, chemicals, and abrasion. Its black nitrile construction ensures durability and compatibility with a wide range of industrial fluids, making it suitable for pumps, drive belts, fluid systems, and power transmission assemblies.

Designed in accordance with AS568-15 standards, this O-Ring is easy to install and ensures a precise fit for standardized O-Ring grooves. The material provides excellent resistance to hydrocarbons, oils, greases, and most common fuels, making it a cost-effective solution for sealing when exposed to oils, fats, and vegetable oils. The hardness rating of 71 IRHD guarantees a long service life and dependable sealing under compression, making it ideal for general engineering maintenance and assembly tasks.

Operating temperature range spans from -30°C to 90°C, supporting stable performance in both low and high temperature environments. This O-Ring is widely used in manufacturing, automotive repair, power transmission, fluid handling, and plumbing systems, where prevention of fluid or air leakage is critical to system operation and safety.

Although mainly for static applications, it can also facilitate limited rotary or linear motion seals where design allows. Maintenance teams value its versatility and long shelf-life when the correct conditions are met, offering up to 15 years of service in optimal environments.

To preserve compatibility, avoid exposing this O-Ring to ozone, esters, ketones, aldehydes, chlorinated hydrocarbons, or nitro hydrocarbons. Always select the right material and size based on fluid type and intended application to ensure peak system integrity and reliability.

Common industrial sectors for this part include general manufacturing, automotive, hydraulic and pneumatic equipment, and plant maintenance. EnvMart offers a comprehensive selection of RS PRO O-Rings for industrial and engineering needs - browse the full range for your sealing requirements.
