Product Description
The RS PRO 196-4941 Nitrile Rubber (NBR) O-Ring is a robust sealing solution designed for critical fluid or air containment in a range of industrial and commercial applications. With a 170 mm inside diameter, 174 mm outside diameter, and a 2 mm thickness, it offers precision fit and reliability.
Manufactured from high-performance nitrile rubber, this O-ring is specifically engineered for resistance to oils, hydrocarbons, fats, greases, and vegetable oils. It is ideal for use in hydraulic, pneumatic, automotive, plumbing, and power transmission systems. The O-ring's formulation combines cost-effectiveness with chemical durability, extending its operational life while maintaining optimum sealing capacity.
With a hardness rating of 71 IRHD, the O-ring ensures both flexibility and strength, accommodating rotary and linear movements without compromising the quality of the seal. The operational temperature range spans from -30°C to 90°C, making it suitable for demanding environments where thermal stability is essential.
Applications include sealing pumps, drive shafts, plumbing joints, hydraulic pistons, and industrial machinery. When compressed between two mating surfaces, the O-ring creates a secure, leak-proof barrier, maintaining system pressure and keeping contaminants out. The black color enhances compatibility with standard O-ring housings and simplifies identification during maintenance.
This O-ring is suitable for use in a wide range of metric and imperial sizes and offers superior performance versus traditional sealing materials in its class. However, the nitrile rubber composition should not be placed in environments containing ozone, esters, ketones, aldehydes, chlorinates, or nitro hydrocarbons.
The RS PRO 196-4941 O-Ring is rigorously tested for quality and conforms to strict industrial standards, delivering proven reliability in manufacturing, laboratory, plumbing, automotive, and power transmission scenarios. It is trusted globally by engineers for its dependable sealing capabilities, easy installation, and maintenance-friendly design.
