Product Description
RS PRO 196-4916 Nitrile Rubber (NBR) O-Ring is a high-quality sealing element designed for precision applications in fluid power and mechanical assemblies where reliable, long-term leak prevention is essential. Its metric dimensions - 54 mm inner diameter, 58 mm outer diameter, and 2 mm thickness - make it ideal for sealing joints, shafts, and interfaces in pumps, drive belts, cylinders, valves, and like systems.
Manufactured from robust Nitrile Rubber (NBR), this O-ring ensures optimum chemical resistance, particularly for exposure to oils, fuels, greases, and hydrocarbons, supporting performance across a broad temperature range from -30°C to 90°C. The 71 IRHD hardness rating delivers a stable, durable sealing profile for both rotary and linear movement. Its black coloration assures quick visual identification.
RS PRO's metric O-Rings are engineered for industrial applications, including hydraulic and pneumatic systems, automotive repair and manufacturing, plumbing, and power transmission technology. The product prevents fluid, vapor, and particle leakage by seating between two mating surfaces and forming a secure seal when compressed. This design maintains pressure while safeguarding critical components against contaminants.
Key features include cost-effectiveness, versatility in sizing and material, ease of installation, and compatibility with a range of industrial fluids. The O-Ring is not suitable for use with ozone, esters, retone, aldehydes, chlorinates, or nitro hydrocarbons. Longevity may extend up to 15 years when installed under appropriate conditions for NBR materials.
Choose RS PRO's NBR O-Ring for demanding sealing requirements in manufacturing, construction, laboratory, and HVAC scenarios where quality and reliability are paramount. Explore more options in the Gaskets & Seals category or browse other RS PRO sealing products on EnvMart.
