RS PRO Nitrile Rubber O-Ring, 68 mm ID, 71 mm OD, 1.5 mm Thick, Black, Model 196-5522

The RS PRO 196-5522 Nitrile Rubber O-Ring provides a robust and dependable solution for industrial sealing needs in a wide range of mechanical and fluid power systems. This O-ring is manufactured from Nitrile Rubber (NBR), a material well known for its resilience, cost-effectiveness, and resistance to oils, fuels, and a variety of chemicals commonly encountered in hydraulic and pneumatic applications.

With an inside diameter of 68 mm and an outside diameter of 71 mm, the 196-5522 O-Ring is engineered for precision fitting. The 1.5 mm thickness allows for dependable sealing in compact assemblies, ensuring that fluids and gases remain contained under diverse operating conditions. Its black colour helps with visual identification and compatibility with a wide array of industrial environments.

This O-ring maintains its sealing performance across an operating temperature range from -30°C up to 90°C, accommodating both cold and elevated process environments. It is rated at 71 IRHD hardness, providing the elasticity needed for both dynamic and static sealing applications - including shaft seals, face-to-face seals, rotary, and linear movement assemblies.

RS PRO Nitrile O-Rings such as this model are commonly applied as seals in pumps, drive belts, and a variety of general engineering and maintenance tasks where oil resistance and sealing integrity are important. The NBR material provides a long service life and retains flexibility and effectiveness even when exposed to fats, greases, most hydrocarbons, and other aggressive fluids.

Typical applications for this O-ring include use in industrial manufacturing, hydraulics, pneumatics, automotive repair, and power transmission technology where dependable and maintenance-free sealing is required. When used within the recommended parameters, NBR O-rings can deliver years of leak-free service and reliable equipment protection.

Note that this type of O-ring is not suitable for applications involving ozone, esters, ketones, aldehydes, chlorinates, or nitro hydrocarbons as these can degrade NBR compound properties.

Versatile for use as shaft, face, or static seal types. Chemical resistant and compatible with oils, greases, and many industrial fluids. Long-lasting material composition for minimized maintenance needs. Reliable sealing in both dynamic and static environments.

Simple, quick installation and replacement, supporting efficient plant maintenance schedules. Widely used in industrial and manufacturing sectors, including plumbing, automotive, and machinery.
