RS PRO Nitrile Rubber (NBR) O-Ring 21 mm Inside Diameter, 25 mm Outside Diameter, 2 mm Thickness 196-4881

RS PRO 196-4881 Nitrile Rubber (NBR) O-Ring features a 21 mm inside diameter, 25 mm outside diameter, and a 2 mm thickness designed to deliver durable sealing performance. Made from cost-effective and robust nitrile rubber, it is ideal for hydraulic and pneumatic applications.

This O-ring is suitable for pump seals, drive belts, and other engineering applications requiring effective sealing against fluids and air. It withstands operating temperatures ranging from -30°C to 90°C and provides excellent resistance against fats, greases, vegetable oils, hydrocarbons, oils, and fuels, ensuring long-lasting reliability.

The black O-ring offers good chemical resistance to most hydrocarbons and fuels, making it suitable for a wide variety of industrial uses requiring secure, tight sealing to prevent leaks.

Its versatility allows use as shaft seals, face-to-face seals, and enables rotary and linear movements within machinery components. However, it is not compatible with ozone, esters, retenes, or aldehydes.

Applications include industrial manufacturing processes, plumbing systems, hydraulic and pneumatic equipment, automotive manufacturing and repairs, and power transmission technologies.
