RS PRO Nitrile Rubber (NBR) Black O-Ring 70 mm Inside Diameter 77 mm Outside Diameter 3.5 mm Thickness 71 IRHD 196-5106

RS PRO 196-5106 Nitrile Rubber (NBR) O-Ring is a high-quality black seal with an inside diameter of 70 mm, outside diameter of 77 mm, and thickness of 3.5 mm. Manufactured from nitrile rubber, this O-ring offers excellent durability and resistance to oils, fats, greases, and vegetable oils, making it suitable for hydraulic and pneumatic engineering applications.

This versatile O-ring seal is ideal for pumps, drive belts, and other machinery requiring reliable fluid or air sealing. It operates reliably within a temperature range of -30°C to 90°C and provides a hardness of 71 IRHD to ensure effective sealing performance over its lifespan.

O-rings form a donut-shaped seal that prevents fluid, air, or particles from passing through joints, maintaining pressure, preventing leaks, and protecting mechanical components from contamination or damage.

Applications include industrial manufacturing, automotive repair, hydraulics, pneumatics, and power transmission technology. The material's high chemical resistance supports longevity against most hydrocarbons, oils, and fuels.

Manufactured from nitrile rubber for excellent oil and grease resistance. Operates within temperature range of -30°C to 90°C. Effective hardness rating of 71 IRHD for durability. Designed for use in hydraulic and pneumatic sealing systems.

Provides secure sealing to maintain pressure and prevent leaks. Compatible with pumps, drive belts, and general engineering applications. Assures protection in industrial and manufacturing environments. Available in a wide range of metric and imperial sizes for versatility.

RS PRO products meet rigorous industry standards to ensure high quality and performance. This O-Ring is an essential component for maintaining efficient and safe operation in fluid power and mechanical systems.
