Product Description

RS PRO 196-5090 Nitrile Rubber (NBR) O-Ring is a precision-engineered sealing solution specific to industrial and mechanical systems. This O-ring has an inside diameter of 180 mm and an outside diameter of 186 mm, with a thickness of 3 mm, making it ideal for applications requiring exact fit and reliable performance.

Manufactured from Nitrile Rubber (NBR), the O-ring offers excellent resistance to oils, greases, hydrocarbons and many other chemicals. The material's properties deliver a balance of durability, elasticity and chemical protection, ensuring a long service life even under demanding conditions.

The O-ring is rated to withstand temperatures from -30°C up to 90°C, allowing use in a wide variety of industrial, engineering, and automotive environments. With a hardness of 71 IRHD, it maintains form and functionality across repeated cycles and diverse fluid interactions.

This RS PRO O-ring supports applications such as pumps, drive belts, hydraulics and pneumatics, as well as general manufacturing and repair. The product is designed for shaft seals, face-to-face connections, and facilitates both rotary and linear movement when forming securely compressed seals.

Its metric sizing (180 mm ID, 186 mm OD, 3 mm thickness) ensures compatibility with pumps and machinery following standard design practices. Black in color, the O-ring provides both technical performance and easy identification in maintenance routines.

For reliability and safety, the O-ring prevents passage of particles, vapor, and fluid between joined components, helping to maintain system pressure and ensure operational continuity. The chemical resistance and robust design enable use with most hydrocarbons, oils and fuels, while being unsuitable for ozone, esters, retone, aldehyde, chlorinate and nitro hydrocarbons.

This O-ring is suitable for industrial, manufacturing, automotive, hydraulic, and pneumatic sectors, offering decades-long performance when operated within recommended material conditions.
