Product Description
RS PRO 196-4891 Nitrile Rubber (NBR) O-Ring offers reliable and versatile sealing in various industrial and engineering environments. Constructed from high-quality NBR material, the O-ring delivers exceptional resistance to oils, fuels, hydrocarbons, fats and greases, ensuring minimal degradation and maintaining a secure seal across demanding applications. Its precise dimensions of 30mm inside diameter, 34mm outside diameter and 2mm thickness make it suitable for use in both hydraulic and pneumatic systems, as well as in pumps and drive belts.
This O-ring is engineered to withstand operating temperatures from -30°C up to 90°C, which enables deployment in environments subject to fluctuating thermal conditions. Rated at 71 IRHD hardness, the O-ring provides optimal balance between flexibility and strength, extending its service life and sustaining pressure integrity throughout cycles of rotary and linear motion.
The black colour and metric sizing streamline compatibility with standard industrial components, making installation straightforward and ensuring a precise fit. The O-ring’s versatility allows it to function effectively as shaft seals, face-to-face seals, or in dynamic applications where fluid, particle or vapour leakage must be prevented.
Typical use cases include industrial manufacturing, automotive repair, plumbing, hydraulics and pneumatic systems, and power transmission technology. Its durable construction and resistance to most hydrocarbons, vegetable oils and chemicals dramatically increase service life while maintaining system integrity and safety.
RS PRO O-rings are rigorously tested for quality and performance, meeting demanding industry standards. Note: These nitrile O-rings are not compatible with ozone, esters, ketones, aldehydes, chlorinates, or nitro hydrocarbons.
This O-ring is commonly applied in industrial and laboratory installations, manufacturing facilities, automotive systems, water treatment plants and HVAC applications, providing reliable long-term protection against leaks and contaminant ingress.
