RS PRO Nitrile Rubber (NBR) O-Ring Seal 50 mm Inside Diameter 56 mm Outside Diameter 3 mm Thickness 71 IRHD Hardness 196-5058

RS PRO 196-5058 is a high-quality Nitrile Rubber (NBR) O-Ring Seal designed for reliable sealing applications in industrial, manufacturing, hydraulic, pneumatic, automotive, and plumbing sectors. This O-ring features a 50 mm inside diameter and 56 mm outside diameter, made from 3 mm thick black nitrile rubber with a hardness rating of 71 IRHD, ensuring durability and excellent resistance to chemicals, oils, fuels, and greases.

The operating temperature range from -30°C to 90°C makes it suitable for a variety of environments where consistent sealing performance is critical. The nitrile material is particularly resistant to fats, greases, vegetable oils, and various hydrocarbons, making this O-ring a cost-effective choice for pumps, drive belts, and general engineering applications within hydraulic and pneumatic systems.

An O-ring works by providing a secure sealing fit between two surfaces, preventing fluid and air leakage while maintaining pressure and protecting mechanical components from contamination and wear. The RS PRO 196-5058 O-ring is manufactured to metric standards and optimised for use in both rotary and static seals.

Note that this O-ring is not compatible with ozone, esters, retones, or aldehydes.

Applications include industrial manufacturing, automotive repair and maintenance, plumbing systems, power transmission technology, and fluid power tools. Its versatile design and durable material ensure excellent service life up to 15 years when used under recommended conditions.

The O-ring has a 50 mm inside diameter and 56 mm outside diameter. Constructed from black Nitrile Rubber with 3 mm thickness for robust sealing. Operates reliably over a temperature range of -30°C to 90°C. Hardness of 71 IRHD balances flexibility and durability.

Resistant to oils, greases, fuels, and hydrocarbons. Ideal for hydraulic and pneumatic sealing applications. Not compatible with ozone and some specific chemicals. Designed for use in pumps, drive belts, and general mechanical sealing.

Metric sizing ensures standardised fit for engineering uses. Provides long-lasting, cost-efficient sealing performance. Explore more high-quality sealing solutions in the Industrial Supplies > Rubber & Rubber Products > O-Ring Seal category at EnvMart.
