RS PRO Nitrile Rubber (NBR) O-Ring Seal, 5.1 mm ID, 8.3 mm OD, 1.6 mm Thickness, Hardness 71 IRHD 196-5539

RS PRO 196-5539 Nitrile Rubber (NBR) O-Ring seal features a 5.1 mm inside diameter, 8.3 mm outside diameter, and 1.6 mm thickness, designed for reliable sealing solutions in hydraulic and pneumatic systems. Manufactured from cost-effective Nitrile rubber with a hardness rating of 71 IRHD, this O-ring delivers long-lasting chemical and abrasion resistance, ensuring durability in various industrial environments.

The operating temperature range from -30°C to 90°C accommodates diverse working conditions, making it suitable for applications exposed to oils, greases, fats, and vegetable oils. This black O-ring is versatile and used commonly to seal pumps, drive belts, and general engineering equipment that require robust and dependable sealing performance.

O-rings work by creating a tight seal when compressed between two surfaces, preventing fluid or air leakage, protecting equipment, maintaining pressure, and excluding particulates. The RS PRO Nitrile O-Ring is designed for use across industries such as manufacturing, plumbing, hydraulics, pneumatics, automotive, and power transmission technology where sealing integrity is critical.

This Nitrile O-Ring is resistant to most hydrocarbons, oils, and fuels, offering excellent longevity with potential service lives of up to 15 years when used under appropriate conditions. However, it is not compatible with ozone, esters, and retones, which should be avoided to maintain seal integrity.

Constructed from Nitrile Rubber (NBR) material for high chemical resistance. Operates reliably from -30°C to 90°C temperature range. Hardness rating of 71 IRHD enhances durability and sealing efficiency. Black color for industrial applications.

Provides effective seal for pumps, drive belts, hydraulic and pneumatic systems. Compatible with oils, fats, greases, and vegetable oils. Prevents fluid and air leakage ensuring operational safety and performance. Ideal for use in manufacturing, plumbing, automotive, and power transmission.
