RS PRO Nitrile Rubber (NBR) O-Ring 1.6 mm Inside Diameter, 3.6 mm Outside Diameter 196-5381

RS PRO 196-5381 Nitrile Rubber (NBR) O-Ring is specifically engineered for sealing applications that demand reliability and durability in hydraulic and pneumatic industries. The O-ring’s 1.6 mm inside diameter and 3.6 mm outside diameter, combined with 1 mm thickness, make it suitable for precise sealing tasks where fluid or air leakage prevention is critical.

Crafted from high-quality nitrile rubber, this O-ring withstands exposure to fats, greases, vegetable oils, and a wide array of hydrocarbons, oils, and fuels without degradation. Its hardness of 71 IRHD balances elasticity and wear resistance, promoting a long-lasting seal life under mechanical stresses.

Operating effectively between -30°C and 90°C, this O-ring is versatile for use across various industrial, manufacturing, and automotive applications. It can be deployed as shaft seals, face seals, or in setups requiring rotational and linear movement with minimal friction and leakage.

The black coloration adds to its compatibility with numerous systems without aesthetic or chemical interference. The O-ring's durable composition ensures consistent operation, helping maintain system pressure, prevent contamination, and reduce maintenance downtime.

Typical use cases include pumps, drive belts, fluid sealing in hydraulic and pneumatic systems, plumbing seals, automotive repair, manufacturing process machinery, and power transmission technology. With proper material selection aligned to the operating environment, NBR O-rings like this one can last up to 15 years under normal conditions.

Manufactured from durable nitrile rubber (NBR) material resistant to fats, greases, and vegetable oils. Ideal sealing solution for pumps, drive belts, and hydraulic and pneumatic engineering applications.
