A Guide to Nitrile O-Rings
December 1, 2023 – by Eastern Seals
Nitrile Butadiene Rubber (NBR), commonly known as Nitrile, is a popular material for O-Rings in various industrial applications. Its balance of cost and performance makes NBR O-Rings a go-to choice for many sectors, including automotive, manufacturing, and oil and gas industries.
Excellent Oil and Fuel Resistance: NBR’s primary advantage is its exceptional resistance to oils and fuels. This includes petrol, diesel, lubricating oils, and other types of hydrocarbons, making NBR O-Rings perfect for applications in fuel systems, gearboxes, and engines.
Good Mechanical Properties: NBR O-Rings offer strong tensile strength and resistance to abrasion, which is crucial for dynamic applications involving movement and vibration. Their durability under mechanical stress ensures a longer service life.
Temperature Range: NBR O-Rings typically function effectively in a temperature range from -30°C to +100°C. This range makes them suitable for many standard applications, though they are not ideal for high-temperature environments.
Versatility in Applications: Due to their resistance to oils and hydrocarbons, NBR O-Rings are widely used in the automotive, aeronautical, and oil industries. They are also found in hydraulic and pneumatic systems, providing reliable seals in various machinery and equipment.
Customization Options: NBR O-Rings are available in a range of hardness and can be formulated to enhance specific properties, such as temperature or chemical resistance. This adaptability allows for tailored solutions in diverse industrial applications.
Limitations: While NBR O-Rings are resistant to many substances, they are not recommended for use with ketones, ozone, esters, aldehydes, chlorinated and nitro hydrocarbons. Understanding these limitations is vital for ensuring the right application.
