NBR - Nitrile - O-rings are a popular choice for sealing solutions in a variety of industrial applications due to their excellent resistance to oils, fuels, and hydraulic fluids. They are made from nitrile butadiene rubber (NBR), a synthetic rubber that offers superior chemical and abrasion resistance.
One of the key factors to consider when choosing NBR O-rings is the Shore A hardness rating. NBR O-rings are available in a range of hardness ratings, including 70, 80, and 90 Shore A.
NBR O-rings in 70 Shore A are known for their flexibility and are often used in applications where low levels of stress and compression are expected. They offer good resistance to abrasion and tearing, and can handle temperatures ranging from -40°C to +120°C, making them suitable for use in a wide range of environments.
NBR O-rings in 80 Shore A are more rigid than their 70 Shore A counterparts, making them better suited for use in high-pressure applications such as hydraulic systems and fuel injectors. They offer superior resistance to abrasion and tearing, and can handle temperatures ranging from -40°C to +120°C.
NBR O-rings in 90 Shore A are known for their high level of hardness and rigidity, making them ideal for use in applications where high-pressure sealing is required. They offer superior resistance to compression set and extrusion, and can handle temperatures ranging from -40°C to +120°C.
Regardless of the Shore A hardness rating, NBR O-rings offer a range of benefits that make them an excellent choice for industrial sealing applications. They are resistant to a wide range of fluids, including oils, fuels, and hydraulic fluids, and can withstand exposure to a variety of chemicals and solvents.
Another advantage of NBR O-rings is their ability to maintain their sealing properties over a wide temperature range. They are able to maintain their sealing properties even in extreme temperatures, which makes them an ideal choice for use in both hot and cold environments.
When selecting NBR O-rings for your specific application, it is important to choose the right size and cross-section. These O-rings are available in a range of sizes and can be custom-designed to meet the exact specifications of your application.
Overall, NBR O-rings offer a high level of durability and resistance to fluids and chemicals, making them an excellent choice for a wide range of industrial applications. Whether you need a flexible, medium-hardness, or rigid sealing solution, O-rings in NBR are a reliable and cost-effective option for your sealing needs. So, if you are looking for a reliable sealing solution for your industrial application, consider using NBR O-rings.
