NBR O-Rings - 70 Shore A

On this page, you can find all the NBR 70 O-rings that we have as standard in our assortment. An NBR O-ring is primarily used for applications involving oils, greases, and fuels. This is because an NBR rubber o-ring has very good resistance to these substances. However, the NBR rubber material is not recommended for applications involving UV radiation or biological oils, greases, and fuels. For more information about our NBR O-rings - 70 Shore, click here:

Understanding NBR O-rings - 70 Shore A

What is the NBR 70 material?

NBR 70 o-rings, also known under the name Nitrile O-rings, are made of a synthetic compound widely used in industrial settings. NBR o-ring is made from acrylonitrile and butadiene, providing resistance to oils, greases, and fuels. The NBR rubber material is a common grade used in sealing applications such as O-rings and gaskets, crucial for petroleum-based fluids. The molecular structure of NBR rubber o-rings prevents swelling and degradation when in contact with oils and fuels. An nitrile O-ring has a wide temperature range of -30°C to +120°C (-22°F to 275°F), suitable for varying environments. However, NBR o-rings are not recommended for UV radiation or certain biologically derived oils and fuels. In short, the NBR rubber material offers reliable sealing where resistance to oils, greases, and fuels is vital.

Why Choose NBR 70 Shore A O-Rings?

NBR O-rings - 70 Shore are a top choice for sealing applications due to their exceptional qualities. Crafted from nitrile rubber, nitrile o-rings offer outstanding resistance to oils, greases, and fuels, ensuring reliable sealing performance even in harsh industrial environments. With a 70 Shore  hardness rating of 70, an NBR 70 O-ring strikes a perfect balance between flexibility and durability, providing a tight and leak-free seal over time. Also, an nitrile rubber o-ring boast a wide operating temperature range of -30°C to +120°C (-22°F to 275°F), making them suitable for diverse conditions. Additionally, the widespread availability of these NBR gaskets as standard components ensures quick procurement and seamless integration into production processes, saving time and resources.
