NBR O-Rings for Sealing Applications
Reichelt Chemietechnik (RCT) is a specialist laboratory supplier whose online shop carries an extensive range of high-quality sealing technology, including O-rings made of NBR (acrylonitrile butadiene rubber, Perbunan®). These ring-shaped sealing elements lend themselves to a wide variety of applications. They can be used for everyday sealing tasks – on leaking pipes, for example – but they also perform reliably in the laboratory and across many industrial sectors. Order NBR O-rings from RCT and you can choose from a range of diameters and packaging units; both imperial and metric sealing rings are available.
Key Properties
NBR sealing rings are peroxide-cross-linked and sulphur-free. They also satisfy the requirements for use in the food sector: they are BfR- and FDA-compliant and conform to the European Pharmacopoeia. In addition, these O-rings are suitable for drinking water applications and accordingly meet DVGW requirements as well as the KTW guidelines.
The NBR O-ring seals have a Shore A hardness of 70° in accordance with DIN 53505 and are suitable for operating temperatures from -30 °C to +100 °C. They are resistant to fuels, mineral oils, animal and vegetable oils, aliphatic hydrocarbons and silicones, as well as to dilute acids and alkalis. In aromatic and chlorinated hydrocarbons, however, NBR tends to swell, and it is not resistant to oxidising acids such as nitric acid or peracetic acid.
A key advantage of O-rings with this Shore A hardness over other seal designs is that the ring is compact, self-acting and double-acting.
Applications for NBR O-Rings
The possible uses are remarkably diverse. These ring seals are employed, for instance, in process engineering within the pharmaceutical and food industries, as well as in the chemical industry and in chemical materials and process engineering. Vessel and container construction likewise benefits from these sealing elements – for example in the manufacture of IBC containers.
Last but not least, NBR O-rings are needed to seal static machine components against liquid and gaseous media in process environments, giving them an important role in mechanical engineering as well.
Order high-quality NBR O-Rings at rct-online.de
Seals are fundamental components in both industrial settings and the laboratory, preventing liquid or gaseous media from escaping. That is why RCT's online shop offers a comprehensive selection of sealing elements, including these practical NBR O-rings. We keep many products permanently in stock at our Heidelberg site to guarantee short delivery times. Our resistance list makes it easy to look up the technical data you need to check whether these sealing rings are suitable and sufficiently resistant for your application. If you would like detailed advice, simply call us or send us an email – we are always glad to help with any questions about your order or the chemical resistance of your chosen product.
