NBR O rings are made from a type of rubber called Nitrile Butadiene Rubber making them unique. It tremendously helps this rubber to resist oil really good. That is the reason for which most of the people opt to use these NBR O rings in various types of machines. They ensure machines continue to work properly by stopping leaks, and protecting the elements within. O rings but nitrile O rings (NBR) do have excellent resistance to oil and such that are derived from oils. It is extremely beneficial for machinery that uses such fluids. An NBR O ring will help with sealing it up, and as long as a machine has oil inside of it.
NBR O rings: not only they are excellent oil resistant, but also good at heat and chemical resistance. It also allows them to remain strong and not weaken even after they are subjected to very high temperatures. This makes them good for a wide variety of situations, especially where fierce temperatures or chemicals come into play. The most appreciable trait of NBR O rings as contrasted to the others is that their ability to withstand for longer period. They are also tough, made to last for several decades and not wear out easily. This makes them sturdy machine parts, and they can be used over and again without ever breaking or suffering deformation of any sort.
To start, make sure that you note the temperature and pressure in which your machine will be running at. NBR O rings are capable to withstand high pressure and any sort of temperature with minimal deterioration, but that does not mean you can always solve your sealing solution using NBR o rings.
Secondly, Check the size and shape of O ring. NBR O rings are produced in a variety of sizes and shapes, meaning it is crucial that you choose the correct one for your requirements. Using an incorrect size can cause issues, such as leaks.
Lastly, when your NBR O ring is not in use or has been replaced by a new one remember to store the piece in somewhere cool and dry. The way in which the rubber material is stored will significantly aid to lengthen its shelf-life time and stop it from drying or getting brittle.
