Buna-N rubber tubing
Buna-N rubber tubing is the best for the fuel and oil industry, due to its characteristics. Buna-N, which is actually nitrile rubber, and alongside name Buna-N it is also known as acrylonitrile butadiene rubber and NBR. It is a special type of synthetic rubber, which is petrol-based and in addition to tubing, is also used for seals and other similar products.
It is one of the most versatile types of rubber, because due to its characteristics it can be used equally for fuel systems, as well as for car engines, but also for a completely different purpose such as water and other fluid lines, coolant lines and many other different types of lines for transferring fluids and gases.
Buna-N rubber tubing is immensely durable. It is resistant to hydraulic fluids, butane, petroleum, hydrocarbon jet fuels, solvetns, synthetic oils, alcohol and many other substances, making Buna-R rubber tubing one of the most resistant tubing available on the market.
But great resistance to various chemicals is not only what makes Buna-N rubber tubing so durable, but it also has other characteristics that make it both durable and versatile. Buna-N rubber tubing withstands temperature changes of almost 300 degrees Celsius, and also has high tensile strength. When we talk about Shore A hardness rating, the rating goes up to 90. Shore A hardness rating can be around 40, so you will find a hardness rating according to your needs. You can also ask the manufacturer to make the hardness rating according to your needs. The same goes for size and color. Inside and outside diameter as well as wall thickness are subject to customization, according to your requirements. Due to the industries in which it is used, Buna-N rubber tubing usually does not have thin walls, but if your requirements are such, it can be made.
