Buna rubber gasket
The very first thing that you should know about our Buna rubber gasket is that it is a commonly used material, famous for its incredible strength and durability, as well as oil, chemical, and liquid resistance. It perfectly combines resistance with low compression sets, and since it is also highly resistant to wear and tear, abrasions, and vibrations, it’s one of the most used elastomers on the market – one that is also quite affordable. Buna is also commonly called Buna-N or Nitrile rubber, and it shows that it has exceptional resistance to almost all fuels and petroleum oils, however, it will not be impacted by alcohol, greases, hydraulic fluid, as well as water.
There are other properties of our Buna rubber gasket, including the ability to withstand wear and tear, different weather conditions – including high and low temperatures – solvents, grime, dust, humidity, the ozone, as well as UV rays. Depending on the composition of the Buna rubber gasket, its physical and chemical characteristics could easily vary. When the Nitrile amount is higher than some other options, the Buna rubber gasket will be incredibly durable, flexible, and it’ll provide higher resistance to all of the aforementioned substances.
When compared to some other options available on the market, the Buna rubber gasket we offer in our E-commerce store will provide better strength and it is more resistant to substances than, for example, natural rubber is. However, you should know, its flexibility will also be limited by the composition, which is why our clients need to ensure that they choose the shore grade properly. It’s also worth mentioning that our Buna rubber gasket is capable of withstanding the sun and it is flame-resistant, hence, even when used in environments that are extremely hot, the Buna rubber gasket will not change its shape, size, or characteristics.
