What parts are pneumatic fittings and equipment connected to?

Pneumatic equipment can be connected to a wide group of devices and ducts. Especially the hoses and pipes that are connected to the air in different parts of the system. Which pneumatic connections and equipment is the best option for your user also depends a lot on the amount of pressure in the operations that will be performed.
But the important point is to pay attention to the ducts that hold compressed air on both sides of the connections when choosing pneumatic fittings and equipment. Then, according to the amount of pressure in this area, you will choose the best option. These components include things like the following:


If a tube is used in the pneumatic system. It indicates the presence of substances that are closer to the solid state. They are a better option for permanent and long-term installations. Pipe connections in pneumatic equipment are generally fixed more firmly than other types. However, sometimes they are designed and used for frequent separations. Pipes are made and bought and sold according to their diameter.


The use of hose in pneumatic systems indicates the presence of flexible ducts. Hoses are made of one or more layers of plastic material. The possibility of tear and wear in the hoses is high, and for this reason they should be replaced at regular intervals. For this reason, hoses are used in connections and pneumatic equipment that are not permanent and can be easily separated after a while.
