What Is Pneumatic and What Is It Used For?

Pneumatics is a type of technology that makes use of pressurized gas as a means to turn that pressure into mechanical motion of some sort. The air, which is the most common type of pressurized gas for pneumatics, is usually dry. However, it may have lubrication in some instances. Pneumatics can be helpful with the absorption of shock, and this happens to be one of the most common usages of these systems. Pneumatic systems feature a number of different parts and pieces, including a wide range of different fittings and adaptors.


What Types of Pneumatic Fittings and Adaptors Exist?

The following are some of the most common fitters and adaptors for pneumatic systems. The fittings and adaptors are the pieces that hook the hoses into the pneumatic systems, and they come in a variety of sizes and styles, as you can see below.
