Pneumatic Air Fittings: Interconnectivity and Suitability for Everyday Life

Seeing a factory assembly line, what comes to our mind? We visualize a line of fast hands screwing, turning, inspecting many parts and tinkering which eventually come together to see a finished product. Years ago, the above imagination was true but now in modern times, it is found in fiction. Modern assembly systems and manufacturing systems employ the use of automated systems using pneumatics and air fittings.

We will consider pneumatic air tools for the purpose of this article. We will focus on one of the critical components keeping the performance of pneumatic systems as the way they should: Pneumatic fittings.

Pneumatic fittings are used to connect pieces of tubes, pipes, and hose in pneumatic (pressurized gas) systems. In order to meet industrial quality requirements, they are manufactured with a high degree of precision and quality. The industrial quality requirement includes SEA, ISO, JIS, DIN AND DON standards.

Tighter seals and lower pressure requirements typically characterize pneumatic air fittings. This property makes it responsible for the well-timed direction of compressed air. The choice of the right fitting is essential. There are varieties of pneumatic fittings ranging from various sizes and shapes. The varieties include straight fittings, elbow fittings, cross fittings, valves and more.

As they come in varieties, which is the same way they have various functions, air fittings can be identified by their mode of connection, how they are ‘barbed’, material make-up and style of compression. In the selection of appropriate air fittings the following factors, need to be considered in order to ensure the best performance of the pneumatic fitting. If the choice of pneumatic air fitting does not turn out right for the application, its will lead to reduced efficiency and reduced power thereby minimizing the benefit of delivered in the first instance.
