As many of you are probably familiar, a pneumatic system is any system that relies on pressurized air or gas. In order to drive actions, air or gas typically travels through a series of pipes, hoses, and/or tubes similar to the flow of liquids through hydraulic systems. Connecting to one another and various components in the system, these network channels require airtight seals to maintain leak-free joints. As such, a pneumatic fitting works to establish a tight connection between the components of a pneumatic system. With applications in virtually all industries, pneumatic systems range in their specific channel types, so a vast array of pneumatic fittings are available for procurement depending on the characteristics of their applications. For your better knowledge, we will explore some popular types of pneumatic fittings.
