Pneumatic fittings are used to connect lengths of tubing, pipes and hose in pressurised pneumatic systems. They typically have tighter seals and lower pressure requirements compared to hydraulic fittings and can be commonly found in robotics within production lines as well as products we use within our daily lives such as vacuums and tyre pressure gauges.
Pneumatic fittings are predominantly made from three different types of material; plastic, stainless steel and polymer. Stainless steel and polymer fittings are used in the food and beverage industry to comply with hygiene regulations, but all three types can be used in any other application.
Pneumatic fittings can work in several different ways and in an array of configurations.
To calculate the required thread size of the pipe fitting, you will need to measure the inner diameter of the threaded hole you would like the fitting to be connected to or the outer diameter of the threaded section of your existing fitting.
