Pneumatic fittings are ideally connectors; they provide the link between various pneumatic system components, including hoses, tubes, and pipes.
They tend to resemble hydraulic fittings, but they are defined by tighter seals. They are also characterised by lower pressure requirements. In addition, they are available in multiple connector types and help to control or stop air flow pressure.
These components are often available in various sizes and can be configured to match multiple tubing and connector requirements. Being able to identify and distinguish the different types of vessels connected to the system is important because it could help to determine the type of fittings considered to be appropriate.
