Different Types of Air Hose Fittings

Air fittings are an extremely important part of any system that uses compressed air. This is because they help to direct the pipes or hoses through which the air is flowing, while simultaneously delivering air to its users – if need be.

When designing, repairing or overhauling an air system, the different types of air hose fittings can seem overwhelming – but taking a closer look at each type of air fitting and figuring out what their potential uses are, is the first step in choosing the one that’s right for your system.

The most obvious difference between the varying types of air fittings is size. While there are certain standards and configurations of air fittings governed by national regulations, they still come in a multitude of sizes.

Let’s have a look at some of the different types of air hose fittings on the market:

  1. Straight air fittings are the most basic type, accepting air at one end while supplying a device at the other – usually being a tool, valve, air cylinder or other type of air compressor component.
  2. Elbow air fittings makes it possible to connect an airline to its fitting at an angle – allowing for the flow of air to come from the most convenient direction. This device cannot, however, be swivelled continuously. It can only be adjusted once and then needs to be kept in that position while it’s being used.
  3. Rotary union air fittings overcome the limitation of the above, allowing for the continuous movement of the air fitting while in use. It can swivel without wearing out, thanks to movement accomplished by using ball bearings.
  4. Once-touch air fittings are fittings than can provide positive sealing without reducing airflow. They come in a wide range of thread types and shapes, and are named after the technology used in creating their connecting mechanisms
  5. Special air fittings are, as the name suggests, specially designed for use in particularly demanding applications. There are many different types, but for example, one type is designed for use with nylon, soft nylon and polyurethane tubing. Another is designed for copper-free applications, and another is built for high-speed operations with the use of a vacuum or high pressure.
