FAQS

What is the use of air compressor fittings?

Air compressor fittings are used to connect lines and compatible tools to the air compressor.

What are the different types of fittings?

There are four main types of air fittings:

  • Industrial
  • V-type
  • Automotive
  • ARO

The difference between these fittings is the size of their opening. They are also not compatible with each other unless you employ the use of a universal coupler.

What is the importance of color coding?

Color coding helps differentiate between different types of fittings, i.e., industrial, ARO, Automotive, or V-style. For example, ColorConnex from Legacy has the following color code:

  • Industrial (Type D) – red
  • Automotive (Type C) – blue
  • ARO (Type B) – green

What’s the difference between a manual and an automatic coupler?

With a manual coupler, you have to pull back the sleeve to insert the plug while with an automatic coupler, you push the plug in and the coupler automatically connects. When there is no plug, the automatic coupler’s sleeve is pulled back unlike with the manual coupler’s sleeve.
