What are the different sizes of air compressor fittings?

Air hoses are measured by their internal diameter (ID), and come in standard sizes of ¼”, ⅜” or ½” or metric sizes of 6mm, 8mm, or 10mm. Since higher ID correlates to higher air capacity, selecting your ideal air hose diameter requires an understanding of the CFM needs of your air tools.

What is the standard air compressor fitting size?

Most standard air compressors require a plug with a 1/2-inch or 1/4-inch flow size, with the latter being more common. Just like couplers, plugs come in automotive, industrial, ARO and V-style designs.

What are the two types of air couplings?

There are two main types of air compressor couplers : Automotive and Industrial. The chart below shows how to identify which connector style you have. As you can see, Industrial style couplers have two striped going across the fitting, whereas the automotive style only has one.

What does NPT stand for in air compressors?

In the U.S. or Canada, the pressure gauge will most likely come with an NPT (National Pipe Tapered) connection.

Is PCL XF same as euro?

Commonly referred to as Euro, the XF-Euro series boasts excellent flow characteristics, providing the workshop with increased airflow when required, giving enhanced tool efficiency.

What are the different types of compressor fittings?

There are several different types of compressor fittings in both National Pipe Taper (NPT) and metric sizes. There are also different styles of compressor fittings from straight and tee to elbow types.

What are air line fittings?

Air-line fitting. This article is a compendium of hand-operable air-line fittings, typically of quick-disconnect type, used for pneumatics and other compressed air purposes including breathable air (a subset of breathing gases ).

What is an AC compressor?
