Frequently Asked Questions (FAQs)

1. Are air compressor fittings universal?

Air compressor hoses are universal in their use of connecting the air compressor and tools. While hoses are universal in use, there are other variables to consider when shopping for an air compressor hose. Different applications and different tools may require different styles and types of compressor air hoses.

2. What size fittings do air tools use?

The most common size fitting is ¼ inch. This is true for both ¼ and 3/8 inch air hose. Most 3/8 air hose comes with ¼ inch ends on it, thus most use a ¼ inch air fitting. Another important thing to consider when choosing the right size fitting is what size of thread is your air tool or air compressor.

3. What fittings do I need for air compressor?

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.
