What are the different styles of air fittings?

The most commonly used industry term for air hose fittings is quick disconnect (or sometimes quick connect). You’ll also hear the quick disconnects referred to as male plugs and female couplers. The four common styles are industrial, automotive, ARO, and V-style.

What is the most common air fitting type?

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.

What does ARO stand for in air fittings?

One thick stripe and one thin stripe on body of fitting. Semi-Automatic. Semi-Universal Interchange Profile (ARO, Automotive, Industrial) not applicable. Three thin stripes on body of fitting.

What are the different types of air hoses?

Common materials include two types of plastic – PVC and polyurethane, along with more traditional rubber. You may also encounter neoprene and nylon hoses. Each has advantages and disadvantages, but all will work well for years if properly maintained.

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 is a universal air coupler?

Universal hose couplings, also known as Chicago and air hose couplings, have an identical claw-style head that allows you to connect to another Chicago hose coupling, regardless of the pipe size or barbed hose ID.

What is the standard fitting for an 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.

What is standard air hose size?

The most common inside diameters are 1/4- and 3/8-inch. Many people choose 1/4-inch hose because it’s lighter than the 3/8-inch variety. It’s easier to roll up, carry around and store.

What is standard air compressor fitting?

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 size is standard air line?

The most common inside diameters are 1/4- and 3/8-inch. Many people choose 1/4-inch hose because it’s lighter than the 3/8-inch variety. It’s easier to roll up, carry around and store.

Are air hose 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.

What are pneumatic fittings called?

Pneumatic push-in fittings, also known as push fittings, are the standard on the pneumatic fittings market and are the most widely used. They are characterized by the easy release function for the tube, i.e. by actuating a releasing ring.

How are air fittings measured?

Using a ruler or vernier, measure across the outside diameter of a male or hose tailpiece thread or measure the inside diameter of a female thread.

What size thread are air fittings?

Thread sizes are typically 1/8″, 1/4″, 3/8″, 1/2″ or 3/4″ pipe thread. A fitting that has female pipe threads (FPT) can only mate to something with male pipe threads (MPT) that are of the same pipe thread size. Nominal – the inner diameter size that the compressed air passes through.
