I'll chime in:

There are many different configurations out there in the big industrial world of ours. However, there are two major types that are most commonly used.

First and foremost, I am going to say that the "Type 15" is generally the standard in most industrial applications.



The second is the "Automotive" or "T" type (couldn't find an image of one) Made by Wilton.

Now, there are a dozen or so type configurations, like

Type 11
Type 12
Type 14
Type 58

Most of these all have 1/4" to 1/2" NPT inside diameter and CFM or airflow rate indicated which type you may want to use.
In my shop, we use the Type 15 on all airtools and air nozzles under 3/8" NPT.

All pneumatic fittings are generally measured by the inside diameter of the hone supplying the air.

Yeah, that sounds exactly right. The Type 15 is just more common and you get the same amount of airflow as the others.

You're welcome.

Peter,

There are universal female fittings at Lowes by the air tools (they have air fittings in both plumbing and by the tools). That's what I put on my air tank in the truck. So far everything seems to fit.

I 've actually got a passel of both as you can buy them both. Maybe I picked the Automotive because that lip on the front looked more substantial and more metal is better, unless it doesnt' work with anyone else's.
