I don't have a lot of experience with air tools. When I need to use
one I plug it in and use it. Now that I am looking for a connector or
two that I can't find I see this huge selection and mess.
What is the difference between I/M, U, T, Auto
Why are there different style connectors to begin with? Isn't one
good enough? I take it they are not compatible. Does one deliver
more air flow than another? How do you know which is best for what
purpose?
Please enlighten me - especially if you have a URL with some details
and explanations. Thank you.

Nice question, and I'm interested in the information this will bring out.
The only thing I can say is that getting all the same letter makes it easier
to get all the same kind. I think I have M types, but I still have to take
one with me so I get the right thing because I can't remember if it is the M
or the T or the ??? I have trouble with the slip connectors failing, and
the ball bearings falling out.
Nothing easier than quick connects. I love em.

I don't know the differance, but I have 3 differant style connectors that
from about 3 feet away they all look the same. On was used at a mobile home
builder where my dad worked around 1970, another where I work in a large
factory , and the third is on some air tools my wife bought me for
Christmas. They will not interchange at all., but look almost the same and
are the same size, just will not lock in the other connectors.
It sure looks like they should all lock.

They do have a "universal" female quick connector that accepts the three
common types (industrial interchange, automotive, and the other one whose
name I can never remember). I've been lucky enough to keep all my equipment
industrial interchange, so I've not tried it. :)

Unfortunately, the I/M, U, T, Auto designations appear to be names
given to the various q/d types by either the hardware store or auto
part store industry. They are Type Letters that correspond to the
"real"
As near as I can determine there are a "gazllion" types
the most common (at least in my experience) are
industrial interchange....which appear to be a commercial version of
Mil-Std ones
automotive
ARO
& Lincoln
go the McMaster.com
page 260 they have PICTURES of a bunch of different ones; foreign &
domestic
In aerospace (at least at my company) we used industrial interchange
the next place I worked used "automotive" but they didn't have very
many so I trashed them & standardized on industrial interchange
there is also a hi-flow series that are often used on air tools in
construction
Even though I standardized my personal stuff on industrial
interchange, I keep a couple male & female couplers of the different
types with some pipe couplings so I can rig up a "cross type" adpater
if I'm working with someone who has different q/d's
I suggest to anyone who asks me, that they standardise on industrial
interchange
its messy & confusing...... the Mil-Std electrical connectors or
hydraulic connectors are worse :(
But what I find confusing is that the designations used in industry (&
in McMaster) have been "simplified" by the M, T, U designations in the
hardware store.
Amflo (used to be in Santa Ana,CA) is (was?) a big manufacturer of q/
d's they do not seem to have a website, they have a great paper
catalog (can't find mine)
I think they moved to Arkansas
Here is a link to a comparison page....but "note", the M, T, U
designations are not used!
