Anyone familiar with the proper terminology for NPT fittings for air-hoses? I want to replace some and I want the right style. I don't really like the ones you have to shove the tool into and it automatically locks. I like the ones where you slide back the sleeve to connect as well as disconnect. Does this make any sense to anyone but me?

I just take one of my (male) fitting to my home owned auto supply
place and try it to see which one it fits. My brother changed to the
push in type and likes them. They do have a style number but I can
never remember which is which.

I've had problems with the HF brass fittings. They have **** poor tolerances and
many
of them will not mate with the fittings I have from non-HF sources. I've had no
problems
with the HF silver colored fittings.

Go with Milton brand fittings. I can't say that I have seen one that
was not easier to couple by pulling back the sleeve. One thing to watch
for is one with a guard which prevents the fitting from uncoupling if
you drag it around a corner.

About 2 yrs ago, I complained about my half dozen couplers leaking like hell, purchased from HF, Lowes, Home Depot... all were cheaply priced, appropriate for their quality.

I think it was Leon who recommended Milton couplers, back then. I vote Milton brand.

Echo the Milton fittings. I have some, but not all of mine are Milton. I
don't have any with the guard, but I've never had a fitting uncouple
dragging an airhose around a corner, so I probably wouldn't look for it
myself. I have had the cheaper couplers suddenly uncouple. Imagine spray
painting a car and half way through a coat, the damned hose uncouples for no
explanable reason! I check every coupling when I make it, with a good tug
so it isn't like I don't pay attention to this stuff.

Avoid the universal couplers from Home Depot and Lowes, at all cost! Pure
junk! They will blow off the coupling with no notice, wear out very
quickly, and often give you quite a fight just to make the coupling. For
those who have them and like them, God Bless Ya, but one of those will never
grace my garage again.

I prefer the ones you simply push together, and only pull back on the colar
to uncouple. When you have to change tools a lot, you grow to appreciate
this. I hate to have to pull back the colar to simply couple a connection.
With a good quality coupler, you should be able to simply push together and
go.

Back in the days when I was employed in the R&D department of a
major manufacturer of these devices, they referred to them as
"Quick connect couplings".

They held the patent for the quick connect coupling, but also offered
the ball
lock device to be competitive.

The "Ball lock" was developed as a way to get around the quick connect
coupling patent.

Sounds like you prefer the "Ball lock" style coupling.

Be aware that there are at least 2 different plug profiles, and they
are NOT
interchangeable.

Take the plug style you like with you when you go shopping.

As mentioned, Milton has been around for a long time.

Good luck.

Not dragging the air hose around a corner, dragging the coupling around
a corner. The coupling with a guard simply has a flat washer like
attachment at the opening of the fitting. If yu drag the unguarded
fitting around a corner it can catch on the slide and pull it back, and
uncouple the fitting. The guard, prevents a corner from pushing the
slide back. Normally not a tough item to find just something to be
aware of if you link more than one hose together.

explanable reason! I check every coupling when I make it, with a good tug

Maybe the slide was unguarded. ;~) Sometimes just dragging an
unguarded coupling along the floor will uncouple the fitting.

Not in this particular case. My hose length from the gun to a point about 5
or 6 feet back, never sees the floor while I'm shooting. Contaminates and
all that. It's always either simply suspended by the height of the gun off
the floor (the height of what I'm shooting, or it is held up by my free hand
or draped over my shoulder. My gun gets uncoupled after every coat, before
I put it in the stand, and the hose is draped to keep it off the floor.
That's where good couplers come into play - they have to withstand repeated
use, and make a solid coupling.

Really, I just got rid of the type where you have to pull back the sleeve.


Just make sure you get the Universal style so you can work both type of
connectors.. same price 2 styles.

I have replaced my HF connectors with Home depot connectors cheaper and
they seal better. Don't get me wrong the HF are good units for the
pieces that fit on the tool, but I found that the HD units are what I
needed for a better seal, and cheaper price.

Hey Jeff - I don't know how much you use your stuff, so I can't speak to
your experience. My experience is that I use my air tools a lot - a very
lot. I have come to hate those HD connectors. I'll never buy another one

I just bought them a couple of months ago.

Long ago I had industrial couplers that I got at a machine shop supply.
Could not find it where I live here. Nothing matched.

I switched over the HF units. They were good. But for some reason the
female in my garage always leaked... even replacing them a few times.

I wanted the type that are ready to connect rather than pull the sleeve
back. I bought about 5 to 7 at HD.. so far so good.. I hate the idea of
replacing them again..

My problem is the Milton connector you all talk about doesn't match any
of my male connectors. So I would wind up replacing them all, and that's
a lot of connectors...I have one Milton that I bought long, long ago.

Actually, I bet most home shops have less than that. I'd have to really

Er, no, he's not the only one. I once had the (blonde) wife of a customer

What makes a chicken kosher anyway?"

"It's been circumcised," I replied.

"Oh," she said.

I will look for the type that has the sleeve already retracted until
connected.. but that's a good price.
As the current HD version fails I'll replace with these.

They are not on the line all at once. just have connectors.
At most I use 2-3 at a time. Mostly one at time.
I don't use my Binks touchup, cheap touchup, or large Devilbis sprayer
any longer.

I have gone to the gravity feed since they are nice to work with. No
spitting when you get low. Having more than 2 allows you to load
different colors or dye, topcoat and not have to clean between. Most
everything except catalyzed stuff can survive a few days in a gun, as
long as there is enough in the gun and it will cleanup after use.

I only use it for when I run the compressor long... over and over, I

The regulators are plug and play, meaning that I put them at the tool

I still use my Binks and my Binks 1500 touch up gun for primers. Those

Gravity feed is so much better than suction. Most of my spraying is

I just use one moisture trap in the compressor line (just ahead of the

air tools - I don't bother at the tool end, beyond the trap in the
compressor line.

I keep a regulator on each of my spray guns and a couple of other tools (not
previously mentioned... I have two pnuematic chinking guns which each have a
regulator attached to them). The rest of my air tools do not have
regulators attached to them - no need.

I swear by my needle scaler. I think I paid somewhere around $35 for it at
Harbor Freight and it has performed flawlessly since the day I bought it.
That tool has been put through its paces enough to know that it was a tool
well worth buying at HF.
