What is the difference between open and closed dual head "air chucks" (the tools you plug into air compressor hoses to inflate truck tires)? I insist I want to get one from one of the big name tool companies like Snap-On, Mac, Matco, SK, ect. Because the ones in the autopart stores really are bad. It's confusing because the different "air chucks" designated as open and closed look the same???

Closed chucks have built-in shut off valve, and are intended for live air lines.
Open chucks are for valved air lines (tire installation machines/inflation gauges, etc).

I need to find a reasonable priced open chuck for my HF compressor.

It is a piston style compressor with no tank. So I have to screw this thing onto the tire, then turn the compressor on, then connect it to the compressor.

Would work much better (easier) if I had an open chuck that I could just connect to the valve after turning on the compressor.

So I would want an open one if I had a separate hand held gauge and kept alternating between the two until I knew I had the right pressure?

You only need a open chuck when inflating a tire without a valve core. For just airing up tires you need a clip-on chuck, But I would for sure use a pressure regulator. It would be all to easy to get distracted, blow up a tire to 100 psi. That is why I think clip on chucks should never be used with a air tank either. To the OP, I am not for sure what you are trying to do?

Basically I'm a CDL driver\sanitation worker that carries a bag with a dual end tire gauge (among other things) and routinely stops in a garage where there's an air compressor to fill tires that are not up to pressure. Unfortunately I don't have the experience of a mechanic or a tire maintainance specialist.

^^This^^

To clarify:

A closed chuck dispenses air at the moment it is pushed onto the valve stem, automatic operation if you will.

An open chuck is connected to a device which has a valve actuated by a button, trigger or pedal. You would push the chuck onto the valve stem then momentarily turn on the air with one of the above mentioned valves.

Then I'm wrong, I would need the closed chuck which would start inflating into the stem as soon as it's pushed in the stem and then stop when it's pulled off. And the open chucks are like the coin operated machines you see at gas station that have those levers on them and only dispense the air when you squeeze the lever?

no. thats still closed. because nothing comes out if you squeeze the lever unless its on the tire valve.

pretty much all normal ones are closed except special service ones.

Is there anything wrong with a Milton brand air chuck? The Miltons I've bought have worked well. They're widely available and better priced than the ones sold from the tool trucks.

The dual-head air chuck is for reaching in to the inner rear valve stem on dual rear wheels. Is there such a thing as an open dual-head? (I don't think so--the other half of the head would blow air.)
