Air Chuck and Tire Inflator

[bob_the_builder]

I was hoping someone could explain why standard air chucks cannot be added to a tire inflator.

I currently own this Tool Aid tire inflator (which I love by the way) and I would like to add a handle to the end just to make it a little more comfortable to hold.

Why can't an "air chuck" be added to the end of the inflator such as something like the Snap-on GA359B

In the description, it clearly states that it cannot be used on tire inflators. I noticed that some of the milton air fittings also say the same thing.

I am just wanting what is the reasoning.

You're right, they are horrible for airing up say..... a tractor tire. I've thought about making a handle for mine. I thought about getting even one of those that have the small lever for clipping on the stem for hands free.

You can add different air chucks, they just have to be air releasing. If its not air releasing, you cannot force air into the tire from your air hose because of the pressure between the tire, through the chuck and back to the airline is at shop pressure. Essentially you end up dead headed and the inflator doesnt work (Can't read pressure).

Milton and others make optional air releasing (open) chucks.

I use this one from harbor freight. It's got a gauge, pistol grip, and a clip to hold it on the valve stem. Works great.

I was looking at the Milton catalog and as you mentioned some are listed as "open" and others are listed as "closed". For my understanding would a "closed" chuck be like a check valve and it lets air out but not air in? where as a "open" chuck lets air in and out?

I'm guessing because Maybe some inflators like mine have a button to release air pressure if the tire pressure is too high?

The open style have no valve at all. On my milton inflator when you squeeze the trigger air comes out the chuck, even if it isnt connected to a tire. The air stops at the trigger, thats what allows the gauge to take a reading when the trigger is released but the chuck is still hooked up to the tire. Trigger gets released and the line pressure in the line between the tire and the inflator gauge drops from line pressure down to current tire pressure automatically. There might actually be a check valve in the inflator handle as well but Im not sure.

I swaped in a regular style (snap on handled one actually) chuck onto my inflator and it wouldnt work, thats how I figured it out. IIRC the guage on the inflator creeped up to line pressure and wouldnt read tire pressure, I dont really remember 100%??? Up till then I didnt clue into the need for an open chuck.

You can use that Snap-On air inflator handle but you need to use the air inflator (end part) that came with your gauge.

Exactly.

Yep. That handle is just a plastic handle stuck onto a nice 1/4 NPT pipe ******. You can take the closed valve off the end, and stick on an open valve.

This is my current go-to angled open air chuck:

It's not locking though. On my second inflator, I keep a locking straight on open air chuck like this:

but with a handle.

I might get one of these: Freeman FATDTI Digital Tire Inflator . The handle looks comfy and for $13, it's worth a gamble. I might be fun to test it for accuracy too.

Thanks for all the input. I think I will speak with my Snap-on dealer next week to pick up the air chuck. Worst case if it does not work I can always change out the closed fitting to an open one.

The funny thing is I think the SG Tool Aid air chuck comes with a closed fitting. If I do not have the inflator connected to a tire and pull the trigger no air comes out and the gauge measures line pressure.

Anyway, I will see what works once I get the air chuck connected.

Since I've found this site I've spent about 200 bucks on stuff. Now add this to the list.
