Tire gauge that doesn't suck?

Q: Does the gauget hold on to the valve?
A: NO

Q: Can inflate and get reading at same time?
A: well, kinda. It does not react like a fuel island meter, where it "rolls" as you pump. You have to let go off the trigger, then the air in the tire will push back to give you an instant readout.

Q: can i replace Chuck on my glad hand hose and save time?
A: no. You get a hose with the "other hand" to create a connection. Similar to your trailer receptacle. And that hose gets connected to the gauge using the usual connectors.

 

If you want to real fancy, you can tap into an existing airtank and add this. So all you do is hook up an air line to either tractor tank or trailer tank using these quick connects

 

This is the one I always carried under my bunk with gladhand adapter.

I did that. After scalping myself a couple times i went back to the glad hand connection.

 

I've got a Mac tire gauge and inflator in one unit. It's survived 3 years in my service truck so far and it still works fine.
