For tire service I use these. I do NOT have any wheel covers, just bare steel wheels and a plastic hubcap on the front that doesn't interfere. Its a truck, I don't want fancy wheel covers to make checking tires and lugs more difficult. I tried the long valve stems (Borg) and on mine, they didn't fit, and I realized it was Bit** to remove and install the rear tires without damaging the stems, and made the wheels non-interchangable. They may work for some, but I am a hubcap type of guy.
Foot long Milton chuck p/n S-693-12. Straight on the end, back angle also. Only dislike is that it has grooves inside the ends to "lock on" the threads on the stems. More difficult to push on and off in a restricted place. You can replace them with non groove screw in ends from Milton, p/n P500-2

To make checking air pressure easier, throw away the caps and buy these [/url]https://www.amazon.com/Alligator-V2B-Inflate-Through-Valve/dp/B014VCY3S2/ref=sr_1_1?s=automotive&ie=UTF8&qid=1512611409&sr=1-1&keywords=alligator+tire+caps[/url] These are inflate thru the cap type, brass, made in Germany. Keeps dirt out, easy to check pressure and air tires up. They have grooves (not threads) on them to allow the locking chucks to bite on, and this is the reason I want the smooth bore end caps on the chucks.

For a gauge, anything long with a chuck like the air chuck,

I really do not like the inflator/gauge devices. They have been around for years, but are stupid expensive and if they break, get out of calibration, etc, its a lot of money lost.
