I have bostitch compressor with 6 gallon tank and regulator so I don't have air pressure supply problem,
but I bought this Dual Head Straight Air Chuck Inflator With Inline Gauge and it seems to be a pain to use? https://www.harborfreight.com/dual-h...uge-63570.html
More often than not; I think I am letting air out of the tires than adding? It is really nerving on trying to fill the backside dual tire (yes I have tire extension). My Merlin chuck does not lock, but I have seen them using this type of chuck and gauge at places like Just Tires; so I just bought one thinking I was going all out (not being cheap).
Anybody know what I may be doing wrong or can recommend the type of chuck and gauge I should use?
On the flip side, my local Just tires will check and fill my air pressure on all of the RV tires for free. But I wish to do when I am home or on the road.
