My Accu-gage EZ Air gauge is no longer making a proper seal with my tire valve and is just releasing the air - no reading. The brass end had come off, but I screwed it back on and there doesn't seem to be anything else I can adjust. Any ideas? Or do I need to pitch it and get a new one? thanks.

 

I'll bet there was an o-ring lost when the end 'came off'

 

hmmm...I'll see if I can replace that or come up with a makeshift alt.
thanks.
