Comparison of size. I have a 353 and 346 here but they are in pieces :bang: so a 350 was in their place.

I have the adapter but the o ring blows out the side at 140ish. Needs a retaining groove.
 
I've had a 10mm adapter for a couple decades now. Bikes have been using 10mm plugs since back in the day. More room for valves. ;)
 
I haven't had any issues with mine, thought everybody had one :D

Silly Hondas and a couple others have had 10mm for a while, just so happens I can use the one I had on these. I do prefer the proper adapter for the pressure/vac testing though, that's more important than a comp gauge IMO.
