Anyone used these. Think the internal diameter of a standard valve is 7mm. What sort of size are earth mover valves. Would they fit in a standard hole on a tractor wheel rim. Looking for something so I can blow tractor tyres up quicker in the field

I bought an earth mover sized clip on inflator for just that purpose. It does fit but there's not usually enough thread stuck out for it to seal. Now we have a bit of pipe on a quick coupler which wedges over.

So you use an earth mover size inflator on a standard valve.

Was that a question?

if so, the earth mover clip on inflator is the same size as the outside thread of the air/water valve part. A push on version might be better, I'm not sure a screw on one would fit but might if you faced it off so it wasn't so deep.

use an earth mover connector on standard tractor valves just screw out the fist part out and its brillant for seating beads

find this works even if the thread is short

Standard tractor hole is 5/8" or 16mm . E.M valve requires a 13/16" or 20.5mm hole
 
If you use an EM valve then you’ll need to drill the rim hole bigger. Also don’t use a bent valve as the tube on the bend has got a smaller diameter than the straight valves.
