For the 4mm OD, what size are the outer screw and nut?

The corresponding threads of each size are as follows: 4mm Tube OD(M12*1); 6mm Tube OD(M14*1); 8mm Tube OD(M16*1); 10mm Tube OD(M18*1); 12mm Tube OD(M22*1).

Is everything in this safe for use with beverage without imparting any taste?

Maybe not, It's not food grade.

Will the 10mm work with 3/8 OD tubing?

There is little difference between 3/8 "and 10mm. If the working pressure of the airline is not too high, it can generally be used normally. The internal sealing ring can catch the 3/8" tube OD hose. If the pressure is too high, leakage may occur.
