Jack,
we made some Goodall type valves (Goodall valves are only the ones made by Mr. Goodall) for our steam donkeys.

Should be OK now. A stray blank creeped in...

Jack,
you don't need a taper. A piece of silicone tubing over the filler nozzle acts as a seal.

As I mentioned above, no taper is needed. The plastic tubing collar on the squirt nozzle acts as a seal. Simple and effective.

Jack,
if you make the squirt nozzle e.g. 1/8" OD and the valve opening 5/32" and use a thin tubing it will contract to less than 5/32" if you let it extend over the squirt nozzle, sealing against the chamfer. This was how I used it at first. Then I ran out of the thin tubing and replaced it by the thicker one. Now the seal is made by kind of a longitudinal compression of the tube. This seems to work also. An O-ring may also be an alternative.
