Hey guys, hate to start with a bone headed question, but I just got a 4" Crystal Dragon setup and on the top of the Milk Can B there is an extra hole, I assume it's for a thermometer but honestly have no idea... Any help how to plug it with something useful? Thanks!
Just put a blank cap and tri clamp on it or even a sight glass lense. Good luck
Best fitting is an element adaptor with a 1" ball valve screwed into it. Shove a funnel in the ball valve to fill.

like @MickyMoonshine , I use the glass piece , silicone o-ring, and 2" clamp... you can watch the pre-heat and boil...
Sight glass, fill port, thermometer port, or even a 2" pot still head for stripping runs.
maybe @Lloyd can source funnels with a ferrule on a 10-15 degree offset... or.... wait for it...... Man I shoulda patented this.... oh, well..... two bosses on the side of the funnel base, and a clamp-ferrule combo that can be put on with one hand and variably adjusts the funnel but locks when clamp is tightened with an over-center lever... and maybe a vent tube run up the outside of the funnel and over the lip back into the funnel ...goodbye million dollar idea, fly, be free!
We should have included that on your invoice. Sorry that we did not remind you. it needs a 1.5 end cap, 1.5 silicone gasket, and a 1.5 clamp.
You can also add another plate in the bottom flange by swapping the flange gasket with a Crystal Dragon gasket. Looks like your threaded rods are plenty long enough.

Thanks @Smaug, will I need to plug it with anything during the run then? Genuinely my first go at this sorry!
Thanks everyone! Hopefully my first go will redeem myself :)
^^^ what @captainshooch said....
Yes you do need to ensure that any holes in the boiler are sealed during the run. Otherwise the vapour will shoot out that way.
If you are in the states, and in a pinch to run, you can pick up a triclamp cap, gasket, and clamp at your local grainger. You'll pay top dollar though.
