Actually not all Silicone is food grade, the stuff that is coloured I would
stay away from, the stuff that is recommended for Aquariums I would and have
used, the stuff marked food grade is the stuff to use.
- Excuse my wanderings, but the elderly have a special dispensation, somewhere.
The mention of "coloured" silicone and inplants just makes me wonder if anyone
has ever seen blue ........, well...... you know what I mean.

- Hi John,
Had the same problem when I built my still, You can get a compression
fitting that will fit 2" pipe from a plumbing supply store (the size
is 54mm here in the uk) Ask for a tank conector in the size you
require but beware the price!!(around £20- you can convert ;)) it
will clamp to the lid with the
compression fitting on the top. You can then slip the column onto
and tighten down (the large!)nut. it only needs to be slightly over
hand tight. you shouldent get any vapor escaping.
Difficult to explaine but easy to see!!
Your sketch would also work but is a bit more fiddly.
Hope this helps
