Just wanted to pass along my results sourcing parts and pieces for my builds. Many of the suggestions on this forum are out of date. These are current as of this week. These are US sources but they may ship out of country. I don't know, you would have to ask.
CSST. It was a problem finding ready to use (no coatings) csst. Here is a good place, every size and every fitting:
https://www.plumbingsupply.com/gasconnectors.html
Copper fittings: https://www.supplyhouse.com/
Supply house has very reasonable shipping for small orders. Over 99 bucks is free. Not hard to do if you're building a still or two.
boiler fittings: https://www.brewhardware.com/
All of these sources are friendly and will answer questions.
It was cheaper for me to purchase all my copper pipe from local plumbing supply houses. If I can find what I need in Montana USA I'll bet anyone in this country can find it too.
I bought all my ferrules, ptfe gaskets and clamps from Amazon. If you buy type M pipe all the 2" ferrules will fit inside perfectly.
