Closed Column DIY?

I broke my open column extractor and would like to go closed Column.

What are my best options out there?

I see Ablaze has decent prices.

I normally run 3-4ozs of trim at a time then vacuum purge...

Seems a person should be able to order that parts cheaper and assemble if he knew where to look.

That's exactly what I did.
At this point I am going to use a cooler and dry ice to drop temps but I am still trying to find a dewaxing sleeve for 1.5" triclamps.

2 questions;

Can I use brass also does it have to be stainless fittings?

And couldn't a person just use a PVC jacket to make the sleeve? Doesn't contact the butane anyway.

Just a thought.
