You need to get 50 posts to get and send e-mail. Go to chat forums, or "what are you watching right now". Would be glad to help, and see you do it safe, and right!!
Best source of info is skunkpharm!!!
Read some of this, to get respect for Butane, although I am relatively sure there were no closed loop disasters, but can confirm.

Hey everyone,
I'm getting parts together for a system like this. Already have a lot of them, my question is about getting a lid with several ports in it so I put a gauge, and possibly put in a sight glass like pictured here on one of the best value vacs systems: http://instagram.com/p/xk5XrDgp4f/?modal=true
Can a lid like that be purchased through glacier (couldn't find it if so) or is this something I'd need to do myself?

^^^Ahhh the special lids and spools section. A whole new world! Lol, thank you...
I think this thread should be stickied. Especially for the parts list on the first page. Plus all the info in the rest of the thread is very helpful. A closed loop system is in my near future and the time op spent putting together that list, and then putting it up for discussion to follow....deserves permanent respect!!
I hear ya...I need more posts...
In the meantime, I hope we can continue the conversation here.
Yeah, I've been there a min...always finding something new...
I've got some questions about some things I'm still unclear about from over there...more on that later...
ugly shit.
Until I get my lil' unit running, my tubes will have to suffice...
=======================================
Hey BrainChild
You can buy the lids from BVV about their pre-fabbed lids...but they're not cheap...
I forget exactly what I was quoted...(defense mechanism...)
How do I pressurize my Lil Terp?
I’m hoping someone can tell me what fitting, or adapter, do I need
to be able use a typical “tire inflator” style air-compressor
on this access valve.
-------------------
From The Generic Terpinator Owners Manual:
6.0 Pressure test the Terpenator assembly at 100 psi, by installing a 1/2" male NPT pipe plug in the Pressure relief valve discharge port and closing all the valves except the dump valve at the bottom of the column.
Install an airline adaptor to the system. We do so by installing a 3/8" 1/4" NPT bushing in the butane injection port, and inserting a 1/4" MNPT X airline quick disconnect.
Bring system up to 100 psi test pressure, by opening the butane injection valve until the compound pressure gauge reads 100.
Close valve and watch to see if gauge is stable or if it registered an ongoing pressure drop.

Am I looking at the right parts?

2x1.5 connector

$15 bucks....
two of those and two clamps and you are at the size you want...
I need to buy and injection T and I also want 2"
To pressure test, inject a can of butane into the top of of your system there. You have ball valves so no problem shooting the tane all way to the bottom.
Close top ball valve, attach pressure gauge to top ball valve, open top ball vale so you can read the increasing pressure...
watch pressure gauge, until pressure maximizes.... The system should pressurize and hold the correct pressure for the temp....
No need to buy anything, no funny looks here....

We made an adapter for testing, by using this fitting and attaching it to a Female NPT X 1/4" male flare. That allow us to use a refrigeration hose to connect them to the male flare on the Lil Terp.

Thanks Hydrosun.
At first, I was like…
But now I’m like...
I know where to find GW’s “Temp/Pressure Chart”
Am I right, that’s what you are talking about?
I just started shopping for a gauge…
(Thought I might not need one)
Any tips on what to look for?
--------------------
Thanks for taking the time Gray Wolf
This is the what I am trying to do.
(But I'm feeling bogged down & Hydrosun is tempting me w/ a new idea...)
The Quick Connect w/ ¼” male thread is a relatively easy find.
It’s the other part that Im having trouble finding.
I can find something that looks close.
But it doesn’t fit the flare…
What size is the flare?
I know / used to know that the flare fitting itself is ¼”
But the flare is a little smaller…
The refrigeration hose fits, of course...but I havent found anything else to fit yet...
Am I looking at this right?
I picked up a liquid filled compound gauge from RSD just the other day. I like the 3.25" dial, but 2.5" works as well.
The pressure and temp chart is just an appx, because the can of tane will come with an accelorant to get it out of the can.... SO the pressure should be higher at any given temp.
What we are really looking for is the system reaches Max pressure, and then holds steady. If the pressure drops then we have a leak...
You are starring at 1/4" compression thread fittings which fit easily with JIC threading (at the 1/4 size), however the compression males are a little shorter than the JIC females and a solid connection is RARELY made.
stainlesssteelfittings.com for the correct parts.

Whatever the gauge stops increasing to. Since we have no idea what the TRUE gas is we can't know its true max pressure, until we observe it in a closed system.
Lets say the mix raises to 120PSI at ambient temp, it should stay at 120PSI forever so long as the temp stays the same. If the gauge drops slowly back down then we have a leak.

Planning on putting together a Lil Terp myself soon. It'll be passive until I upgrade it to essentially a MKIII. I was curious, can I assemble a passive system through glacier tanks or can I run the DIY MKIII out of the box like that?
