pressurize your system... a better way to find leaks. get it to 125psi and let it sit for a few hours

Lol i know old material makes dark bho- thats why you do the virgin run with spent material to clean it out.
Either you overheated it or ran too many showers.
No reason a gasket or hose is going to make a dark oil.
Had 2 epic runs this morning, set up for the third after lunch.
Couldn't hold a vacuum, had a leak somewhere. Took it all apart,
back together, still leaking. Put my ear to the Appion and could hear
the leak. Damn, figured I fried the seals or something. Took it all apart and
put everything away, all bummed about the Appion and that I was going to
have to rebuild it after only like 5hrs of use. Damn!
As I was putting the last things in the tote, I noticed this little copper washer on top
of the tote! It was the washer from the filter-dryer and it had fallen out after the
second run. I took the filter-dryer off cause it sticks down below the appion a little.
I never even thought those thing could fall out!
What a sense of relief when it all clicked in my head!
First run was 40g second 58g!

ahhh the copper ring of destiny that holds it all together.... even now i see it shining.. deep into the depths of my soul.... learn well what this filter-drying thingy has taught you, brother... for these are the teachings that build what we call life.....
fittings
fittings
So the BHOgarts use parker fittings and some mueller industries. the mueller flare 1/4" flare coupler do not seem to be needing the copper washers, where the Parker ones are. You can easily tell the difference by the parkers have squared off corners and the muellers are rounded. the Parkers also have some P P P labeled on them

Been gone for a while. Now I'm back!
They were using the BHOgart recovery tank at the time which has its valves on the lines instead of on the tank. We did no further testing as we had problems with that tank leaking at the fittings before--so we just switched to a Robinair tank.
By gaskets I meant the rubber(?) grommets that were inside the refrigerant hoses that BHOgart included. I thought I had removed them all but there is a chance I didn't. I do remember that when I took those grommets out they were literally crumbling in my hand. Now that we're on all stainless hoses(and 1 PTFE lined hose) the problem is resolved. We did side-by-side runs by hand and it was a night and day difference.
hashman said:
We don't add heat during recovery. The black stuff came out after 20+ runs but we suspect it was there all along.
I'm not trying to make a point about the hoses or anything like that--just sharing so if someone else has a similar experience they can look at my notes. The entire time I disagreed with the crew about it being the hoses...but people, especially stoners, are stubborn. They claimed, maybe incorrectly, that the "worst hose" was the one from the can tapper to the system.
Changing topics...if you are looking to replace your BHOgart hoses:
http://www.amazon.com/Unisource-Assembly-Stainless-Connection-Pressure/dp/B007ZHZYES/
Those hoses will work if you don't mind PTFE lined(and you shouldn't).
[/FONT]
You would want 48" hoses(qty: 3), 24" hoses(qty: 2), and a 12" hose for the can tapper.
Processhose.com is also a great place to go if you want to get stainless hoses for the BHOgart.
What you want is:
1/4 In T316 SS Annular Corrugated Metal Hose Assembly With T304 SS Single Braid. For the fittings you want:
1 X SAE/JIC Female Swivel, T316 Stainless Steel, 1/4 in
For a side by side shootout, we need a machine that is available, and not currently committed to extraction. The only Mk II that I've ever built, is automated and built into a structure, so not very portable and automated machines are never as fast as a manual one, because everything is timed for worst case scenario.
The other automated Mk II, which I only supported the builder on, is over the hill and far away, besides being in daily production.
Neither belong to me, or Skunk Pharm Research, as I built the one for Specialized Formulations.
I could build a Mk IIA manual version, instead of the Mk IVA, but the Bink's stainless pressure pot is expensive and a long lead item, in addition to not being as advanced in design as even the Mk IIIA, and sorely behind Mk V technology.
Can you think of any good reason for us to compare my oldest technology to BHOgards latest, when the object is to compare nuances? Anyone looking for a knockout punch, is apt to be sorely disappointed, and I don't know about you, but when I compete, I do so to win, even if the prize is a handshake or a beer.
I'm also not building the Mk IVA solely as a race machine, nor is it a hot rod. It fills the gap between the Mk IIIA and the Mk V, and incorporates their better features, besides adding a couple.
The biggest change from the Mk IA & II, is that the Mk IVA uses a 10" X 12" sanitary spool for a tank, instead of the stainless paint pot. That makes it much easier to clean, after being run at ultra low temperatures, and cost about half as much for the tank.
I am also building it as a test sled, and as such it includes sight glasses at key points, as well as a thermocouple with digital readout in the butane pool, so we can start developing ways to monitor cryogenic extractions somehow other than watching unmoving vacuum gauges and what level the ice is forming on the outside of the tank.
This is the prototype for the production Mk IVA series, which I have arranged for others to build henceforth, and if I personally build any more Terpenators, the Mk VI will be next, with banks of columns and multiple collection tanks.
A long answer to a short question, and perhaps the shorter answer is that I am retired and only do this for fun and it is more fun doing it the way I am.

I've had more problems with the inline hose valves leaking at the packing glands than the more robust ball valves that I use on the machines. All of my original hoses had ball valves, and now the only inline ball valve that I use is a short whip that I use when loading canned butane.
Because of the temperatures our extractions are getting down to, we are using PTFE hoses with a stainless over braid.
We still use the 1/4" vacuum pump line and the line from the tank, but upgraded to 1/2" from the recovery pumps, and the Mk V uses a 1" PTFE/Stainless recovery hose, with two pumps drawing out of it.
I had mine made locally at Motion and Flow, but note the local Associated Hose has them cheaper.
I still like the copper crushers, maybe because we used metal crush washers extensively in aerospace manufacturing inert gas systems, especially those also seeing vacuum.
When you are counting parts per millionth atmospheric contamination, a couple small leaks add up fast and destroy product, so we did it by the numbers.
I like their product in suitable applications, but I've also ripped out perfectly good "washer-less" stainless Swagelock fittings from half a million dollar vacuum interlocked inert gas weld chambers, which also saw vibration from its pumps, and eventually started leaking at the parts per millionth levels.
What ever hose systems you chose, might I suggest regular checks with a portable HC sniffer?
Thanks for the advice! We are using the Snap-On ACT790A leak detector regularly.
We aren't using inline hose valves anymore except on the can tapper. After transitioning to stainless hoses we had to use external ball valves and I bought the same ones from paramount supply that are on the mk3 part list.
For anyone buying ball valves--always order 1 or extra as a backup. One of the ball valves we ordered came leaking.

You will also need 2 fittings for each ball valves:
Item name: 48 X 4 X 4 WTHD (very descriptive, i know)

And you'll also need a 3way Tee 1/4" JIC fitting. We got ours on eBay for $3.
I swear that's it!

We find new valves with leaking packing glands at leak check, which usually can be fixed by removing the valve handle, and tightening the gland nut underneath it.
Occasionally they can't be tightened bubble tight, so we return them to Paramount.
We switched to a three piece dump valve costing about twice as much, so that it could be both adjusted and rebuilt. You can do the same with the rest of the valves, for more money, but so far the low failure incidence hasn't justified the additional investment.
If you buy the large three piece valves from Glacier, be sure and tighten all of the bolts, as we do receive them leaking multiple places right out of the box. So far the same valve from Dixon hasn't leaked, but cost's more. I'm paying the difference on my Mk IVA test sled, just for the piece of mind.
How much for the Extractiontek? How big a unit?

^^18,5 comes with a 2500 caresaver too
I am stoked with the Bhogart!
I am stoked with the Bhogart!
I have recently learned after my 3rd run that this thing rocks! I am on to making the purest honey oil I have ever seen. I have had some reservations before I just said screw it and got more stuff, such as a vacuum oven on ebay for $250 that is tits. I am now starting to run enough to make this bad boy pay itself off 3 times over. I hope yall are running strong and keeping pics and notes! I am!
