Yeah- you have leaks-
Have you seen those ptfe sleeves that fit a 24/40 flange?
Super great, make a leak free seal and eliminate the need for grease, which is obnoxious and easily contaminated your product

I have a 24/40 ptfe sleeve on my BF to head connection. But I greased it so next time Iāll try without any and see if anything changes
Not CBD
Pic for fun
Not exactly mad at color but I would obviously love to do better!
Donāt run without grease.
I have not I will make sure to do that, my finger on my vac gauge just couldnāt hold past 200 micron. Gonna buy a cap for it and try.
Dm me Iāll send you one, I have a pile of em

Hey do gl 18 fittings fit on the same barb as a gl 14?
So Iāve decided on going full bore on my 2L SPD. I bought a single adapter cow, and killa12345 ss cold trap. going to be all bellow hosing, with a pressure release valve on a 4way kf25.
Problem is I totally forgot about a vacuum gauge. Iām currently using a supco copper fitting vacuum gauge. My question is if I hook up a 3/8 barb to one of the 4 way and just had a rubber line go to the gauge and a cap on the end of the gauge would that limit my micron on the machine or just limit what Iām seeing on the gauge.
Me patiently waiting for my full bore kitā¦
gotta isolate something!

Going down still by .5, this is with a 1/4 supco fitting and a 3/8 barb to pump with a vacuum rubber hose and hose clamps.
Cold start on pump
Could it be be bottleneck because of adapters? And/or hosing? Didnāt get any jumps around on micron so I donāt think leaks are an issue
Iād put it on the top with a kf25 cross and find and adapter from that to kf25 or use a kf25 to barb and set it up with a mini piece of tubing. Iād keep the spd 24/40 or larger all the way to the pump

Wonder if I could just get a 1/4 female to kf25 and acre her right in side ways. I was thinking that or like a 1/4 stainless braided water line tied to both1/4 males.
What Iām wondering if if my system is all 24/40 with bellows and my vac gauge is just a 1/4 would the reading in my vac gauge be higher micron then. What on my system actually is pulling @Killa12345 @cyclopath
That is if I have it all connect to a 3 or 4 way kf25 cross
Looks like youāre still pulling through the gauge. THAT will slow you down.
No. Going THROUGH the gauge would cause a restriction, which would lower your CFM, which would make fighting a leak or the actually boiling of stuff in your flask harder to keep up with.
The smaller the volume you need to evacuate (short, small bore tubing) the faster you will hit you ultimate vac level (blank off value).

Thank you @cyclopath Iām putting a lot of money and I keep buying outdated stuff. I really appreciate your replies 
I plan on doing a full flush with pump and seeing if I can drop the micron even more.
Have a great weekend will update thread once I pull on full system!
Just posting because this 
Cant wait to use it! It was between Davidās cold trap or @Killa12345 pretty sure I made the right decision 
Iām sure both would of been great but Iām digging this SS cold trap!

Everytime I see a heating manelt with one of those funky ass covers. I always think to myself: mother fucker, Iāll never do spd until I have one of those because it takes away needing that rope stuff.

Itās actually heated also
Total this mantle gas under 2kw hearing power and I ht 4 liters an hour np
Gonna use a different key and see if I can hit 4.5
This thing clears fraction so quick, heads and reaching temp takes like an hour max

Thanks I always heard about the stainless cold traps and always thought it would be cool to have. Shipped to my door 2-3 days, that was over the weekend also. super heavy duty cold trap and I love the lid so contain the dry ice. This cold trap is probably fine for my 2L but I would love to rock a dual stainless cold trap setupā¦ would be nasty lol
