I have valves and a gauge on mine so I can isolate it.
I think some here maybe @Soxhlet said you want hemispheric bowl end caps but you want a pretty fine gaskets to catch the dust but that is all mine is.
A tri clamp spool, some clamps, valves, fittings, gauge and zeolite beads. Really nothing special to it.
Do you know why you want hemispherical end caps?
It’s something about the flow characteristic. There is a thread about this sometime right around this time last year. It should be in the early threads on this site.
Personally I have no clue. I’m guilty of following the leaders on this one.
So you run through the sieve every pass? Or is it a maintenance thing you do every x amount of lbs run through the system?
Every single damn time set up Inline. Also make sure your beads are kept charged to keep them working
@anon60420198 maybe start here? Jacketed dessicant - #13 by SkyHighLer
how is this done?
see: Molecular sieve beads - #24 by cyclopath
I think he’s referring to drying them back out. Baking desiccant at 250f or so usually does it.
Yes, that is my interpretation of @Cruzinlabs comment also.
But @anon60420198, not being a current sieve user, might not know that.
so I linked to how to do it…
Is it cheaper to piece together the stuff needed or to just buy a molecular sieve filter dryer already made?
I’m wondering how important the hemispherical end caps are. I’m piecing together something now on bvv and they only have the flat 1/2 fnpt caps.
What size do you need??

Yea that is what I meant dry them out. Sorry I refer to it as charging them and ready for use and uncharged for not ready.
You can build them yes,… But the hemi caps (makes sure you don’t have poolingor gas sticking,and that all the gas makes it through evenly)alone cost me $150 for both,jics, adapters for them, clamps, PTFE gaskets, lil piece coffee filter at each end for extra help too…
And you have to pressure test for safety and efficiency of running if your building yourself, add that into the cost and…
…Personally ,@Killa12345 badass dude, I think he has some ready to roll… Best way to go, save some money and make your stuff right…
Thats what i run and ny gas is as dry as the sahara
Hemi lid is very important it creates a vortex so tour gas doesnt find the path of keast resistance and it “recycles” its self theu the beads to ensure all vapor touches the beads.
Idk about using silicone, PTFE envelope , PTFE only for me, maybe viton up top
It’s almost like those cheap sight glasses bestvaluevacs makes, why the f*** are they even offered on an extractor
No! No! No!
Do not use silicone with hydrocarbons.
Unless you’re looking to make up for the lack of a PRV.
Had a major manufacturer ship a rig with a couple of silicone gaskets in it. Pulled parts of them out of the filter after the first solvent run through.
Explained the leaks that hadn’t shown up with 200psi nitrogen…
Silicone gets a D with Butane.
(D =Severe effect; not recommended)

Even terps will eat it!
thank you i had no idea in that case can anyone make me three 5 micron 2500 mesh 1.5" triclamp gaskets out of ptfe?
Put coffee filter at each end
