Another newB basic ...

[customclimates]

So after a year into the hobby there is still soooo much to learn. I am totally comfortable admitting when I do not understand something I ask A LOT of questions. Here is a newB question for sure but I want to make sure before I just assume…
I am setting up a calcium reactor for the first time and wanted to know what do you seal the threads with on the Co2 tank to ensure a leak free fit to the regulator? I was thinking rectorseal typically used on gas piping threads.

Still need to go out & get a probe before I can finish this today anyways!!

Some one else with better knowledge I hope will chime in . BUt I was told NOT to use anything on the threads of the CO2 BUT I use teflon because I can not seem to get a complete seal without any leakage without it

Thanks Dawn, I know there is a white plastic washer to seal the two but I was under the assumption you still needed something on the threads.

You aren't supposed to need anything because the plastic washer should do the job. But I always used Teflon tape because it made it easier to thread.

you should'nt need anything.
Personally i would not use teflon tape either as there is a good chance that shreds of it could end up inside your regulator causing a blockage that is likely not removable.

Those threads are NOT designed to seal or is it remotely necessary that they do, this is whats called a "FACE SEAL" all thats required is a new clean gasket and snug fit, save your teflon tape for pipe threads (tapered threads).

I figured just like my Turbo MC or B tanks that it would need some kind of leak lock. I will just test it with gas leak detector ( bubbles )

 

[smcnally]

Like I said, I didn't use mine to seal but more so it threaded easily. I wouldn't listen to Liam...he doesn't even have a tank.

In a pinch you can ususally fit a O-ring in the little grove on the face of the mating surfaces. This is what I've always done.

I used an O-ring on mine as well. I learned that my regulator didnt seal well, after going through a 20lb tank in a month....
