Does anyone have the hot tip for sealing air bottles? In pulling 3 apart, I've found nylon seals, neoprene o-rings, gasket sealer, etc. The parts manual shows a nut, a washer and a "sealnig" (sic) ring. Is the washer a crush washer? My emergency bottle fills to about half capacity - then hisses until empty. I've been through the whole system and just replaced the bottle, but now am having redundant issues trying to seal it.


HELP!


Thanks!

I just went through this with my CJ.  Replaced the main and emergency air tanks with new stainless steel tanks.  The seals I got from Doug were stainless steel threaded plugs / fittings with copper crush washers.  
After three attempts to seal the inlet and outlet fittings I call Doug and he told me to use use the black gooey thread sealant sparingly on the threads.  
Once I did that and let the tanks sit over night I was successful in sealing the tanks on both the inlet fittings and the drain plug.  20 hours later still holding tight.
The sealant I used was obtained from O'Reilys Auto Parts and is for aviation use.  The product used is   
VersaChem  Prime Seal Type 3 for aviation  VersaChem Part Number is 34000


Hope this helps

Hey hey, so I JUST encountered the identical issue on my CJ6's emergency and main air bottles during cond insp.
I pulled the drain plugs to clean the bottles, removing non-standard lead crush washers from in the process. (They'd been there since purchase, perhaps installed by Chinese?)
After cleaning/rinsing bottles I reinstalled the plugs with PLAAF-specified copper washers.
The main bottle holds air perfectly on first try.
The emergency bottle flatly refused to hold air despite several attempts with new Cu washers... very slow leaks remained.
I finally cleaned everything with compressed air & Isopropyl alcohol, applied a high-pressure (5000 psi) PermaTex thread sealer to the drain plug threads, reinstalled w/ new Cu washer otherwise per Chinese parts manual. Once the sealant had fully set (24 hrs), it holds air 100%.
Worked for me!
