My guess is that the maker is using different sized o-rings during production. I leave mine sitting on top of my Provari and since switching to one-holed cartos I haven't had any leaks. I'm beginning to think I got lucky, but I do agree that the o-ring in the bottom cap isn't tight enough for my preferences.Same leaky problem with my new AGR Tank and is definitely due to the sloppy fitting inner o rings. I left my tank upside down in a shot glass over night and all the juice leaked out right past the o ring. The spare o rings I have for my pyrex tanks are too thick and I'm not willing to purchase DCT tanks just to cannibalize them. Found this site: http://www.applerubber.com/products/o-rings.cfm. Anyone know which o ring material is the best/safest to use in tanks? And what size are the DCT tanks o rings or a size that gives a good seal?
The materials they have listed are Viton, Nitrile, Ethylene-Propylene, Fluorosilicone, Silicone, and Neoprene.
I went back to Applerubbers site and not sure if they sell retail. Maybe something from this site would be suitable Orings and More
I have 2 of the AGR's and have had nothing but great vaping success with both. No leaking, no flooding, nothing but lots of vapor and great taste.
Sorry others have had problems. I'm looking to pick up a few more of these soon.
I have four of these from a coop a couple months ago. I have had very little trouble. Many they are not being machined as well now ?
I'm sorry to hear that so many people are having problems with their AGR's. I have one without any leaking or feeding problems when using a Killer 705 RBA in it. Maybe I just got lucky, I don't know.
When looking for O-rings I go to The O-ring Store - Online O-rings, Hydraulic Seal Kits, and O-ring Kits, We make placing your o-ring order and getting your o-rings online easy!. I buy the ones made of Vitron. They have a good selection with different ID and thickness to choose from.
I picked Vitron because I read about it in one of the GG threads Oddy or Penalope can't remember.
When I buy the o-rings there I use the metric sizing for my Oddy and Penalope and UFS.
On my AGR the Killer 705 is very easy to adjust the o-rings hold it snug enough not to leak and just snug enough that it's very easy to adjust the Killer. I've had it for about 1 week now and I've had no problems at all filling thru the screw hole or adjusting the liquid control.
Edit: When I refill thru the screw hole of the AGR I first close the liquid control on the Killer then put the screw back on and then I open the liquid control of the Killer.
