Juice comes into contact with that oring big time, I would be careful using silicone..Just got my 2 Boreas...............no oring in the bottom screw on base...I inspected all just for this reason and was very careful not to lose any rings. And yes it pee pee'd around it under the build deck with no O ring at all......other than than I haven't had any issue with leaking other than this. Wicking is not a problem and it works good.............BUT the way that O ring is in the base is a really, really bad deal..one the groove it sets in is wayyyy to larger for the OD diameter of the O ring (got one out of kit) and no way it will ever stay in place when the bottom is removed to rewick or coil, and I was being very careful and watching as I knew this could be an issue.....and it is......
Augvape needs to come up with a better more durable sealing method for the bottom, one with a seal that won't stick to build deck or fall out when turned up to screw back on......
OH HEY ROXY! Wanna re-post the sizes and locations of all the O rings for me sweetie (type material and size would be nice, making it a sticky would be good too...aren't most of them 1mm in thickness?)............love the tank..BUT going to need a shit load of O-rings for bottom screw on build base..............or use heat resistant automotive silicone to fill in the groove in the base and "manufacture" a more permanent one......
Even with the right size O ring I'm going to suggest some heat resistant silicone gasket maker to stick and hold that particular O ring in place as its the easiest to lose and the one most often messed with......
