Subbing to keep the info, just wanted to say, thanks for asking this!
Papa, are you using the vapage bottles? Someone else was telling me about some from FT but I need to find out which ones precisely.
also, just to make sure this would also apply to the minis correct except for the o ring size. Anyone know what size the o ring is for the minis bottles? The regular size like ID OD etc would be good, but
@Rule62 if you happen to know the home depot size for those that would be great too. If not, no biggie. Thanks y'all
ETA: adding this for my own knowledge, but also in case anyone else can use it, someone had a button cover where the hole was a bit too deep and someone suggested using an oring inside the button cover size:
Sounds like you need about 1/16" thick
1/8 ID X 1/4 OD X 1/16 CS fits perfectly
