I prefer glass if possible as long as it not freezing outside... I believe te "siun tea big gallon jars might work.. Has anyone found smaller real glass jars that will work?
Thanks yall
I doubt you could get them to seal well in a hole in glass.... even if you could drill a hole in the glass.
They are meant to be used in softer plastics, even PVC needs to have threads cut into it for the nipple threads to seal against.
If you could drill a hole in the glass, you might be able to use a rubber grommet to thread the nipple into, you'd need to size the grommet to the nipple, then size the hole to the grommet.
