I've looked at a bunch of videos about how other people installed their spigots in their HLT/MLT/BK, and I was confused with their use of the female coupling.
What purpose does it serve? Is it used partly as a washer, to press against the inside of the container? Because I don't really see another reason to use one?
if adding copper piping for a manifold to the MLT, why not use a compression tube to female and screw that onto the nipple? Same thing goes for adding a dip tube to the BK.
The only other place I could see why it would be used would be to make the HLT look nice on the inside.
If anyone could give me some insight on the matter, it would be greatly appreciated!
