Converting hose size from CO2 tank
So I am almost done fermenting my first batch of home brew and am about to start kegging it. The only problem is the current hose coming from the regulator is a good bit wider than the nozzle I have on my homebrew keg. Is this something that can be fixed somehow, or should I look to replace one of the nozzels? Does the hose width matter much for delivering the pressure to the keg?
EDIT: connector looks like this:
EDIT: looking back on this question, I notice this picture shows a barb that could be screwed off, mine at the time was not like that, had a particular barb all connected as one piece.
