I recently picked up a Perlick Growler Filler. For those folks who use of these (Perlick or otherwise) is it necessary to use Keg Lube when you plug this thing into the taps?
Secondly, what’s a good substitute for Keg Lube if I don’t have any laying around?
Keg lube substitute: petroleum jelly (Vaseline). I think Petrol Gel (sold by many LHBS in place of keg lube) is the same as Vaseline. They certainly feel the same. I have used Vaseline before in place of Petrol Gel. Seemed to work just the same.
Haven’t needed to use keg lube at all on the O-rings for the filler. I have Perlick 630 faucets and the growler filler insert fits easily and perfectly. Will likely lube the rings over time just to keep them softer and pliable but have not needed to do so thus far and have used it quite often over the last 2 - 3 months.
