Growler Fill for Perlicks

Was wondering if any of you have a recommendation for tubing to use off a 630 or 650 Perlick faucet into a growler? I bought a growler filler that was supposed to fit perlicks but doesnt seem to so was wondering if people recommended some tubing of a specific size that could fit on the faucet?

I use an 8" length of 3/8 silicone tubing - the high temp kind, it’s easy to work with.  It’s snipped about 1/4" on one end to make it easier to put on, but fits snug.
