I can't say enough good things about this line. I was very disappointed with the 3/16" pvc line I purchased through beveragefactory because of the strong plastic taste in just about every first pour no matter if it had been hours or days. Glad to say the Bev-Seal stuff adds no flavor whatsoever to my beer and I'm back to enjoying every pour.
To those attempting the 3/16" ID line to a 3/16" ID barb, the heat gun method was the trick to making things fit for me. I used a little bit of keg lube and heated up the barb itself for 10 seconds or so and used a set of needle nose to open up the very end of the tube a bit and it slid right on. I added some hose clamps just to be sure there wouldn't be any leaks and it all works great. I used 20' on one tap at around 40 degrees(12 psi) and it's a bit slow so I did 18' on the other tap and it seems to be working pretty well. When I swap out kegs next time I'll be cutting the other one down a bit. Thanks to everyone in this thread for doing the experimenting for me. It saved me some frustration.
Thanks to birdman for supplying the line, I wish I had found this stuff before wasting my money on vinyl.
