I'm frustrated by the crappy off flavors I've gotten from standard PVC beverage tubing. If I wanted a 3oz taster pour, I'd have to dump 2oz first.
I also don't care for coiling up 10 feet of 3/16 tubing. In a perfect world, I'd like to use 4 feet of .125" ID tubing but there's no way to get 1/8" on a 1/4" barb. 3/16 is hard enough and 1/8" is 33% smaller.
I know about the epoxy mixing insert trick on the dip tubes but it adds things to the keg cleaning regiment and there's a good reason to maintain the resistance of flow for the entire liquid run. Changing velocities along the way can knock the CO2 out of solution.
Polyethylene tubing is known to contribute less flavors/aroma to beer than PVC, but it's a little harder to work with because it's rigid. I found some 1/4" OD, .17" ID tubing at Lowes and scratched my head trying to figure out how to attach it to a 1/4" barb. Here's what I came up with.
Use 3/16" ID bed tubing pieces as couplings. I was only able to push it in by 1/2" and once I put the clamp on, I can't pull it apart.
It held overnight at 13psi. However, I won't go nuts replacing all the lines until I find out what pressure blows it apart. If it will take 25psi, I'll call it good.
Five feet of this stuff pours just a touch faster than ten feet of 3/16".
