Some here have simply cut off the barb with an appropriate Dremel grinding wheel, and (after dressing it off) then using a Duotight 8mm to Sankey thread adapter on the shank.
I'm planning on using the 6.5mm OD (3mm ID) EvaBarrier tubing design such that I only need about 2.5 ft of tubing per tap in my keezer. Since they don't yet have a Sankey thread adapter for this 6.5/3mm tubing, I will be using "Sankey Ball Lock Beer Side Converters" on the shanks and then using their 3mm ball lock disconnects on each side of the tubing. We'll see how this goes soon!
