Thanks Vossy, the tube has arrived safely.
I bought some of this tube last year for my brew kettle, and it is excellent stuff. Ref the previous comments, I am using the 1/2" bore tubing on 3/4" triclover barbs with no problems so far. It's a snug fit going on, but it goes on without too much of a problem, and I haven't had one fail yet. Cheers
