Flexible PVC elliptical section around 0.275" x 0.100" with two holes inside, different sizes, die is 2X oversize (double width, wall, etc.) to make it easier to get air into holes and keep them open. Product draws down OK, cut to lengths, but they shrink 5% or more after a few days. Current thinking is to make smaller die and somehow get air in (they do even smaller ones for med tubing). Any ideas to reinforce this decision, or possible alternates?
