The answer to this question actually depends on what your tube is made from. If you have a PVC tube, you need a PVC patch and if you have a hypalon tube, you need a hypalon patch.
Whilst I rate hypalon more highly than PVC, I wouldn't recommend using a hypalon patch on a PVC tube! It's important to use the right material.
