In this video I do an experiment following up on my first video about making TPU gaskets. I answer some questions and explore more about this material to see in what applications in can be used. I soaked it in fuel for 2 days to see if it would expand and do some rudimentary temperature tests on it to see what kind temperatures it can withstand.
