This place used to be aeroquip.cc and had the cheapest stainless teflon line. I think they had the one with the stripe that was for some racing sanctioning body also, but that was much more expensive. The guy told me it was the same hose but didn't undergo the testing the striped one had, that's why it was half the price, but it was the same quality. It was for some industrial use.
