Not sure how hot it has to get, but what about bending into a spiral in a 55gal barrel, weighing it down under something like concrete blocks, then submerging the conduit in very hot water? Then let it cool overnight or longer if needed. It would bet it’d hold its shape. That or buy the 30$ bubble snake, they seem like good folks at TeaLab.
This is all just my opinion based on a flawed memory
