Saw it, recorded it.
Seemed as if it had some truth mixed in, which is very rare on telebision.

I loved the o-ring trick, even though a decent engineer could have blown him out of the water with technical details.
Chances are it was neoprene if he got it from the local hardware store, and no way would they be using neoprene in the presence of hydrocarbon. Most likely perfluroelastomer (cubic $$$) like DuPont's Kalrez (tm) which can take much lower temps and remain flexible and retain memory.

It was probably dumbed down for TV.
