Grainger doesn't have it, Northern Tool doesn't have it, and Lowes doesn't have it. Home Depot has a lower temperature (200F) Armaflex, but doesn't have HT Armaflex. (HT Armaflex, by the way, is a high-temperature rubberized pipe insulation.)
Does anyone know where I can get this stuff? :(
PS: I'm in DFW, TX.
