Can gasket such as the Rutland Grapho-Glas (http://www.tractorsupply.com/rutlan...-stove-rope-gasket-kit-1-2-in-x-7-ft--3198284) be used as a replacement or does it need to be the stuff from the stove manufacturer? Looks like Travis industries has their own that I just used but TSC sells the Rutland stuff.
