SpectrePerformance 9541 Black 3.5"-3" Coupler/Reducer

Q: is it the silicon material or the hard one???

It is silicone. It gets a little on the soft side but I have not had any problems with it. I use this for the air inlet on my turbo and it's holding up so far.

Q: How heat resistant is this material? I will be using it to connnect a parking heater to factory ductwork

I believe this is really for automotive airfilter use. The engine bay could really get hot so i think it can withstand a decent amount if heat. I had mine for years and it still looks good. Only question is how close to the heat source is it...if its not really direct i think it would be ok.
