## Questions & Answers

**Q: is it the silicon material or the hard one???**
A: 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 long is this? all the ones i find are only 3" long and I need at least 3.5 but 4 would be comfortable.**
A: The Spectre 9541 is 3" long.

**Q: Are the measurements for the inner (id) or outer (od) of each end?**
A: ID

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