High temp silicon coupling?
Ok, here's one. I know you can use the high temp silicon couplers on engine headers to hook up a tuned pipe. But, will they withstand the header temp of a 4-stroker running 15% nitro?
These puppies get pretty hot.

RE: High temp silicon coupling?
ptfe, meaning teflon? Will check out to see if they have the size I need.
I found one made of silicon by Aerotrend, and it is 1/2" ID with 13/16" OD, and that is kinda the size and wall thickness I am looking for. Just wondering if it can take the heat?

ptfe = teflon yes, as to heat Ive used them in fuselaged helis with no problem and it does get pretty hot in there, the normal and ilver coloured reinforced silicon joiners cant take the heat in that situation, size seems about the same as I remember for the Robbe product.

Actually, when I look at the picture of the Aerotrend coupler on the Tower Hobbies website, it has two kinds, one is blue silicon, the other is a cream color that is rated for 25-60% nitro applications. I think the cream colored one is made of teflon also, which is what I will probably get.
