I'm looking for some options. I have dry exhaust and I'm installing trim rings around them on the transom. Is there a preferred rubber that seals the pipe with the trim ring? I was thinking a heavy duty tractor innertube material. thoughts?
thx,
Tom

We used something like this, SS trim ring with a rubber seal. I still put just a very light bead of life seal on it.

What size 4 inch 4.5 ? I might have some new ones

Thanks Guys. I'm struggling a bit. I have my pipes coming out of the upper transom at about a 40 degree slant. ( Activator) I'm working with Stainless Marine on the trim rings and they don't have anymore gasket material. And i got the last of the trim rings as well. Letty said it was some crazy 1/4 inch stuff which i can't get my head around. Anyway just received my trim rings and one is a different size so I'll be going back and forth on that deal till i get what i need. Anyway what are your thoughts on the innertube idea? Im going to go down the street to the tire shop and ask them what the thickest tube they have and buy one. I'll cut it up and use that.

I buy that stuff from Mc Master .
If you`re dry exhaust that intertube material will burn up pretty quick.

I did all the homework for you since ive spent a buncch of $$ seeing what material and thinckness is best.

I will start a thread in the Activator forum eventually 4yr project. This one kicked my arse
