It's an option, but I am trying to stay with all silicone if possible.

If want one like what is on the F-bomb, it is just a matter of Circumfrence.

Figure out the circumference of the oval and the buy the round section of silicone tubing with that same measurement. If you mash the silicone round hose it will make an oval. It might actually be a 3" hose that could fit on a
4" x 2" oval. If not do a metal reducer after the silcone section.

Treadstone aluminum has quite a selection of silcone hose and aluminum tubing.

Hey Rodger,

Yeah I talked to a couple places and they had me measure the circumference and divide by 3.14 (pi). This is the number that would be ideal for a round transition size. For me this number is 4.26". And no one makes a 4.25" piece so we are gonna try to do a 4" and make it fit with some massaging and lube (that's what she said ).

I would rather not do 2 pieces and keep this transition short and allow more of the stainless piping to be exposes than silicone.

Wanted to report back and say I found the perfect piece. It was a 4" to 3" reducer with the "hump" in it, and its length was about 4-1/8" which turned out about perfect. TurboHoses in Livermore had this one piece on their shelf as just a leftover part.

just use a regular round/round silicone reducer... believe it or not, it will fit an oval (sorry for the sarcasm.. but its flexible, believe me, i know from first hand experience, it fits)

Thanks, but had you read my post right above yours, you'd see that I did get a round to round reducer and it it fits nicely.
