Re: tb size

yes you can...but it doesn't seal as good as a true oval would. It puts a lot of stress towards to edges of the oval as it transitions to 3"

Hmmm, any ideas where to get 4" oval to 3" round?

I just looked and oval couplers are nonexistent in this size.

Re: tb size

I guess I could get that weld a 4" aluminum transition on the end of the tubing.

Not a perfect solution, but it would work.

Re: tb size

i must have missed it, but why cant you use a 3" to 4" round? I've used 3" to 4" round on mine, a straight coupler, a 45 coupler, and currently a 90deg coupler, 25psi, and it holds fine.

RPM's A2A uses one, and i believe Kenne Bells used one on their A2A.

Re: tb size

No luck finding a oval 4" to 3" after a day of searching. going to have to use 4-3 round :(

round doesn't seal as well as the oval would and could blow off.
