I had them clamped together and torqued when I welded them. Tacked them, then welded on opposite sides in quarters. Even with the slight flexing allowed from the braided section some don't line up perfectly. I hate the bastards.

They also sell soft alum gaskets for vbands connections you can try.

I didn't cut them up because I wasn't going to use them. So I don't know. Basically a waste of $100 bucks on my part.

FWIW, I made centering rings for mine. I used the Columbia river parts. Everything lined up well after final welding if the pipes.

Of course I haven't run the car yet. So who knows if they will leak. Only have 2 in my system.

My first experience with them. There would not have been enough room for the ball and sockets.

The best thing to do is order quality vbands like these from RPS we use them often and they will not leak

exactly, use quality vbands that have a stepped shoulder, and try to use the other 1/2 together to minimize warpage while welding

Never weld a vband or any flange without the other half clamped together. Waste gates, etch, always clamped! I used to only get the shouldered ones now I just get the basic ones and slip the tube through to center it.

So heres a new dilemma. Im using 2.25 tubing for the hot side going into a divided T4 flange. What is the best way to do the transition from 2.25 to a divided flange?

Ive welded a bunch of 2.25 vbands to truck manifolds. Just be carefull lining them up and use a carbide bit to smooth out the transition.

Drop the pipe size to the size of the opening...

Another vote for clamping both sides (entire vband assembly) together while welding either side.

So just hammer out my 2.25 pipe into a rectangle to match the divided T4 flange? That's what I planned to do originally, I just wasnt sure if there was a better way to do it.

Weld away.. will be fine. Just let them cool by them selves dont water quench them they could crack right under the weld
I welded mine and been no problem
