Explain.

So what do i do with that pipe?

Nice, looks like vice grips with a groove and a male "hump" welded in to make nice beads for intercooler pipes to keep the silicon couplers from blowing off, NICE JOB, too bad it wont work on my aluminum piping :(

Yeah for the aluminum tubing I'm going to weld a bead around it.

I ran four prox. 3/4" beads on my aluminum 2-1/2" pipes and had sealing problems. I am going to sand one of my pipes smooth and try it. With a good hose clamp I can't see why a thick silicon hose will blow off even at 30+ psi.

Four beads? How do you mean? Did you weld 4 "circles" on the tube or just lay down 4 short beads with gaps inbetween?

Sorry for the confusion. Gaps in-between the 3/4" beads.

Why does that not work on AL piping?

Aluminum doesn't "work" the same way steel does.
