My pipes keep popping off under 5+ lbs. I need some suggestions. I have 4 ply silicone couplers with tbolt clamps. i will fix one and another will pop off then i fix that one and the previous one pops haha. Its very annoying when I wanna boost and then POP, no more boost.

The pipes dont have beads/lip on the end. SO im thinking thats the problem. I cleaned the oil off with brake kleen every time from the couplers. What are some options I got?

1) scuff the ends of the pipe with a grinder to create friction
2) hammer a lip on it with a ballpen hammer
3) weld a bead on it


Anyone have some ideas? what would be the best quickest cheapest way haha. I have access to welding stuff (Lincoln Electric MIG welder) I got the capabilities to weld aluminum or steel or whatever i want, along with Argon gas etc.
