I recently installed CVF’s catted DP on my 21’ Ranger. The clamps they gave me to secure the both sides of the adapter pipe which is slotted on 3 sides. I do not have a 1/2” impact so I had to use ratchet to tighten the clamps. I also broke out the breaker bar to get them tighter but I’m still getting a leak from the outlet side of DP to the adapter pipe. Is there a trick to getting these slotted pipes to seal? What am I doing wrong? Any help would be much appreciated!

On the mid pipe side, CVF sent me two of the same size clamps so I assumed they messed up. I bought this other type of clamp at AutoZone. Not 100% sure if it’s sealed completely either 🤦‍♂️

I couldn't even seal a gutter seam with that sh*t so not going to try it on a boat like in the commercial.
Really?? The aluminum boat I bought used from a guy online had a pretty big hole in it. That flex seal stuff seemed to work pretty well. Hasn’t leaked since.

Second picture shows the clamp is not fully compressed.....there is around 1/2 to 3/4 inch gaps where the clamp compresses into thay "X" shaped spacer. Clamp needs to be completly seated into the spacer groove.
You might need a proper impact wrench to tighten it thorughly....
Hard to tell from the picture if the double clamp is in need of tightening.....but a partial view indicates the same...

There is an episode of ROADKILL where Freiburger and Dulcich road trip the 71 Pontiac T37 along the east coast and Freiburger tried to patch the cracked radiator on the car with Flex Tape. It didn't work for very long. Dulcich ended up soldiering back together.
