Need it or you'll be leaking.

my search resulted in one post saying i dont need them because the ls6 tubes come w/ orings. i know lots of you members have done this swap so what did you do. thanks.

I've actually removed the o-ring and replaced with the "coke tabs", worked fine, no leaking. But that's because I was reusing a piece and I recall the o-ring looked unusable.

I'd say if your NEW pieces have a good condition o-ring on it, you're fine to just use that. If they're not in good condition, you can replace the o-ring or replace with a "coke tab" safely. I keep a supply of coke tabs because when I get the chance, I replace my LS6 coolant crossovers with LS1 tubes

Correct!!!! Coke tabs are for older LS1 style tubes.

I reused the stock LS1 tubes, cut & crimped them. Picked up the Dorman gaskets to replace the stockers, for cheap insurance. I have no experience with the LS6 tubes, however. This post is solely to offer an alternative option for finding the coolant crossover tube gasket.

I used the LS6 coolant line/ plugs with the built in O rings. No leaks.

I stand corrected. I had a Ls6 setup that came on a motor I have and when I pulled it apart it had the "coke tabs". I guess it was an older version and there are different gens of LS6 tubes? Built in o-ring sounds nice... Those tabs are a rip off from the dealer

There was a p/n change on the tubes a few years back. That's probably when the seal type changed.

Thanks for the replies I'm removing the coke tabs and just going with the oring that comes on new ls6 tube.
