Not played with cans before.

On the header pipe do you force the teflon tube over the raised portion and then clamp or does it just slide on 1/2"?
Doesnt seem like much is inserted to hold it if you only slide the coupler up to the raised section.

Thanks

i slide 1/2 over the header and the other 1/2 over the can or pipe with those clamps holding everything.....

Yes, the raised portion on the headers is a help to retain and keep the Teflon tubing from sliding op. Cans and pipes will often have some kind of knurling to obtain the same result. Make sure header and can/pipe don't touch each other when assembled.
