PSP responded to my email and apparently it is supposed to look like that. They said:
"Hello,
I apologize for the delay as I didn’t see your first email.
In reference to your picture. The part is not damaged or improperly QC’d.
That is a 135 degree 1D bend on a 2” aluminum pipe. You can not bead roll it completely. It is just a limitation of manufacturing.
We have tested it over and over and there are zero issues with it. Every stg3 aluminum outlet we have ever produced is not completely bead rolled and there have been zero failures or leaks.
