45deg rotary bending badly!

[grandpatzer]

as you can see on left picture the bottom rotary is bending as the middle rotating space has more distance compared to the other rotary.

what should I do, keep it or replace with a straight?

Replace it. Unless you like the idea of the chance of a leak.

Replace. The cost of the replacement is minimal compared to anything else in your case.
