Ok, I've been doing this stuff awhile now and finally found a way to make armaflex look good on elbows near the end of the lineset at the condenser or coil connection.

- Slide an armaflex tube over the copper back enough for you to complete your brazing.

- Braze, let the copper cool.

- Slide the piece of armaflex ALL THE WAY BACK to the condenser (Instead of trying to make 45º and 90º on the wall of the armaflex at the condenser connection.)

- Fill in the missing armaflex that is missing between the new piece and the rest of lineset with a straight piece (much easier to make a joint on armaflex when the pipe is straight rather than at a 90º bend)
