its good practice to run ofn nitrogen through the pipe as you braze it, else carbon deposits may form and may end up in the txv. always good to carry out a pt/st test too, ive had 1 or 2 brazed joints fail in the past and its cheaper than calling someone like me out to fix it. Still they are much better than flare, most callouts i get are leaking flare joints. I only use couplers on soft pipe, no swaging. Im not sure what other fridge guys say about it but id be concerned over time it will split.
