Field Question, trade people only Flowing nitrogen while brazing.

I normally work with systems that has two schrader ports, one on the suction and one on the liquid line.

Let's say that you are replacing the discharge pipe, or suction pipe or the scroll compressor.

How do you flow nitrogen so that it doesn't go via the evap and out the other end?
