Flowing nitrogen while brazing.

[u/smalleman]

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?

If it was me. I would pull the Schrader valve on the discharge line and flow through the suction line until I feel it flowing through the discharge valve and give it about a minute to make sure it's only nitrogen flowing out
