Nitrogen brazing on open lines

[gregg1908]

Can anyone shed light on any fittings available to hook up to open lines were the outside unit isn’t fitted yet . So basically to braze on the outlet lines of the indoor unit only.

You shouldnt need a high pressure, so you might be able to just tape a gauge hose in/on the pipe. If the hose end is too big, connect a shrader valve with a copper tail to the gauge hose.
