💨 Efficient Nitrogen Purge Tool: Diversitech DP-1 Ensures Optimal Results Review

Don't waste your time and money on this. I adjusted my regulator's inlet pressure to 60psi, it still flows at high pressure to silver braze the HVAC tubes. I went back to my flow meter and set it to 6 cfm. waste of time and money.

Really great for light blowing or soldering but for a good pressure test just remove and use a full size regulator. Would buy again.

Bought this little tool while installing my HVAC. Used it for solder lines or solder lines ie. They attach it to a nitrogen bottle and purge the lines with nitrogen to avoid contamination when soldering the lines.

I like this product very much, easy to use, quick to put on and take off or to blow/solder. The problem I have is that if your tank tips over, one of the fittings will come loose. I've seen 2 of them do just that. The fitting is about 1/4" in diameter and is brass. Maybe it should be stainless steel. It would be more durable. Don't know if the part can be replaced, all junk.
