DiversiTech DP-1 Nitrogen Purge Tool, Essential HVAC Equipment for Air Conditioning System Maintenance, Durable Aluminum, Red

Great upgrade to my soldering kit. Much easier to use and care than competitors. only 3 positions, no difficult adjustments. Recommended!

I bought this Nitrogen Purge tool to use while I braze and damn! it was easy to use and improved my brazing. It is a must when brazing copper lines in HVAC as less contaminants will be on your copper lines after brazing. Over all very easy to use and I highly recommend.

One fitting was loose but I tightened it up and it works great.

I really like the functions of purge, braze.Just takes some of the little extra steps you would normally have to take to run pipe on the job.

Very easy to use. As for another review about it breaking if your nitrogen tank falls over that will happen with a glass flow gauge also. Just be careful and don't knock over your tank. Should be doing that to protect your tank regulator already.

Now you have to flow nitrogen thru the hvac copper line set when brazing. This device is like a secondary inline nitrogen regulator. The 3 position dial works great. The inert gas helps the brazing rod to flow into the fittings. The line stays clean and purged with a less chance of contaminated air or solid debris entering the system. Old pro's to beginners will benefit. A must for 410a systems with a TXV.

This product works as intended. For those that are complaining that it breaks if you knock your bottle over, stop standing your bottle up. It is a pressurized tank of nitrogen. Knocking it over is dangerous. Use your brain.

Perfect tool for an HVACR technician. Easy to use no need to adjust like how flow meter are. Fast, small, just throw it in your too bag. Durable, well made. Recommend to techs that knows how to use this tool. Aloha all..
