I use mine for AC Split System installs (heat pumps), best thing since sliced bread ! I've had mine now for seven years, just had it tested &,,, as new. Performs the main functions required, Test @ 500psi, Purge & Braze (flow). This small unit is as tough as nails and pint size.Great price wise for combined Regulator And Flow meter.I cannot fault it.

Great tool

Very solid toolBeen using my other one for years daily. Just needed another for home. Professional tool for professional tradesmen.

You won't find a more convenient regulator/flowmeter to use than this. I bought the VN-500 because of the newer azeotropics that are becoming common, such as R-410A. The VN-500 makes it quick and easy to go from purging, flowing just the right amount of nitrogen to braze with, then quickly pressure testing your work with any pressure up to 500 psi. For HVAC professionals, or anyone else who needs to use nitrogen for brazing or leak testing, this regulator is for you. It requires no tools to attach to the J-valve on any size nitrogen tank; just tighten by hand. It is well worth the money.

Somebody can tell me. How to repair Nitrogen Purging Regulator leaking?That is good product, but only use two year.

This is a great combo product and a must have for hvac. Nitrogen regulator and brazing at a few psi. Can control at knob , easy screw on to tank without wrench and .. durable. Please make other hvac products like this .

I got my gauge on Saturday and actually couldn't wait to get to work today to use this.Well, simply put, this is something I have been waiting for for a long time. I did a line set today and I only needed ONE Gauge! No wrenches no back & forth changing hoses! The thing weighs like a ton! SOLID!!!!I put it through a few tests prior to hooking it up. Actually just an open-ended hose. The braze function was great. The purge function and the test function was outstanding as well. Being able to do all 3 processes without a gauge change, hose change or extra trips proved to be a real TIME and EFFORT saver. Be sure to throttle the test function through your test gauge manifold to control the pressure. I did get the 500 PSIG model after reading the various reviews. Makes sense if you are throttling via your gauge set and safer too as to not introduce a huge slug of pressure all at once. Be sure to drain off any residual pressure prior to disconnecting the gauge from the N2 tank.All in all, I would TOTALLY recommend this product to any PROFESSIONAL HVAC Tec or installer. Hands down it works awesome! I'd give it 37 stars if I could.
