RX WELD Nitrogen Regulator with 0-600 PSI, CGA580 Inlet, 1/4-Inch Male Flare Outlet Connection, Nitrogen Tank Regulator with 5Ft Refrigeration Hose

Used this to pressure test my 2 ton mini split install. Connected well to nitrogen tank and gauge set. No leaks, appears to be pretty good quality for a DIY'er.

At first the regulator seemed like it was leaking and not working right, but eventually I got it to work. When you unscrew the valve, it does not automatically release pressure but instead will hold it. Maybe certain regulators always work like this, but I wasn't aware. So if you want to reduce pressure you'll need to vent it to the outside. Other than that, the regulator worked fine. I pressure tested copper refrigeration lines to just under 500 psi and it held without any leaks for over an hour. Definitely worth the money and will be keeping for future nitrogen needs.

Bought this to fill up my shocks and it worked as I needed it to. No leaks. It’s not very accurate and the adjustment handle is a little finicky. Seemed like it took some effort to adjust the pressure higher and would sort of jump with small turns of the handle. Not a very gradual rise of the needle. Had to play with it to get it to my desired pressure. Probably wouldn’t recommend for professional use. 4 stars for the value and the fact that it worked for my intended use.

I was working with a R134A AC system and I wanted to be able to do a nitrogen pressure test on the system before vacuum. And then I wanted to do the triple evacuation procedure which uses nitrogen to break the vacuum.I was able to rent a 40cf nitrogen tank for less than $20 locally at a welding supply shop.

Good quality for the money, works with no issues, would buy another one.

Todo excelente. Se ve de muy buena calidad.

I got this regulator for work. I do Refrigeration so i would be using it for pressure testing and purging nitrogen while brazing. The item itself is ok. It feels cheap but based on the price Im not upset about that. It regulates fine, not super accurate from what i can tell but i dont need it to be. It came damaged with the right lense cracked. The packaging was fine but the box was rather flimsy with some thin foam in it. It could have been a defective lense from the factory or damaged along the ride. Can't return it because my work hours keep me from doing so abd the gas money isnt worth it. Overall good if you cant afford a nice one or dont mind it arriving damaged.

Needed to pressurize a mini split line set. I pressurized to 500 psi easily. This comes with a yellow hose but I didn't use it. Instead connected my HVAC gauges to the regulator. This b pumps hard.
