BETOOLL Nitrogen Regulator with 0-600 PSI Delivery Pressure Equipment Brass Inlet Outlet Connection Gauges

not much else to say. it works great

This was a nice find! The machining, finish, gauges, and included hose seem to be of good quality and are very nice looking. The low pressure regulator adjustment action was nice and smooth. I will not need to use this regulator on a daily basis but it looks like it is durable and built to last. I bought this regulator to attach to a N2 (nitrogen) gas cylinder specifically for use in testing an auto A/C system for leaks but it will come in handy for a number of different needs like filling the tires of our vehicles with nitrogen instead of regular air. Unfortunately, I didn't realize the thread on my A/C manifold gauge set for the yellow vacuum/charge hose has a 1/2" ACME thread and the hose that is included with this regulator is a 1/4" swage thread. This was my fault for not checking the threads before I purchased the regulator. Anyways, with adapters it all worked out and I am happy with this purchase.

Quality built. Smooth operation when setting pressures. No internal or external leakage. Great for checking system leaks before adding refrigerant.

*** 2 stars taken off because I bought 2 and both has the right pressure gauge cracked per my photos. Amazon is taking them back no issues, but this is for sure frustrating and I'm hoping the third one I get doesn't have this issue. They're packaged very well so I think it's just bad QC at the factory. ** Update: third gauge set received, this time both gauges had cracked window edges. I'm just going to keep one and live with it for the price... ** Update 2: customer service reached out promptly to remediate my experience, and assured me they're looking into the manufacturing problem. Giving 1 star back for great customer service. --------- I'm reviewing the 800 PSI version, which the product description says has a max output of 700psi. I can't speak to the 600 PSI version. For HVAC pressure test, I need to test between 550-600 PSI, so I bought the 800PSI version. In my preliminary quick test, the pressure release valve opens right at 700 PSI, and closes again somewhere between 630-650 PSI (see photos). This is more than enough for what I need, but I believe you can take off the pressure relief valve and adjust it higher if needed. Accuracy wise, the gauge reads almost exactly what my Yellow Jacket gauge reads, so no issues there. I used a drop of HVAC oil before inserting the knob, which is pressure rated. Worked great and didn't have issues with turning the knob all the way to 700 PSI and beyond. The knob can definitely go further so no issues there. Overall incredible value for the money, minus the cracked gauges QC issues.

Good unit, use it to nitrogen charge AC systems and nitrogen charge accumulators.

Unfortunately it came with a bent internal plate. The peice that states what psi it is at one of the gauges. Unfortunately for me I did not see it until I went to use it which was out of exchange period. Still used it but since I couldn't see where I was at in psi for nitrogen. I drained my tank very quickly and messed up my copper soldering. It's my fault for not checking when it was delivered and im sure it was an accident. Ironically their fuel gauge I bought as well busted off the hose n sprayed diesel everywhere. These products are good for cheap but just be cautious like any other product out there.

Well made. Easy to read gauges.

Excellent for my DIY needs. I am an old certified mechanic (left the trade long ago) but kept myself current with tech. Anyways I feel qualified to give this regulator a solid recommendation as it the job done for small capital outlay. Helped get our ram air suspension fixed.

Workd great

Reasonable quality for the price but thread 2mm bigger than my Hobbyweld Nitrogen cylinder. Easy to return however.

The main regulator is of good quality brass. The safety valve was set at 350psi. Adjusting it to around 450psi was possible, but reaching 600psi required the valve to be shortened. The gauges are low quality. As noted by others, it's stiff to achieve high pressure, but applying grease to the thread fixed that. Note that the threads are Yankee sizes, I had to change the main nut for an EU cylinder fit and get an adapter for the outlet.

ME GUSTO MUCHO TODO ES COMO LO DESCRIBEN

Main cylinder pressure gauge was completely bent and no noticeable damage on the packing. Very weak structure. The line pressure gauge needle was below the stopper pin. Was a cheap gamble and didn't pay off.
