    • Tested and Recommended – A Must-Have Regulator for Every HVAC Pro
Review Image by Andrei Golubev Andrei Golubev
Review Image by Andrei Golubev Andrei Golubev
It might seem a bit pricey at first, but this regulator is absolutely worth it — much more convenient compared to a standard one: 1. No special wrench needed — easy to tighten and install by hand. 2. Safety feature — if you forget to close the tank valve but the regulator is set to OFF, no gas will come out. 3. Compact size — much smaller than regular regulators, making it easier to transport when you have lots of other equipment. 4. Durable gauge — clearly shows the remaining gas and is hard to break during transport. 5. Purge mode available — perfect for welding when you need quick and accurate purging. Highly recommend it! Great convenience, safety, and build quality. ... show more

    • I hate China made
I used it for one month and it sprung a leak at the gauge. Not at the connector, but inside the gauge. I had to buy a new, but different gauge to replace it. Edit: The seller saw my post and had refunded my money back. That’s just awesome consumer service. Thank you.

    • The unit I received not stop nitrogen flow at 650PSI, in any setting.
The cut off pressure should be very near to 650PSI when testing, it simply lets the pressure climb, I closed the nitrogen gas tank valve at 705PSI. This unit is dangerous.
