Great regulator. I've used this now around 3 times. I've used it to blow out drains. I haven't had to use it for brazing yet. That will fish's come next week. I'll be overly happy with this regulator if it performs just as well with brazing and pressure testing as it has with drain clearing. So far I recommend it. It's cheaper than other competitors. It's very well built and would probably hold up well to abuse. I don't plan on testing that, lol. I was a paramedic for 10yrs before becoming an HVAC technician. The quality of this regulator reminds me of the regulators we would use on our portable o2 bottles and the wall mounted o2 regulators. It's a great product. I recommend it for the price!
