RX WELD Nitrogen Purge Tool, HVAC Brazing Regulator

Works great

I bought this for my hubby. He has found it to be very useful and the durability is top notch. It was a good value, easy to use.

I bought this before.... it works good but don't drop it......it'll break pretty easy.

Just as described

Great product for a reasonable price. I use it almost daily and have had zero issues.

all good

Can be used to maintain test pressure of 150 pounds with a slow feed, while searching for a small leak. Instructions say 150 pounds maximum. Has three settings: off, purge (slow) and braze (faster). Purge and braze can be sped up or slowed down by regulating feed pressure to the device. I found that a slow purge requires only a low feed pressure to this device, just enough to get the pressure regulator to flow to it is enough. The braze setting has a much higher flow rate than I expected.

I've had other ones that were made of better quality and durable this one seems cheaply made. I question how accurate the airflow is, when brazing there seems to be a lot more flow of nitrogen than is needed.
