The Nitrogen Purge Tool is a quick and easy way to purge copper pipes with nitrogen. Then, with a turn of the dial, quickly switch to a very low flow of nitrogen to properly braze the copper. It has a durable aluminum design so you can just throw it into your tool bag when you are done.
Purge Flow Rate
25-35 scfh (standard cubic feet per hour) 19 - 23 LPM (.03 dia. Orifice)
Braze Flow Rate
2-3 LPM (.01 dia. orifice) @ 56-60 psi regulator pressure
The purge valve is not a regulator and therefore the output pressure will equal the input pressure when the outlet is blocked. It is not intended to be used with the outlet blocked. The user should not weld a completely closed loop as the pressure will build. We recommend removing the schrader valve and letting it vent.
