NITROGEN PURGE KIT

NITROGEN FLOW METER

Model No. NFM-TT

Part No. (0386-0849)

The NFM-TT Nitrogen Flow Meter allows for a controlled ow of nitrogen gas

through copper lines during brazing and provides a visual conﬁrmation of gas

ow. Purging the line with nitrogen prevents oxidation and scale inside the

tube which would otherwise cause contamination.

• Outflow 0 to 75 SCFH and 0 to 35 LPM

• 1/4" F.F. Inlet, Max Inlet Pressure 50 PSI

• Brass Body Construction

• 1/4" M.F. Outlet

• Over-Pressure Safety Relief Valve

• Provides Visual Confirmation of Gas Flow

Nitrogen purging: When brazing copper, it is imperative to purge with nitrogen in order to minimize

or eliminate oxidation that results from heating the copper pipe. Without purging, oxidation will occur

and the oxidized ﬂakes that result can and will break off and ﬂow

through the system, damaging bearings and fouling system ﬁlters.

All that is needed is a low pressure, low volume ﬂow of nitrogen.

The use of dry nitrogen gas also minimizes the need to evacuate

moisture from the system.
