Description
Goss FM-200F Nitrogen-Saver Purge/Braze Tool
Goss FM-200F Nitrogen-Saver Purge/Braze Tool is a heavy-duty brass nitrogen-control accessory designed for HVAC, refrigeration, welding, and brazing applications. Engineered to simplify nitrogen purging and brazing, the FM-200F provides preset flow rates that change with regulator pressure, helping technicians maintain the appropriate nitrogen flow while reducing unnecessary gas consumption.
The FM-200F attaches to any nitrogen regulator with a 1/4" flare outlet and provides separate purge and braze flow rates. At regulator pressures from 100 to 300 PSI, the tool delivers approximately 30 to 70 CFH for purging and 5 to 15 CFH for brazing, depending on inlet pressure.

Two-Stage Nitrogen Flow for HVAC Work
Purge Flow
The FM-200F provides higher nitrogen flow for purging tubing before brazing. Depending on regulator pressure, purge flow ranges from approximately 30 CFH at 100 PSI to 70 CFH at 300 PSI.
Braze Flow
For brazing operations, the tool provides a lower controlled nitrogen flow ranging from approximately 5 CFH at 100 PSI to 15 CFH at 300 PSI.
Designed to Simplify Nitrogen Purging
The FM-200F eliminates the need to continually estimate nitrogen flow during purge and braze operations. Preset flow characteristics allow technicians to use regulator pressure to establish the approximate CFH required for each stage of the job.
Helps Control Nitrogen Consumption
Providing controlled purge and braze flow helps prevent excessive nitrogen use. The lower braze-flow setting maintains controlled gas delivery during brazing, while the higher purge flow provides increased volume when flushing the tubing before work begins.
Heavy-Duty Brass Construction
The Goss FM-200F features heavy-duty brass construction designed for durability and long service life in professional HVAC, refrigeration, welding, and brazing environments.
Internal Flow Filtering
Internal filtering helps maintain steady nitrogen flow through the FM-200F under varying service conditions, supporting consistent performance during both purging and brazing operations.
1/4" Flare Regulator Connection
The FM-200F is designed to attach to any compatible nitrogen regulator equipped with a 1/4" flare outlet. This allows the tool to be integrated into common HVAC and refrigeration nitrogen-service setups without requiring a dedicated regulator.
Common Applications
HVAC & Refrigeration
- Nitrogen purging
- Copper tubing preparation
- HVAC system installation
- Refrigeration service
- Professional field maintenance
Brazing & Welding
- Controlled nitrogen flow during brazing
- Tube and fitting brazing

Regulator Pressure & Flow Selection
The FM-200F flow rate is determined by the pressure supplied by the connected nitrogen regulator. At 100 PSI, the tool provides approximately 30 CFH purge and 5 CFH braze flow. At 200 PSI, flow increases to approximately 50 CFH purge and 10 CFH braze. At 300 PSI, the tool provides approximately 70 CFH purge and 15 CFH braze.
