HVAC Nitrogen Purge Regulator Kit – Precision Nitrogen Flow Control Tool

🔧 Product Highlights:

• Dual-Stage Regulation: Provides stable inlet/ outlet pressure control for consistent purging—protects system integrity and prevents backflow.

• Integrated Flow Meter: High-visibility rotameter accurately displays purge flow from 0–10 SCFH (0–5 LPM) for fine-tuned adjustments.

• Corrosion-Resistant Construction: Brass-bodied regulator with chrome-plated finish and stainless steel internals ensure long service life in harsh HVAC environments.

• Leak-Tight Design: Heavy-duty diaphragm and PTFE seals provide zero-leak purging—critical for moisture and oxygen-sensitive refrigeration and brazing tasks.

• Universal Compatibility: Standard ¼″ SAE male flare inlet and ¼″ FPT outlet ports fit all common nitrogen cylinders and purge hoses.

📐 Product Specifications:

• Inlet Pressure Range: 0–3000 PSI (0–200 bar)

• Outlet Pressure Range: 0–125 PSI (0–8.5 bar)

• Flow Range: 0–10 SCFH (0–5 LPM)

• Connections: ¼″ SAE male flare inlet; ¼″ FPT (female pipe thread) outlet

• Materials: Brass body; stainless steel spring and diaphragm; PTFE seals; polycarbonate flow tube

• Operating Temperature: –40 °C to 66 °C (–40 °F to 150 °F)

• Weight: Approx. 650 g (1.4 lbs)

🛠️ Key Uses & Benefits:

• HVAC System Purging: Displace moisture and oxygen before brazing refrigerant lines to prevent acid formation.

• Gas Shielding: Provide inert gas blanket for welding, brazing, or laboratory applications.

• Pressure Testing: Pressurize systems for leak detection with stable, adjustable nitrogen pressure.

• Fine Flow Control: Integrated flow meter allows precise tuning to match system volume and purge speed.

⚠️ Important Notes & Safety:

• Cylinder Setup: Always secure nitrogen cylinder upright and open inlet valve slowly.

• Bleed Procedure: Confirm outlet gauge reads zero before connecting/disconnecting hoses.

• Temperature Caution: Avoid exposure to direct sunlight or freezing conditions; store indoors.

• Maintenance: Periodically check seals and gauges for accuracy; have calibrated annually.
