Application: Nitrogen regulator is a standard pressure control valve that reduces the input pressure from a liquid or gas stored in a pressurized tank. Suitable for HVAC purging, inertization, pressure tests, leakage tests, brazing, and soldering. Accurate Pressure Gauge: Features two easy-to-read 2-inch pressure gauges, protected with scratch-resistant plastic film and rubber covers. Cylinder gauge range: 0–4000 PSI; maximum input pressure: 3000 PSI. Output gauge range: 0–600 PSI; maximum output pressure: 500 PSI. Safety output pressure: 600 PSI. Connections: CGA-580 inlet connector compatible with nitrogen, helium, and other inert gas tanks. 1/4 inch SAE male flare outlet connection with 7/16–20 threads for easy installation. Material: Constructed from solid brass for durability and reliability. Includes a safety valve that automatically releases excess pressure to prevent over-pressurization damage. User-Friendly Design: Precision-engineered for excellent gas tightness and accurate pressure readings. Designed to prevent air leakage and reading inaccuracy. Color: Gold and black. Material: Brass and plastic. Large-Style Handle: Oversized handle for easy adjustment and stable pressure control. Package Contents: 1 x Nitrogen Regulator. Other products are not included. Note: Color appearance may vary slightly due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
