Dual Output Design: This feature allows using the same regulator for two applications at the same time; You also have separate, individual control over the flow through both sides. This allows the simultaneous use of two torch set-ups operating at different flow rates or torch and purge functions without requiring the use of a second gas bottle and regulator Durable: Made of high quality Solid brass-ensures longer service life and usability,nice finish and no leaks; durable and reliable to use CGA580 Tank Fitting: Inlet Connection: CGA580 Bottle Connection for argon and argon blend bottles;Outlet Connection: Female 9/16″ x 18 nut or 5/”8 UNF-18RH – 1/4″ Hose Barb Adapters Included Pressure range: 0-4500psi; Adjustable output flow :0 to 60 cfh (cubic feet per hour);Units of measure: kPa and psi; Dual outlet flowmeter offers precise gas metering for welders and flow numbers are easy to read Supports all argon, helium, nitrogen, and argon/CO2 mixed gas tanks. This does NOT fit CO2 cylinders.Designed for heavy-duty applications where high outlet pressure is required. Perfect for MIG and TIG Welding Specification: Material: brass Size: 180x160x120mm Pressure gauge : 0 - 4500 PSI Perfect for all TIG welder and MIG Welder application. The output flow is adjustable from 10 to 60 cfh (cubic feet per hour) Fits CGA - 580 Tank Fitting so it fits all argon, helium, nitrogen, and argon/CO2 mixed gas tanks for easy connection to insert gas cylinder Package Includes: 1x Dual Output Argon Flow Meter Regulator
