A regulator that converts a high pressure gases into a low pressure gases and keeps the pressure and f-low of the output gases constant. Features: Easy reading pressure gauge. Poly-carbonate flowtube and outer cover are impact resistant for maximum durability. Flowmeter is back pressure compensated to ensure accurate readings when line restrictions are present. Refined from fine quality materials, compact structure with fine sealing. Perfect alloy body, stable voltage regulation, firm and reliable. Large handle switch, anti-slip design, more labor-saving.
