Pressure regulator with 2 pressure gauges for CO2 aquarium plant fertiliser systems. The pressure reducer reduces the cylinder pressure from approx. 60 bar (displayed on pressure gauge 1) to a low 1.2 bar working pressure (displayed on pressure gauge 2), so that the CO2 supply can be easily regulated. Screw the pressure reducer onto the pressurised CO2 cylinder and regulate the amount of CO2 added at the fine needle valve. The pressure reducer fits disposable CO2 cylinders (U system) and refillable cylinders (M system). By unscrewing the knurled nut (W21.8x1/14) with an Allen key, the pressure reducer fits the M10x1 thread of the disposable cylinders. Very high quality design: anodised aluminium, precisely CNC milled in titanium colour. Reliable sealing washer instead of O-ring. Package contents: 1 CO2 pressure reducer with 2 pressure gauges (for working & cylinder pressure) for refillable cylinders, with unscrewable adapter - then suitable for disposable CO2 cylinders
