Fistula for filling pink cartridges 425g The only such fistula on the market equipped with hooks to protect the cartridge against accidental disconnection and a pin opening the cartridge valve. Opening pin valve increases the throughput of the fistula and allows you to fill the cartridge to a greater extent. Hatches, on the other hand, protect the cartridge against accidental disengagement. Thanks to the PCP 8mm quick coupler, you can expand the fistula with the function of filling blue cylinders (Twist, Pin) at a low cost. PRODUCT CODE: 000209 Technical data: Input: Thread W21.8 Output: Socket Quick Connect Vent: YES Pressure gauge: YES Weight: 333g Overall length: 16cm Material: Aluminium, stal stainless steel and brass Sealing: O-rings Cylinder lock: YES Valve opening pin: YES Spare seals: YES If you have a cylinder without a siphon before opening the valve, turn it upside down so that liquid carbon dioxide is forced into the cartridge. If we want to fill the cartridge to full, i.e. press 425g of carbon dioxide into it, the cartridge should be cold and the cylinder with a heat siphon (the temperature difference should be 30-40 degrees Celsius). Do not overfill the cartridge (inject more than 425g into it) this may cause the safety valve to open (the safety valve in the cartridge is disposable, it is this small screw). In case of overfilling of the cartridge, excess carbon dioxide should be drained immediately. Liquid carbon dioxide accounts for 80% of the weight of the entire cylinder content, the remaining 20% is dioxide in the form of gas. When only dioxide in the form of gas is left in the cylinder, we will press max 50g CO2 into the cartridge at once. Cartridge filling procedure: Screw the fistula into the cylinder. Insert the cartridge into the Quick Connect slot. Tighten the valve opening pin, this will lock the latches. Check that the vent valve is turned off if not, turn it off. Gently unscrew the valve in the cylinder (you will hear hissing). After the filling process is complete, turn off the cylinder. Unscrew the valve opening pin, this will release the latches Unscrew the vent - you will hear hissing for 1 second (if it hisses all the time, you did not turn off the cylinder). Remove the cartridge from the Quick Connect slot
