CO2 Quick Refilling Adapter W21.8-14

This metal CO2 quick refilling adapter (type W21.8-14) is designed specifically for refilling 60L pink CO2 cylinders used with Terra, Duo, Art, E-Terra and E-Duo soda siphons. It measures approximately 8.5 cm in length and weighs around 180 g. Constructed from polished and electroplated metal, it delivers strong corrosion resistance for long-term reliability. The adapter features an integrated pressure gauge for real-time monitoring during refill, and includes three replaceable O-ring rubber rings to ensure secure, leak-resistant sealing. For optimal performance, chill the pink cylinder in the freezer for 24 hours before refilling and maintain a 45-degree angle during charging — following these steps improves CO2 transfer efficiency and maximises cylinder capacity.
