The blue screw-in cylinder — the original — in stock at 1668 1st Ave, Yorkville. Walk in, walk out. No mailing cylinders back, no waiting three days, no 60-day return deadline hanging over you.

Two ways to get it

• Exchange — $17.99. Bring us your empty blue cylinder and swap it for a full one. You pay for the gas only. This is what most of our regulars do.
• Buy outright — $31.99. No empty to trade in? Buy the cylinder and the gas together. Good as a spare so you're never caught flat.

Is blue the one you need?

Blue = screw-in. You thread it in with a twist and snug it up. It fits Fizzi, One Touch, Jet, Genesis, Source, Power and Crystal machines.

If your cylinder clicks in with one push, you need the pink Quick Connect cylinder instead — that's the one for Terra, Art, Duo, Enso, E-Terra, Mix and Gaia.

Not sure? Bring the old cylinder in and we'll match it on sight.

Details

• Carbonates up to 60 litres — roughly 126 sixteen-ounce bottles, depending on how hard you fizz it

• Carbonate your water first, add flavour after — always
