The Easy Connect cylinder is a reusable, food-grade CO2 cylinder in turquoise, designed for sparkling water machines that use the Quick Connect system. Instead of screwing in under the machine, it slides into the compartment and locks in with a single motion. If your machine has been running on a pink cylinder until now, this is the model you need.
Already know your machine model? The sections below help you confirm compatibility, understand the costs and plan your refills. For a detailed comparison of the two attachment systems, read the article Which cylinder goes with which machine.
What the Easy Connect cylinder changes for a Pink System machine
At SodaStream, the Quick Connect system is also called Pink System, because the original cylinders for these machines are pink. The turquoise cylinder for Pink System machines is the direct equivalent: same slide-in and lock principle, no adapter needed.
Installation without screwing
Installation takes a few seconds. Open the machine’s compartment, slide in the cylinder, then lock it with the Easy Connect mechanism until it clicks. There is no thread to line up and no risk of overtightening the valve.
This attachment method clearly sets the Quick Connect CO2 cylinder apart from the Classic Twist cylinder, which screws onto a TR21-4 thread. Both contain the same gas and produce the same quality of bubbles; only the way they connect to the machine is different.
Food-grade gas
Carbon dioxide is a regulated food additive in Canada. Health Canada’s List of Permitted Food Additives with Other Accepted Uses names it, among other things, as a carbonating agent under good manufacturing practices. The cylinders are filled in Canada, in accordance with Canadian standards.

Machines compatible with the turquoise cylinder
The Easy Connect cylinder is designed for recent SodaStream models with the Quick Connect system. It is compatible with the following models:
- SodaStream Art
- SodaStream Terra
- SodaStream Duo
- SodaStream Gaia
- SodaStream Enso
Some electric machines, such as the E-Terra, may require you to press the button more firmly or choose a higher carbonation level, because of stiffer internal springs.
The original cylinder test
The surest way to confirm compatibility is to look at the cylinder you are replacing. If it is pink and clips in without screwing, the Easy Connect cylinder is the right fit. If it is blue or screws in under the machine, you need the purple Classic Twist cylinder instead.
| Criteria | Easy Connect cylinder | Classic Twist cylinder |
|---|---|---|
| Colour | Turquoise | Purple |
| Original cylinder replaced | Pink (Quick Connect, Pink System) | Blue (screw-in) |
| Attachment | Slide in and lock, no screwing | Screws onto a TR21-4 thread |
| Example machines | SodaStream Art, Terra, Duo, Gaia, Enso | SodaStream Fizzi, Jet, Source, Aarke, Drinkmate |
| Capacity | Up to 60 litres of water | Up to 60 litres of water |
| Price of a new cylinder | $28.50 plus deposit | $28.50 plus deposit |
Your machine isn’t on this list, or you can’t decide between two models? Rather than guessing, send your appliance’s brand and model to customer service for confirmation.
How much an Easy Connect cylinder costs
The Easy Connect CO2 cylinder sells for $28.50. When you buy a new cylinder, a $15 deposit plus tax is added; it is refunded when you return the empty cylinder.
With a capacity of up to 60 litres of sparkling water, the cost of the gas stays under $0.50 per litre for a new cylinder. Actual yield depends on the fizz level you prefer, though: the more you carbonate, the fewer litres you get per cylinder.
The cylinder and bottle bundle
If you also need a bottle, the Easy Connect cylinder and reusable bottle bundle includes a new cylinder and an 800 ml bottle. One caveat: the 800 ml bottle is not compatible with the SodaStream Duo and E-Duo. If you own one of these models, buy the cylinder on its own.

Exchanging and refilling your Quick Connect CO2 cylinder
An empty cylinder shouldn’t be thrown away. It is cleaned, refilled and put back into circulation, so you don’t have to buy a new container with every refill.
At an exchange location
More than 2,500 partner stores across Canada accept empty cylinders: grocery stores, pharmacies, convenience stores and hardware stores. You bring back the empty cylinder, leave with a full one and pay only for the refill. The exchange location map shows the nearest store.
With home delivery
If you’d rather not go out, the Plan Bulle subscription delivers full cylinders to your door, every one to four months. The first box includes a return label for empty cylinders, and each cylinder returned earns a $15 credit.
Knowing when the cylinder is empty
To check whether any gas is left, weigh the cylinder. A full cylinder weighs about 1,160 g, while an empty one weighs around 750 g. A weight close to the second number means it’s time to plan an exchange.

Storing your cylinder safely
CO2 is a compressed gas. The CCOHS carbon dioxide profile recommends keeping gas cylinders away from heat sources, avoiding temperatures above 52 °C, and storing them in a cool, dry, well-ventilated place out of direct sunlight.
At home, this means not leaving a spare cylinder in a car in the middle of summer, near a stove or against an electric baseboard heater. Don’t drop the cylinder, and never try to fill it yourself. The CO2 inside the cylinder doesn’t expire, so a spare cylinder can wait its turn without losing quality.
When to buy the Easy Connect cylinder instead of another model
Buy the Easy Connect cylinder if your machine takes a pink cylinder that clips in without screwing and is one of the SodaStream Art, Terra, Duo, Gaia or Enso models. In all other cases, the Classic Twist cylinder is the best starting point.
Once you have the right cylinder, all that’s left is to choose between in-store exchange and home delivery. If you have a question about a less common machine model, reach the team through the contact page before placing your order.
FAQ
Is the Easy Connect cylinder compatible with all SodaStream machines?
No. The Easy Connect cylinder only fits machines with the Quick Connect system, also called Pink System, whose original cylinder is pink and clips in. The SodaStream Art, Terra, Duo, Gaia and Enso models are compatible. Machines where the cylinder screws in, such as the Fizzi or the Jet, need a purple Classic Twist cylinder instead.
Do I need an adapter to use a turquoise cylinder in a Quick Connect machine?
No. The turquoise cylinder is designed specifically for the Quick Connect system and goes directly into the machine’s compartment, with no extra part. Simply slide it in, then lock it with a single motion until it clicks, without any tools. People who previously used an adapter with a screw-in cylinder can now switch to the turquoise cylinder, which is easier to install and remove.
How many litres of sparkling water does a Quick Connect CO2 cylinder make?
A Quick Connect CO2 cylinder can carbonate up to 60 litres of water. This yield varies with the fizz level you choose: very bubbly water uses more gas than lightly sparkling water. To find out whether there is still gas left, weigh the cylinder on a scale. A full cylinder weighs about 1,160 g, while an empty cylinder weighs around 750 g.
