Note when installing: When screwing in the SodaStream Type S cylinder, there will be a hissing sound of leakage, but if you ignore it and screw it in quickly to the end, the leakage will stop.
PK-102 Type S exclusive gasket, 1 unused sheet included.

I saw an article about a failure, so it is unused. I don't understand it well, so it is unused.

Since it was a system to dissolve CO2 into the line, an inline diffuser & check valve (used, 1 each) and (new, 1 each) for connecting to the external pump's IN side (thicker side, 16/22mm) are included.

As a bonus, pressure-resistant tubing and other items are included.

Thank you.
