The new and improved WilliamsWarn® Soda Stream Adaptor has a fundamental design improvement to eradicate lost gas through the connector: a side adjustment for the pin valve into the soda stream bottle enables the pin valve to be engaged once the cylinder, adaptor and regulator have been screwed together. This ensures that the gas supply from bottle to the regulator can be engaged and disengaged whilst fully connected. Prior third-party versions of this Adaptor - which have been in our industry for the past 15 years - did not allow adjustment whilst connected which would often lead to C02 gas being leaked.
NOTE: This can NOT be used to refill a Soda Stream Bottle from a bigger cylinder.
