Our replacement CO₂ cartridge holder is designed for vintage BOC / Sparklets-style soda siphons. It is also compatible with older LISS siphons and a range of other vintage soda siphon models.

This is an aftermarket replacement part, as the original manufacturer is no longer in business.

The holder is guaranteed to fit BOC / Sparklets soda siphons manufactured between 1965 and 1985.

Please be aware:

Although this CO₂ cartridge holder may fit older soda siphons, the condition of vintage siphons can vary considerably depending on their age, use and how they have been stored.

Older siphons may be unsafe to use under high pressure and could potentially fail or rupture. For this reason, we recommend treating vintage soda siphons as collectable or decorative items rather than functional kitchen equipment.

For regular use, we recommend purchasing a new soda siphon from our Pro Fizz or iSi range. These are designed for safe use with compatible CO₂ soda cartridges and CO₂ bulbs.
