Carbon Dioxide S30 Cylinder

Fits the cap of any beer barrel with a CO2 injector valve (S20 or S30 type), and allows the beer to be kept with a covering of CO2, rather than air, which improves the keeping qualities of the beer as well as maintaining the 'fizz'.

If buying the refill, your existing empty cylinder must be returned to us intact and in good condition (the plastic seal around the neck must be unbroken). The £16 deposit will be refunded (re-credited to your Credit Card or PayPal account) upon receipt of the empty cylinder.

Please note, this cannot be used with inlet valves designed for CO2 'Sparklets' type bulbs. Replacement valves are available though - please phone for details.
