A standard, plastic Bulb Holder for use with sparklet type 8gm CO2 gas cylinders. The bulb is placed in the holder and screwed onto a valve fitted with a "pin valve", as supplied on our basic barrels The pin pierces the cylinder and allows the CO2 into the barrel. They will not work with standard S30 valves as you need to have a pin present to pierce the bulb.
A pack of bulbs is also supplied as part of this combined package.
You will need to be VERY CAREFUL with the plastic bulb holder as it is quite easy to cross-thread it and strip the threads.
The Bulb Holder can be either Red or Black, depending on who the supplier is, but both are exactly the same size and work with all standard pin valves fitted to our barrels.
These bulbs should only be used to replenish gas pressure in a barrel once the natural pressure produced during secondary fermantation has been exhausted. If you try and add gass whilst there is still pressure in the barrel, the pressure release vent rubber will operate and let all your CO2 out. If you are trying to shortcut the serving time by avoiding secondary fermentation and immediately adding serving gas via these bulbs, you will find that you will end up using several boxes to dispense your beer.
Whilst CO2 and N2O are completely safe, when they are compressed into cylinders they fall foul of the "Hazardous Goods" regulations and cannot be shipped via the Royal Mail. If you have any CO2 or N2O cylinders in your order, you MUST choose the Courier delivery option.
