BALLIIHOO 2 Inch Pressure Barrel Co2 Control Cap - Full System with Pressure Gauge and Co2 Bulbs

These co2 injectors sell for £16 minimum elsewhere, which is not great value but is the going rate... When you add in the cost of 2 packs of co2 cartridges in (£4 minimum each from anywhere), this puts the actual cost of the injector itself at just £11. On the basis of that, this is a very good deal! Mine arrived quickly & works perfectly. Recommended!

Thought my seal was leaking so decided to get a new top and gas cartridges, only to find I have a hairline crack in the top of my barrel, the top ,valve and gas cartridges are good quality and instructions easy to follow

I got this to replace the standard cap that came with my youngs barrel. I was having problems with lack of pressure due to the old lid leaking. This replacement lid has been great since I installed it, I have not had to use the CO2 as the lid is a great fit and has kept pressure.

Decided to test with water before filling with beer. Initially the co2 would leak straight out as I tried to fill with co2. I lubed the main seal and still leaked gas around the valve. Removed valve a re-seated the black seal. After this I managed to get it to hold pressure and measure using the pressure gauge.

The valves in the cap rust very quickly, I have two of these. they are not made of suitable materials for food use. I had a leaking tap on the barrel and removed the cap to release the pressure, only to find quite heavy rust on the underside of the valve. I intended to release the pressure then re-fit the cap and turn the barrel on it's side to address the leak on the tap. After seeing the rust there was nothing I could do about the leak. I wasted nearly 40 pints of beer. I'm really not best pleased!

Easy to use. Use just enough CO2 without over pressuring the barrel. One niggle was the o-ring seal supplied was slightly under sized and would not remain in place, so I had to use one of my own. Overall, an excellent addition to my kit.

this is a good bit of kit not quite what i was looking for,i had to change the cap for my old one but as a replacement part fits and works well. the only tool needed is a adjustable spanner and hey presto it is fitted ready for use.

I THINK it’s okay now, but I did find the valve was whistling a bit on initial use, suggesting pressure was being lost . I noticed the rubber seal between the metal valve and the plastic top wasn’t evenly squeezed, but by tightening the nut more I think I’ve solved this, and that whistle has gone. However I’m yet to see if sufficient pressure is going to be maintained. Only time will tell!
