Connecting regulator to 60/40 CO2 Bottle

[WelshDev]

Hi all, I need a little help.

I've got a garden bar with a Maxi 2-line cooler, 2 kegs, 60/40 gas, etc. This was all sourced and installed by a friend of a friend.

It's all been working great but I was having a little trouble getting the PSI right as I had no gauges. I then purchased a regular which was labelled as being for bars, etc. I've tried setting it up today and it's the wrong connection so I was hoping for some advice.

I've attached some pictures of the equipment I've got along with the old and new (with gauges) regulator. The new regulator came with a small attachment which says it's got an internal diameter of 21.8mm. This screws into the CO2 bottle but I don't see how it can possibly connect to the regulator itself.

I'm hoping there's some sort of adapter I can get instead of having to buy another regulator.

Any help would be greatly appreciated!

Thanks

I believe that mixed gas has a different connection to pure co2.

You have two different regs. One for CO2, the other for nitrogen. They are not interchangeable for safety reasons.

The "adapter" will screw on to a CO2 regulator (W21.8 etc. designation, W stands for Whitworth) and allow a Sodastream cylinder to be attached (Tr21-4 designation, Tr stands for "trapezoid"), and I've no idea why one has been supplied! Put it away!

It seems many gas vendors will offer nitrogen/CO2 mixes to anyone asking for beer dispense gas. Punters will often think "Like the Pubs use!" and take it. But for homebrewers you have to be well aware of what you want mixed gas for and how to use it. Otherwise, you need pure CO2. Mixed gas is a very high-pressure compressed gas (2-3,000PSI, pure CO2 will always be a liquid at around 860-900PSI at room temperature which sounds less dangerous, but it can still do a lot of damage).

Don't bodge stuff together to get the mixed gas on-line, switch to CO2 and get the right gear for it (and you seem to have got much of the right gear for CO2 already).
