Help with Boddingtons Keg please?

Oh yeah, you need a "G" sanke coupler. It is a slider. Easy to find, just google Sanke G coupler and there you go. Then swap out your current coupler (which is a "D" coupler) for the G style. Be sure to tighten everything and replace the washers. Don't lose the washers.
Sanke couplers are standardized and are in fact not standard for all beers. So 99.9% of domestic beers will do fine with that D style, while UK and German beers require other styles. More than 1 variety even within countries. .

That part is pretty easy.
You need beer gas.
You need a regulator for the beer gas.
You need a stout faucet.
I am assuming you have neither.

Search this forum for a few dozen threads that have previously covered every possible beer gas question.
Pro-tip. Do not push Boddingtons with CO2 gas. Not even for a little bit.
Cheers.

 

Before you buy anything, read this article:

Next step is to determine how you will be supplied. You need beer gas which is a blend of Nitrogen/CO2. You want to know if the supplier "exchanges" tanks or "fills" individual tanks. This determines if you need your own tank or will "buy in" to an exchange. If you take a new tank to an exchange supplier you will wave bye-bye to it before it's ever filled. There may be limited availability of beer gas unless you live in a large city. If you hit a dead end you might inquire at bars that serve nitros.

 

Beer Gas is aka Guinness gas. A decent gas supplier, your local welding supply or fire apparatus supplier, they will have beer gas. You must get 25% CO2 75% Nitrogen. Nothing else and it is what makes the Guinnes style draft beer pour like it does. This gas won't work for regular keg beer either. 100% nitrogen is not a substitute. Advance notice, ask for 25% CO2 75% Nitrogen and you may get questioned by the sales person... ignore it. You want 25/75. This is important. If they do not have it, move on. It is not uncommon in the beer world but it is a blend gsd that some suppliers may not carry.

Most but not all beer gas cylinders are female thread... a Nitrogen regulator is needed. The N regulator is Male thread, etc.

Stout faucet, buy a s/s faucet if you can. Spend the extra $15. A company called Krome makes a very nice budget s/s nitro faucet. Buy a faucet wrench if you don't have one.

Cheers

The equipment in your link shows an adapter that allows a CO2 regulator to be used on a nitrogen (beer gas) cylinder. Background: Gas cylinders all have different fittings depending on the gas in use. This is to prevent inadvertently filling the wrong gas in a cylinder. Regulators are made to match these unique fittings . . . this is what prevents you from putting an oxygen reg on a nitrogen tank, or a CO2 reg on an air tank. My scuba tank would be ideal to store CO2, but the fitting are such it would be impossible to fill/use with a CO2 regulator. This is industries' approach to protecting the children.

You can find adapters to allow a CO2 reg to mate with a nitrogen cylinder (beer gas), just like you can get an adapter to mate a nitro reg to a CO2 tank. If you intend to drink nitro brews only go nitro reg and nitrogen tank and skip the adapter. Only if you want to mix/match regulators with different gas cylinders do you want an adapter.

Caveat: I don't dispense with nitro (CO2 only brewer) and will let @billandsuz speak to the practicality of adapting a CO2 reg to a nitrogen cylinder. Also, be prepared to pay more for beer gas than straight CO2 . . . why? . .. because they can.
