You can also tell the posts apart by looking or feeling for the notches in the base of the gas/in post.

Where did you source your from? I did green for gas, red/brown for beer too.

I was on holidays in Orlando and had them shipped to my hotel from McMaster Carr

Good idea, UK customs pulled my pants that far down you could see my toes.

Hi Guys,

So I followed the advice on here, and ensured the beer was completely flat. I used the charts and looked up 2.3 vols @ 6C (43F), which gave me 12PSI. I dialed that into my regulator and it has been like that for the last 11 days. Now onto the beer line. Using this calculator: https://www.kegerators.com/beer-line-calculator/
I have 12PSI, and the internal line diameter is 0.170" (1/4" OD), and the distance between the centre of the keg and the tap is 16" (1.33 ft). Finally, leaving the flow rate at 10 seconds, popping in all those values into the calculator gives me an estimated line length of 6.31 feet.

I have 8 feet of line, plus the two adapters on either end that step the line down to the smaller diameter line from the keg, and then back up so it can join the keg. They are about 4" each, including the connectors, which is as small as I can make them. Even though there is no way to include these in the calculator, I figured that since my line length is approximately 1.7 feet over the required distance, that should offset the fact that these adapters are wider than the rest of the line.

I also added a small 12V fan which has been running for a week, to ensure the cold air is distributed evenly throughout.

So, according to that, the keg is not overly pressurised, and I have ample line setup for this pressure. And yet, when I dispense the beer, in my pint glass I get about 1" of beer, and the rest of the glass is foam. So what am I still doing wrong?

The only thing I can think of is your keg has a leak on the beer outpost so C02 is entering your beer line as you pour.

Try replacing the seals and use keg lube/cock lube.

ok. I know the seals are fine, as I check them each time I change the beer over/clean the keg, so I know htey ar not perished or in any visibly poor condition. However I don't lube the seals with cock lube or any other type of lube

I'll take it out tomorrow, put a spot of vaseline around the seal and then re-seat it. and see if that makes any difference.

It’s the one around the dip tube I’m referring to.
