So I have the below regulator:


I'm relatively new to legging, as in this is my first attempt. I was force carbing a keg this afternoon and the line literally exploded off of the connector. The plastic valve along with the metal fitting stayed on the keg, but the hose went flying, and as a result a lot of great smelling beer was lost. Sad face.

Anyway, I just wanted to know if I'm reading this wrong or doing something wrong to have caused this accident. Looking at the regulator, I've been using the top one as the reference to what's going in the keg and the side gauge as the one measuring the tank level. I filled the keg about a week ago to 18 psi, so I think anyway, and let it sit lagering for a few more days. Today, I cranked the nozzle to 28 psi to begin the process of force carbonation. I didn't hear much gas going in, but assumed I was just missing something. I started rolling it on my knees and that's when the explosion happened. I immediately looked at the tank and the top valve still read 28 psi, but the side tank was reading near 50.

So, did I just dump 50 psi into my beer and therefore ruin it, or do I just need to get some clamps on my hoses?

Thanks all

What kind of clamps do you have securing the gas hose to the fittings? If worm type clamps, there's the issue. Either they were not tight enough (can be difficult at times, depending on which ones you got) or it simply failed. I've been using oetiker clamps, with a crimping tool, and have no issues even at 30psi. They work far better than worm clamps, since they secure all the way around the hose, not just partially (as worm clamps do).

BTW, the gauge to the left is the high pressure side (shows what's in the tank). The one directly above the barbed fittings is the low pressure side, which is what's going to the lines.

Also, the numbers on the outside of the marks are in 'bars' where the inside is PSI. 50 bars is about right for a full tank. 50psi would be empty.

Oetiker clamps are definitely the way to go and you don't need the expensive crimp tool to use them. You can crimp the clamps with a medium size set of wire cutters.

Keg Connection has the non-ratchetking tool for all of $8.95. It's the one I've been using for mine. Works really well to both crimp and cut the clamps.

So you all would say it's safe to say that I didn't just dump 50 psi into my beer and almost blow up my keg, but instead I should have clamped my hose. That makes me feel a lot better. The kit I bought didn't come with clamps for those hoses, which surprised me. But, it was my first time so what do I know?

Thanks.

The 50 you read on the tank pressure gauge is 50 BAR and not 50PSI. That's reading tank pressure.

The 28 psi on the other side is what was going into your keg and it's plenty of pressure to blow a hose off a barb that doesn't have a clamp on it.

Side note... you're not going to be thrilled with the old 28psi shake the keg carbonation method. The next post is going to be something like "Why am I getting nothing but foam in the glass?"

I'm sure you're right....I'm just very impatient to try my first keg. I also know this is a horrible reason to rush as I'll ruin perfectly good beer. Impatient none the less. If I've already pumped 30 psi in and then let it sit for a while, will that still work?

I'm sure the kit assumed serving pressures of 8-12 psi, so clamps aren't "mandatory" in those situations.

Even if you did push 50psi in to the beer, its not ruined. If you ever overcarb a beer, you just keep bleeding off the CO2 until it's correct.

Also I believe the safety valve on corny kegs will blow at about 130psi.

Did you disconnect the gas after putting 18 psi on it, or did you leave the gas connected for the week? It kinda sounds like you left it on the gas, in which case your beer was probably already carbed (or overcarbed) before trying to shake it.

I'm a fan of the set and forget method of carbonation, but in the rare cases I'm in a hurry I use the same relatively safe method used by many on this site. Chill the beer to serving temp, put it on 30 psi for ~36 hrs, vent the keg and reset to serving pressure. Another day or two at serving pressure and it's ready to go.
