Pressure Question

[nukinfuts29]

Does anyone here think, or know, if a round coleman cooler (like the kind used as mash tuns) could handle 2 to 5 pounds of pressure?

I am thinking of replacing the spigot on mine with a good quality valve, sealing the lid, and using it as a simple, low cost, party keg. I have an extra one, so my general plan is to fill it and force carbonate whatever is in there at around 3 PSI.

Thoughts?

IMO, extremely bad idea... So many ways for it to fail on you (in so many bad ways) that it would take more time to list than I care to spend thinking about it. I would say it would be better to set it up as a portable kegorator, housing a corny keg and serve the brew that way.

I am not sure but I would seriously doubt it. Probably can "take" the pressure but you would never get a good deal on the lid.

If you don't want to take the time to explain, then you are pretty much wasting my time reading it. If it fails in a test cage, who cares? Thanks again, very helpful.

The lid will be incredibly easy to seal. As far as leaks I worry more about the valve.

High praise for being a cheap, penny-pinching, person, but damn! I agree with above. Get some used ?Grolsch?/Heineken mini kegs and get creative with them. There are lots of ideas for those on the Internet and probably here in old threads.

I stand behind my assessment of it being a bad idea (at best)... These things are not designed to hold pressure like you're talking about. Plus, in order to carbonate a brew in it, you'll need to maintain the temps, and pressure for at least two weeks. Unless you plan to carbonate in a normal keg and then ruin the brew by putting it into the cooler (outside of the keg)...

Sometimes people try to be so clever, they're just plain dumb. Here's your sign...

You're right, trying to find a use for something I have no use for is dumb. Nobody ever came up with a good idea ever. And it's not like one of these would ever fit in my temp controlled chest freezer, it's far too big.

*******.

Eeeesaaassssy fellas!

This is easy.

Hey ****ingnuts. If you don't like our responses don't ask for opinions.

I tried to be helpfull. I am truly curious how you plan to seal the lid. You would need a gasket and and a way to hold it down. Not saying its not possible but a major pain.

if you know so much and are so sure I yourself just do it and report back on how it works. No need to be a *******.

lol, i like how nuckinfuts posted a question but immediately kicked over to trolololol mode.

Anyway - you're not going to be able to use it as intended. The permeability of the rubber seals (both lid and spigot) and even that plastic itself will allow CO2 to escape. You might be able to use it in the very very short term without it being very problematic.

I'd be concerned about the seal around your spigot as well- though you certainly could test that: make yourself a piston that fits tightly into the cooler. fill cooler halfway with water. Put piston on top of water. After calculating the surface area of the water, in inches, apply 5 times that number in weight to the top of the piston. You've just placed 5 PSI onto the liquid. If your spigot holds, you're likely okay. I expect you will see seeping around the edges and even right out the spout of your spigot.

you could sell the cooler and get a corny keg to serve. the miller party pigs can be reused as well as previously mentioned.

an easier way of testing pressure is to attach the quality valve in place of the spigot as you said; then just attach to a compressor with a psi gauge and pressure it up. I bet you can easily get ten lb. but it will leak like a sieve until you figure out how to seal the lid.

Dangerous? not really.

At no point in time did i insult or attack you in any way. I appreciated your reply, I just disagreed about the lid. You can seal them really well.

See now THIS is what I was looking for. Thank you.

Thats a good idea, thank you
