Hey folks, now that I've been fermenting in a keg for a while (not myself, my beer) I'm thinking a pressure relief valve would help to keep the brew at the pressure that'll keep it carbed once it's done. Anyway, I know this has been covered but I could not find the posts I was looking for with a search (yes, I'm inept... or just lazy). How many of you have build a pressure relief valve, how did you do it and what does it look like? Thanks!

I actually pursued this and bought this item:

Harbor Freight Tools - Quality Tools at the Lowest Prices

Or grainger item

Pneumatics & Hydraulics > Air Compressor Accessories > Compressor Valves > Valve,Pressure Relief : Grainger Industrial Supply


The harbor freight air regulator needs to be disassembled and cleaned well to remove all the air tool oil. I lubed it up with keg lube after word and tested it out. Seems to work but time will tell.

I really like the one from harbor freight!

It looks like it gives you a bit more control

I've played with it quite a bit and it seems to be well made. It has a tiny little pin in the side that keeps the handle from backing off all the way so you just have to slide a blade in and work the pin out and then the handle will come off.

There is a big spring and a tight fitting gasket and another part in there.

Send a PM to wortmonger or search "closed system fermentation". He's something of a spunding jedi.

Neat idea. Couldn't you use a barbed gas connect with a hose on it submerged in water like a mini blow off?

Looks like it would work fine to me. You'd still need to take the poppet out of course. You could even cut a SHORT piece of tubing and put one end on the gas connect and just slide the airlock into the other end. Again, the poppet would need to be removed.

I'm not worried about a blow off. I've done that. What I want is precise control of the pressure so I can just counter-flow it to a keg and it'll be naturally carbed.
