Adding beerline resistance inside the keg.

**Bobby_M** · 12-13-2008, 06:46 PM

I've seen the DIY where you put the innards of an epoxy mixing tip inline with your beerline to add enough resistance so you didn't need 10' of line for balance. I just had a little lightbulb over the head moment that I'd like to discuss.

First, everyone knows that the resistance doesn't have to occur outside the keg right? Like if you could turn your dip tube into a 10' length of 3/16" ID crazy straw and put the faucet right on the QD, it would pour slow.

The inside diameter of dip tubes seem to be 1/4" and it's large enough to effectively add no resistance. What if you got that down to 1/8" ID? A 20" section of 1/16" wall Polyethylene shoved down inside the diptube might be able to shorten the serving line by a few feet. Is the sudden change from 1/8" to 3/16" going to be a problem?

While I am certainly no expert, I would think that you would create a venturi effect going into the larger line.

try it with a piece of silicone airline tubing. tie some thread on a toothpick and drop it through. then tie your tubing to it and lube the bejezus out of it and pull it through.

then try different shortened line lenghts and see how much you can loose.

I think it'd be perfect for a 3 gallon travel keg setup.

Maybe one could just put the epoxy mixing innards into the dip tube itself. I've got two sizes of innards at home. I'll see if I can find time in the next couple of days to see if one will fit inside.

All good ideas. I actually already have some bev grade PVC 1/8" ID x 1/4"OD. I'll do the comparison when I can and report back.

Foxx equipment sells a flow restrictor intended to be inserted in the shank behind the faucet that might work. Bottom left of page 109 Looks like there are 4 different restrictions available for 1/4" diameter. I don't remember what the cost was on them from the last time I had the wholesale catalog in my hands.

Anyone any closer on this? I have a vested interest in your results. Either the inside line or the flow restrictor.

For my travel keg setups, I just drop the dispensing pressure to 2 PSI. It's just gently pushing the beer out. Then again, this only works for when you expect to consume the keg in a few hours. Then again, if you don't, you can always crank it back up to 12 PSI to recover any lost carbonation for what remains.

I've heard of people just adding the extra beer line to the bottom of the dip tube and coiling the 10' or so of tubing inside the keg. That way the resistance is inside the keg and you can run a faucet right off the keg. I've never tried it.

It would definitely work from a theoretical perspective but the opening the coil will represent the lowest level of beer you could drain too. You'd have to sanitize the whole thing length inside and out and it would displace a good amount of beer too. I'm going to experiment with 1/8" ID tubing in the diptube.
