New idea to identify beer/tap lines

[Skeeter686]

I think I'm going to hate the answer but here goes...

I'm planning to move my keezer from the "beer room" (a small walk-in-pantry-like room off the kitchen) to the closet on the opposite side of one of the beer room's walls. The plan is to put faucets on a box mounted to the common wall, with a trunk line running the short distance from the keezer to the box (i.e., through the wall).

Currently, the faucets are mounted through the collar on the keezer and I don't have problems with off flavors or poor pours. With the new configuration, I'm wondering if it would be prudent to migrate from my vinyl beer lines to EVABarrier.

I assume this would require replacement of:

• Lines
• Shank tail pieces
• Ball lock connectors

I just recently upgraded all my ball locks to CM Becker, so it'll be annoying to have to upgrade again.

I should probably not be thread jacking, although it feels like it's too late for that already.

Yes EVA barrier lines will make a difference.

The 2mm internal lines are very short and low volume of beer to oxidis so not much to " waste ".

fwiw, I dispense 3 volume beers at ~1 ounce per second using 9 feet of 4mm ID EVABarrier tubing through a standard Perlick 525SS

I have 5-6ft lines on all my taps except one and that had all the leftover. I'll measure it today, but I thought it was over 10. Didn't seem to make any difference on my high co2 pours. I'll recheck everything today. That's exactly why I left it long, but it did seem to work.

I use the same system - 5 CO2 lines at 7', and one is about 15' that I use to purge kegs of O2 after cleaning, and fill with CO2. No issues about length on the gas lines - it is more about beer lines I think.

Never thought of just reducing down from 8mm to 4mm (od). I was looking for the QD/shank screw fittings. Amazon sells the step downs and 2mm id PTFE tubing. The PTFE looks to be foodgrade but is O2 permeable. Guess that's no different from the days of using the old style beer lines. I'm just looking for a solution to get highly carbonated styles out of the keg without a glass of foam.

and my FWIW: I use 37" of the 3mm ID EVABarrier, nice and short and no O2 issues. Rather than look everywhere for push-fittings that weren't available at the time, I just swaged them onto 1/4" swivel nuts. It's really easy to do..might suit your need.

Sorry, I was referring to the dispensing side. The "high co2 pour" should have been high carb beers.

I swagged everything on my 4mm tubing except for some of the QD's, those were cheap enough. Thought/believe the 2mm id would probably be way too tight.

 

[DuncB]

The 2mm internal only has 1mm walls so they would be very thin once swaged onto a 4mm. I wouldn't trust that join.

I bought colored silicone bands to tell the lines apart. To avoid mold build up.

You don't have to! I love my CM Beckers and will never use anything else. Back when @KegLand gifted us with EVABarrier/duotight they had not yet begun producing duotight disconnects and were still making faux-CMBs with the 1/4"MFLs and so we have this adapter:

Alternatively you can easily swag EVABarrier onto swivel-nuts; https://www.homebrewtalk.com/thread...mm-monotight-connector-duotight-shank.730515/
I did it with the 3mmID..4mm would be easier. Your larger issue to deal with will be keeping your trunk line cool and of course in the spirit of this thread: Labelling the lines in your trunk...not thread-jacking!
