EVABarrier Double Wall Draft Tubing - 4 mm ID x 8 mm OD

EVABarrier Double Wall Draft Tubing - 4 mm ID x 8 mm OD

Please select from the following option(s) to see pricing and availability.

If you're looking for a high-quality draft tubing to take your system into the 21st century, EVABarrier is the clear choice. This double walled tubing offers superior protection against oxidation, CO2 loss and microbial growth. Plus, it's BPA and PVC free! EVA tubing is the future of draft line for professional applications, and now you can rig up your home system with the same first-class tubing.
The 4 mm (5/32") ID size is perfect for homebrew draft applications where only a short beer line is needed. We recommend using 5-6 ft. per line for adequate flow resistance.
Outer Barrier
The outer barrier is made from EVA material and provides a decent stiffness to the tubing while still remaining pliable. This not only makes EVABarrier extremely kink resistant, it also makes it the best tubing to be used with Duotight, John Guest, and other push-in fittings.
Inner Barrier
The inner barrier is made from a proprietary polymer that acts as an excellent gas barrier. You can rest assured that your beer will be better protected from oxygen exposure, as well as CO2 loss. Your beer will stay fresher for longer and not loose carbonation like with other draft line.  With other beverage line, you may notice that beer sitting in the line for an extended period will start to taste flat and/or oxidized.  EVA Barrier tubing is unquestionably better in this regard and you will notice a significantly improved freshness of your beer, especially if it's been sitting in the lines for a while.
Due to the high density and smooth nature of the EVABarrier inner wall, the internal surface of the tubing is remarkably smooth and almost completely impermeable.  This makes it difficult for bacteria and other microbes to attach to the inside surface of the tubing. Just another way EVABarrier is looking out for you and your beer!
  • Inner Diameter - 4 mm (5/32")
  • Outer Diameter - 8 mm (5/16")
  • PVC, BPA , and Plasticizer Free*
  • Outer wall prevents oxidation and CO2 loss
  • Smooth inner wall prevents microbial growth build-up

*EVABarrier does not contain plasticizers, or phthalates, that are used to make PVC flexible. These plasticizers are known to leach out into the beer over time and have adverse health effects.

Does this fit on 1/4" barbs that ball lock disconnects frequently come in?
Trevor Mack on Jul 29, 2019
BEST ANSWER: The 4 mm ID tubing will be too small. The 5 mm will fit, though it will be very snug.

What is the restriction amount on this size and type of tubing?
Robert Zimmer on Apr 29, 2019
BEST ANSWER: Hi Robert - Take a look at this link: https://www.kegworks.com/blog/determine-right-pressure-for-your-draft-beer-system/

4mm x 8mm = 5/32" x 5/16"
Can you connect this 4mm ID tubing to a 3/16" tailpiece? I would like to use this as beer line with my intertap faucets, replacing my current 3/16" beer line. Thanks.
Valued C on Apr 23, 2019
BEST ANSWER: Hi Larry - the 4mm tubing is only 1/16" smaller than 3/16" so if you heat up the end of the tubing before installing, there shouldn't be a problem.
How do you clean EVA line? Is BLC safe?
Andrew Wayland on Jun 6, 2019
BEST ANSWER: Hi Andrew - We recommend cleaning the beer line as you would with any other tubing.
What psi (approximate) should I set my psi to for these lines? I know with a smaller diameter line you would want a lower serving psi to avoid foaming.
Michael Mascianica on Sep 3, 2020
BEST ANSWER: I think of this differently. I adjust the length of the beer line and keep the pressure set to one that is appropriate to the level of carbonation I want. For my old beer line (3/16 I believe), 10 feet worked well, but with the 4mm EVA tubing, I run only 6ft. Works well for me.
Hi. Is this recommended for wine, cider and nitro coffee? Thank you
Marco Jefe on Jul 11, 2020
BEST ANSWER: Should work fine for any of those products.
The wine and the coffee could possibly leave residue though - might not be able to use those lines for other products later.
Can I use this size 4mm ID x 8mm OD for both the gas and beer lines?
Christopher Woodley on Jul 27, 2021
BEST ANSWER: Certainly. Many folks I know have done exactly that. I went with 4mm for beer and 5mm ID for gas only because it's a bit easier to slide onto the barbs of my 1:8 manifold that I didn't want to replace with an MFL version.
What is the recommended inner diameter shank bore for this tubing? 3/16? 1/4? Does it matter?
Jeffrey Hasterok on Oct 6, 2020
BEST ANSWER: 3/16" is closer, but the EVA tubing is very stiff. Better off to use an adapter like this:
Any suggestions for line length for seltzer water? Probably about 30 psi @ 38-40*F. I'm SWAGing about 15 feet, but have no idea really.
jeff royster on Sep 14, 2019
BEST ANSWER: While both of the answers discussing foaming are correct, as far as that goes, you still want to consider your dispense speed - a flow rate of about one pint per second is gotten by having about one psig residual after all restrictions are taken into account. The restriction on this stuff is about 2.9 psig per foot.
30 psig - 1 for serve speed=29 psig; .5 psig for shank and faucet (typically) 28.5; .5 psig for every foot from center of keg to tap - for me that's about 2-3 feet, so, 1-1.5 psig =27 psig / 2.9 = 9.31ft and a bit.
