EVABarrier Double Wall Draft Tubing - 5 mm ID x 8 mm OD

EVABarrier Double Wall Draft Tubing - 5 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 5 mm (13/64") ID size is perfect for draft applications where a longer beverage line is needed. We recommend using 10-12 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!

Direct Connect to Ball Lock Kegs
This tubing works seamlessly with Duotight Gas In and Bev Out Ball Lock QDs which allow you to connect your draft lines directly to your ball lock homebrew keg. Be sure to select the correct size QD fittings that correspond to your tubing's outer diameter (OD).


  • Inner Diameter - 5 mm (13/64")
  • Outer Diameter - 8 mm (5/16")
  • PVC, BPA , and Plasticizer Free*
  • Stiff outer wall is kink resistant and easy to use with Duotight fittings
  • Smooth inner wall prevents oxidation, CO2 loss and 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.

Would this size be appropriate for a gas line?
Iain W Barkdsale on Apr 25, 2019
BEST ANSWER: Hi Iain - Yes, typically gas lines are 5/16".
What’s the max psi supported?
Juan Castillo on Jul 29, 2022
BEST ANSWER: I seem to remember it being 150 psi, I am serving and carbing at 40 (seltzer) and have no issues.

Best beer line
I use this as gas tubing and the 4mm for beer. 4mm is better than 5/16 because I don't need such long lines. For beer my system uses 4.25 feet of 4mm at 12 lbs pressure. Pours perfect. I would have used the 4mm for gas also, but I needed line to fit over my 1/4" regulator barb. This makes it (barely), if heated/softened in boiling water.

Good gas lines for duotight fittings
It’s gas line for a kegerator, so not much to say about it. Perfect for the duotight fittings, and seals well. They are a bit stiff, due to the double wall, so take that into consideration if you are running the line through cabinets as I did.

Light, flexible, doesn't leak!
I was so hesitant to switch at first because I figured that all the plastic fittings had to make this system inferior and prone to leaks. I'm disappointed it myself for waiting so long to switch! The tubing is easy to cut, easier to connect, and extremely flexible for tight spots. Definitely recommend.

Works perfect for my application. Wanted 2 co2 hoses to come from an externally hung tank and regulator. Both tunes fit through the keterator opening. The quick connect duotight fitting work well.
