EVABarrier Double Wall Draft Tubing - 6.3 mm ID x 9.5 mm OD

EVABarrier Double Wall Draft Tubing - 6.3 mm ID x 9.5 mm OD

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

EVABarrier double wall tubing is an excellent choice for all draft dispensing applications. The inner barrier is an excellent gas barrier, keeping oxygen out and CO2 in. The inner wall is also extremely smooth to prevent bacteria and other microbes from attaching to the inside surface. The outer barrier gives the tubing a decent stiffness while still remaining pliable. This makes EVA Barrier remarkably kink resistant and the perfect choice for use with Duotight, John Guest, and other push-in fittings.

The 6.3 mm (1/4") ID size is recommended to be used as gas line or long draw beverage lines. If you intend to use it as beverage line, we recommend using 20-25 ft. per line for adequate flow resistance.

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 - 6.3 mm (1/4")
  • Outer Diameter - 9.5 mm (3/8")
  • 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.

Kegland Part number: KL06248

What's the resistance of this tube for calculating serving pressure in long draw system (psi / ft)?
Lutz Engmann on Jun 27, 2022
Is there a benefit to going with the 6.3 mm (1/4") ID size for my co2 lines over using an 8mm OD line? I'm currently using the smaller line to serve and keeping the connectors the same would be a bonus if possible.
JOHN PEREA on May 9, 2023
BEST ANSWER: I haven't tried this but it should work. The inside of my kegerator is not as tidy as it could be. Having a thicker line helps me identify the gas line quickly when necessary. Unless I'm missing something it should be a personal preference issue.
Will this slide and seal on a barbed fitting?
John Hall on Feb 22, 2022
BEST ANSWER: Yes, this fit 1/4” barbs
Will this work as an immersion chiller line? Will it withstand the temperatures?
Ray Gilmore on Jan 14, 2024
BEST ANSWER: The tubing inner diameter is too narrow to effectively be used for chilling. This is more a cold line tubing that works great for kegerators or fermenters. It will decrease your chiller wort transfer speed

Works perfectly
I have this for my glycol chiller and it works perfectly for that. Thick tubing that doesn't kink or bend, but enough flex to make it to the cooling coil

Great draft tubing
Excellent tubing! I like the simplicity of the duotight and it works perfect! Very easy to install - I switched to Eva tubing for both gas and liquid and it was an excellent choice!

Totally tubular
Looks to be good quality tube. Works well with the 3/16" barb fitting on my tap handle fitting. I used it with a Duotight fitting on the other end. Duotight fittings are definitely the way to go. Barb fittings and hose clamps need to go.
