Evabarrier Double Wall Draft Tubing - 4 Mm Id X 8 Mm Od is the epitome of high-quality draft tubing, designed to take your homebrew system to the next level. This exceptional tubing boasts superior protection against oxidation, CO2 loss, and microbial growth, making it the perfect choice for beer enthusiasts who demand nothing but the best. What's more, it's BPA and PVC free, ensuring a safer and healthier brewing experience.

The 4 mm (5/32") ID size is specifically designed for homebrew draft applications where short beer lines are necessary. We recommend using 5-6 ft. per line for optimal flow resistance, ensuring your beer flows smoothly and consistently. The outer barrier is crafted from EVA material, providing an ideal combination of stiffness and pliability. This unique blend of properties makes EVABarrier extremely kink-resistant and perfect for use with John Guest and other push-in fittings.

The inner barrier is composed of a proprietary polymer that acts as an excellent gas barrier, safeguarding your beer from oxygen exposure and CO2 loss. Unlike other draft lines, EVABarrier ensures your beer remains fresh and carbonated for longer, eliminating the risk of flat or oxidized flavors. This is particularly noticeable when beer sits in the lines for an extended period. The high-density, smooth inner surface of the tubing prevents bacteria and other microbes from attaching, ensuring a cleaner and healthier brewing experience.

What sets EVABarrier apart is its seamless compatibility with Duotight Ball Lock QDs, allowing 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). With EVABarrier, you can trust that your beer will flow smoothly and consistently, every time.

This exceptional tubing boasts an impressive array of features, including its PVC, BPA, and plasticizer-free construction. The stiff outer wall is kink-resistant and easy to use with Duotight fittings, while the smooth inner wall prevents oxidation, CO2 loss, and microbial growth. With EVABarrier, you can have complete confidence in the quality and safety of your brewing experience.

With its unmatched protection against oxidation, CO2 loss, and microbial growth, this exceptional tubing ensures your beer tastes fresher, cleaner, and more delicious than ever before.
