EVABarrier Double Wall Tubing - 4 mm ID x 8 mm OD | Hose for Beer & Gas
€2.31
Upgrade your draft setup with EVABarrier Double Wall Tubing - 4 mm ID x 8 mm OD, the modern standard in beverage line technology. This dual-layer tubing provides exceptional resistance to oxygen ingress, CO₂ loss, and microbial contamination – all while being completely BPA- and PVC-free. Originally designed for professional use, it’s now available for homebrewers seeking top-tier performance.
Optimized for Home Use
The 4 mm (5/32") inner diameter is ideal for short-draw home draft systems. For optimal flow resistance, we recommend using 5–6 feet per line.
Outer Layer – Durable & Duotight-Ready
The outer layer is made from EVA, offering a firm yet flexible structure that resists kinks and works flawlessly with Duotight, John Guest, and similar push-in fittings.
Inner Layer – Sealed for Freshness
The inner barrier uses a high-density polymer that significantly reduces gas permeability. This keeps oxygen out and CO₂ in, meaning your beer stays carbonated, fresh, and crisp even after longer resting times in the lines. Unlike standard beverage tubing, EVABarrier prevents that flat or oxidized taste that can develop with poor-quality lines.
Hygienic by Design
The smooth inner surface is highly resistant to microbial attachment, minimizing buildup and making cleaning easier – a crucial advantage for maintaining quality over time.
Ball Lock Keg Compatible
EVABarrier tubing fits perfectly with Duotight Ball Lock disconnects for direct connection to NC (ball lock) kegs. Just ensure you select the correct disconnects for 8 mm outer diameter tubing.
