The Only BA-Approved Beer Line for Long Draw Trunk Bundles
If you're building or servicing a long draw system, barrier tubing isn't optional — it's the standard. The Brewers Association mandates barrier-lined beer tubing for any run over 25 feet because vinyl simply can't hold up: CO2 permeates out, oxygen permeates in, and the result is flat, oxidized beer before it ever reaches the faucet.
Why Barrier Tubing?
- CO2 retention — the barrier layer prevents carbonation from escaping through the tubing wall over long runs
- Oxygen exclusion — blocks O2 ingress that causes staling and off-flavors in sensitive beers
- Flavor-neutral — doesn't impart taste or odor; compatible with all beer styles including lagers, IPAs, and sours
- BA-compliant — meets Brewers Association Draught Beer Quality Manual specifications

Barrier Tubing FAQ
At what run length does barrier tubing become mandatory?
The Brewers Association standard is 25 feet — beyond that, vinyl's CO2 and oxygen permeability causes noticeable flavor and carbonation loss. Under 25 ft, standard vinyl is generally acceptable, though barrier tubing works fine at any length if you'd rather standardize on one material.
Does barrier tubing need different fittings than vinyl?
No — barrier tubing uses the same standard barbed fittings as vinyl beer line, matched to ID size. No special connectors required, which makes it a straightforward swap when upgrading an existing short-run system.
