Aeroflow Reinforced Clear PVC Breather Hose, 5/8″ (16mm) I.D – 1 Metre Length

SKU: AF315-015-1M

Perfect for custom catch can setups, coolant overflows, and breather systems where fluid or vapour visibility is essential. Aeroflow’s heavy-duty Transparent PVC Breather Hose allows you to see exactly what is going on inside your lines, making system monitoring and diagnostics incredibly simple.

Unlike standard silicone or rubber hoses that can suck shut under vacuum, this premium PVC hose is engineered with an embedded steel wire core. This rigid reinforcement prevents kinking, crushing, and collapsing, even when routed through tight bends in cramped engine bays.

With a 5/8″ (15.8mm/16mm) internal diameter, this hose pairs perfectly with Aeroflow -10 push-lock barbs or -12AN cutter-style hose ends, making it a versatile choice for custom plumbing on track, drift, and fast-road builds.

Important Note: This hose is designed for breather, overflow, and water applications only. It is not suitable for fuel systems. Supplied as a pre-cut 1-metre clamshell package.
