Food Grade Silicone Tubing 3mm ID x 6mm OD — Clear Flexible Hose for Beer, Milk & Liquid Transfer

Measure the distance between your inlet and outlet, then add at least 10–15% extra for routing around obstacles or making clean bends. For most homebrewing setups, 1 metre (≈39") covers short runs between a fermenter tap and a receiving vessel, while 3–5 metres suits longer transfer lines or multi-vessel systems. When in doubt, size up — silicone trims cleanly with scissors.

This tubing has an inner diameter (ID) of 3mm (≈1/8") and an outer diameter (OD) of 6mm (≈1/4"), giving a wall thickness of approximately 1.5mm. Always verify your fitting's barb outer diameter matches the 3mm ID before ordering to ensure a snug, leak-free fit.

Yes. This tubing is made from food-grade silicone, which is generally recognized as safe for contact with food, beverages, and dairy products. It is odor-free and does not impart taste or color to liquids passing through it — a key requirement for beer, wine, and milk transfer applications.

Food-grade silicone tubing of this type typically withstands temperatures from approximately -60°C to +200°C (-76°F to +392°F). This makes it suitable for cold liquid transfer as well as hot-water rinsing and steam sanitizing in most hobby and light commercial applications. Confirm your specific requirements before exposing to extreme or sustained high-heat conditions.

Silicone generally offers better UV and ozone resistance than standard rubber hoses, making it suitable for occasional outdoor use or workshop environments with indirect sunlight. For prolonged direct UV exposure, consider shielding the tubing with a sleeve or routing it through conduit to extend its service life.

This tubing is compatible with barbed fittings sized for a 3mm (1/8") bore. It typically fits standard 1/8" barb connectors used in homebrewing equipment, aquarium CO₂ systems, and laboratory tubing setups. Always check the barb OD against the tube ID for a secure, leak-free connection — a barb that is slightly larger than the ID will create a tighter grip.

Rinse with warm water immediately after use to prevent residue buildup. For deeper cleaning, flush with a food-safe sanitizer or a diluted no-rinse sanitizer solution. Silicone can generally be autoclaved or boiled for sterilization. Note that repeated high-heat cycles may gradually affect flexibility over time, so inspect the tubing periodically for any signs of stiffening or surface degradation.
