Match the Inner Diameter (ID) to your fitting or barb size. The ID is the critical measurement — for example, a 1/4" (≈6.35mm) barb needs tubing with an ID of approximately 6mm. The Outer Diameter (OD) determines wall thickness and pressure capacity. A larger OD relative to ID means a thicker wall and generally higher pressure tolerance. When in doubt, size the ID to your fitting and choose a wall thickness appropriate for your pressure requirements.

Quick reference: 1mm ID ≈ 3/64", 5mm ID ≈ 13/64", 10mm ID ≈ 3/8", 16mm ID ≈ 5/8", 25mm ID ≈ 1".

Yes. This tubing is made from food grade silicone that is generally odorless, tasteless, and non-toxic. It is typically suitable for beer brewing transfer lines, milk and dairy hose runs, winemaking siphons, and other food and beverage applications. It does not impart flavor or odor to liquids passing through it, which is a key advantage over standard rubber or PVC hose.

Food grade silicone tubing typically handles temperatures from approximately -60°C (-76°F) to +200°C (+392°F). This makes it suitable for cold keg lines, hot-side wort transfer in brewing, steam cleaning, and autoclaving in most cases. It remains flexible at low temperatures, unlike PVC which can stiffen and crack in cold environments.

Silicone generally offers better UV and ozone resistance than rubber or PVC alternatives. For prolonged direct outdoor UV exposure over many years, consider shielding the tubing or selecting a UV-stabilized variant. In most sheltered outdoor applications — such as greenhouse hydroponics or covered brewing setups — this clear silicone hose performs well without significant degradation.

This tubing is compatible with standard barb fittings, push-to-connect fittings, and hose clamps sized to match the ID and OD of the tubing you select. It works with both metric and imperial barb fittings — simply match the barb diameter to the tubing ID for a secure, leak-resistant connection. Hose clamps are recommended for pressurized applications to prevent the tubing from slipping off the barb.

Use a sharp utility knife or scissors for a clean, square cut. For smaller diameter tubing (under 5mm ID), sharp scissors work well. For larger diameters, a razor blade or dedicated tubing cutter gives the cleanest edge and ensures a proper seal on fittings. Always cut perpendicular to the tube axis to avoid angled cuts that can cause leaks at connections.

Pressure ratings vary by wall thickness and diameter. Thicker-walled, smaller-diameter tubing generally handles higher pressures. For low-pressure gravity-fed transfers, peristaltic pump applications, and standard homebrewing setups, this tubing is typically well-suited. For high-pressure systems or critical industrial applications, please contact us to confirm the specific variant's pressure rating before ordering.
