Clear Silicone Tubing — Food Grade Flexible Rubber Hose for Beer, Water & Medical Use | 0.3–50mm ID

Match the ID to the outer diameter of the fitting or barb it will slip over. For example, a 6mm (≈1/4") barb fitting typically requires a 6mm ID tube. When in doubt, size down slightly — silicone stretches, so a snug fit generally seals better than a loose one. For micro-bore applications like capillary or peristaltic pump tubing, measure your pump head's rotor channel width to confirm compatibility.

Wall thickness equals (OD − ID) ÷ 2. For example, a 6mm ID × 10mm OD tube has a 2mm wall. Thicker walls generally handle higher pressure and provide more structural rigidity, while thinner walls are more flexible and better suited for peristaltic pumps where the tube must compress and recover repeatedly.

Yes. These tubes are made from food-grade silicone rubber that is odorless, tasteless, and non-toxic. They are commonly used for homebrewing beer, wine, kombucha, and other food/beverage transfer applications. Silicone does not impart flavors or leach plasticizers into liquids the way PVC tubing can.

Silicone rubber typically withstands temperatures from approximately −60°C (−76°F) to +200°C (+392°F). This makes it suitable for both cold-side fermentation lines and hot-side wort transfer in brewing, as well as autoclaving and general industrial use. For high-pressure steam applications, contact us to confirm the specific variant's rating.

Silicone has good UV and ozone resistance compared to standard rubber, making it generally suitable for outdoor use. However, prolonged direct UV exposure over many years may cause gradual surface degradation. For long-term outdoor installations, consider shielding the tubing from direct sunlight where possible.

These tubes are compatible with standard barb fittings, hose clamps, and push-fit connectors sized to match the tube's ID. They work with brass, stainless steel, and food-safe plastic fittings. Always verify the barb OD matches your selected tube ID for a leak-free connection. For very small bore sizes (under 1mm ID), confirm fitting compatibility before ordering.

Working pressure varies by wall thickness and tube diameter. Thicker-walled, smaller-bore tubes generally handle higher pressures. For low-pressure gravity-fed or peristaltic pump applications (typically under 30 PSI), most sizes in this range are suitable. For higher-pressure applications, contact us to confirm the specific variant's pressure rating before ordering.

For most homebrewing setups, a 6mm ID (≈1/4") to 10mm ID (≈3/8") tube is commonly used for liquid transfer lines. Match the ID to your tap, pump outlet, or racking cane diameter. A 5m or 10m length is typically sufficient for a standard homebrew setup. For gas lines (CO₂), smaller bore sizes in the 3mm–5mm ID range are generally used.
