Food Safe Silicone Rubber Tubing — Translucent Hose for Beer, Wine & Milk (ID 2–38mm)

Match the inner diameter (ID) to your fitting or barb size. For example, a 1/4" barb fitting typically requires a 6mm (≈0.24") ID tube. The outer diameter determines wall thickness — a larger OD with the same ID means a thicker, more pressure-resistant wall. Common inch-to-mm conversions: 1/4" ≈ 6mm, 5/16" ≈ 8mm, 3/8" ≈ 10mm, 1/2" ≈ 12mm, 5/8" ≈ 16mm, 3/4" ≈ 19mm, 1" ≈ 25mm. When in doubt, measure your fitting's outer diameter and select a tube ID that is equal to or slightly smaller for a snug, leak-free fit.

Food-grade silicone tubing of this type can generally handle low-to-moderate pressures, typically up to 30–60 PSI depending on wall thickness and diameter. Thicker-walled variants (larger OD relative to ID) offer greater pressure resistance. For high-pressure applications, please contact us to confirm the specific variant's rating.

Yes. Silicone rubber is generally rated for continuous use from approximately -60°C (-76°F) to +200°C (+392°F), making it suitable for outdoor use, steam cleaning, and hot-liquid transfer. UV and ozone resistance is also generally good, though prolonged direct sunlight exposure over many years may cause minor surface degradation.

This tubing is made from food-grade silicone rubber, which is non-toxic, odorless, and tasteless. It will not impart flavors or odors to beer, wine, milk, or other food-grade liquids — a critical requirement for homebrewing and dairy applications.

The tubing is sized in metric millimeters (ID × OD). It is generally compatible with standard barb fittings, hose clamps, and push-fit connectors sized to match the inner diameter. For US standard fittings, use the inch conversion (e.g., 6mm ID ≈ 1/4", 8mm ID ≈ 5/16", 10mm ID ≈ 3/8"). Always verify your fitting's barb OD matches the tube ID for a secure seal.

A larger outer diameter with the same inner diameter means a thicker wall, which provides more rigidity, better kink resistance, and higher pressure tolerance. A thinner wall (smaller OD for the same ID) is more flexible and easier to route through tight spaces. Choose thicker walls for pressurized transfer lines and thinner walls for gravity-fed or low-pressure siphoning.

Silicone tubing is generally not recommended as a primary CO2 gas line because silicone is slightly gas-permeable, which can lead to slow CO2 loss over time. For liquid transfer of carbonated beverages at low pressure, it is generally acceptable for short runs. For dedicated CO2 supply lines, a vinyl or polyurethane tubing is typically preferred.
