Food Grade Silicone Tubing 5mm–10mm ID — Flexible High-Temp Rubber Hose

Match the ID (inner diameter) to the outer diameter of the fitting or barb it will slip over. For example, a 6mm barb fitting typically requires 6mm ID tubing. The OD determines wall thickness — a larger OD relative to ID means a thicker, more pressure-resistant wall. Common conversions: 5mm ID ≈ 3/16", 6mm ID ≈ 1/4", 8mm ID ≈ 5/16", 10mm ID ≈ 3/8". If you're between sizes, generally size down for a snug, leak-resistant fit.

This type of silicone tubing can typically handle low-to-moderate pressures, generally up to 30–60 PSI depending on wall thickness and diameter. Thicker-walled variants (larger OD relative to ID, such as 6mm×10mm) generally support higher pressures than thin-walled variants (such as 5mm×6mm). For high-pressure applications, please contact us to confirm suitability before ordering.

Silicone is generally more UV and ozone resistant than standard rubber or PVC tubing, making it suitable for outdoor use in most cases. Prolonged direct UV exposure over many years may cause minor surface degradation. For permanent outdoor installations, shielding the tubing from direct sunlight is recommended to maximize service life.

This food-grade silicone tubing is typically rated for continuous use from approximately -60°C to +200°C (-76°F to +392°F). This makes it suitable for both cold applications (refrigeration lines, cold brew) and high-temperature uses such as brewing, autoclaving, and engine coolant overflow lines.

Yes. The ID sizes (5mm, 6mm, 7mm, 8mm, 9mm, 10mm) are designed to fit standard metric barb fittings. For imperial fittings: 6mm ID ≈ 1/4", 8mm ID ≈ 5/16", 10mm ID ≈ 3/8". Always verify the barb OD matches the tubing ID for a secure, leak-free connection. Hose clamps can be used for added security on pressurized lines.

Yes. This tubing is made from food-grade silicone, which is non-toxic, odorless, and BPA-free. It is commonly used in homebrewing, winemaking, aquariums, peristaltic pumps, and food processing lines. It does not impart taste or odor to liquids passing through it, and can be sterilized with boiling water or steam in most cases.

Color is purely aesthetic and does not affect the tubing's performance, temperature rating, or food-grade properties. The High Transparency option is popular for applications where you need to visually monitor flow. Colored variants are useful for color-coding different fluid lines in complex setups — for example, using red for hot lines and blue for cold in a brewing or lab environment.
