Yellow Silicone Tube Hose Pipe Food Grade Soft Rubber Flexible Tubing 1mm-31mm

Match the tube's inner diameter (ID) to the outer diameter of your barbed fitting. For a snug, leak-resistant seal, the tube ID should be equal to or very slightly smaller than the fitting barb OD. For example, a 6 mm ID tube typically fits a 6 mm barb fitting. Check the variant selector for the full ID × OD size chart before ordering.

Yes. The tubing is made from food grade silicone rubber, which is odorless, tasteless, and non-toxic. It does not leach plasticizers or impart flavor to liquids, making it suitable for homebrewing, fermentation transfer lines, drinking water systems, and food-processing applications.

The tubing is rated for continuous use from -60 °C to 180 °C (-76 °F to 356 °F). This covers most household and light-industrial applications including sous-vide water baths, steam-adjacent routing (not direct steam), and cold-side refrigeration lines. For sustained exposure above 150 °C, verify your specific application requirements.

Silicone rubber has inherent resistance to UV radiation and ozone, which means it does not crack or harden with prolonged outdoor exposure the way standard rubber or PVC tubing does. It is a practical choice for garden irrigation connections, outdoor aquarium setups, or any application where the tubing is exposed to sunlight.

Silicone tubing is one of the most common materials used in peristaltic pumps because of its flexibility and recovery after repeated compression. Select the ID and wall thickness that matches your pump head's specifications. Thicker-walled variants (larger OD relative to ID) generally offer longer service life under repeated peristaltic action.

The tubing cuts cleanly with a sharp pair of scissors or a utility knife — no saw or pipe cutter required. To install, simply push the tube end onto a barbed fitting. For smaller diameters, briefly warming the tube end in warm water (not boiling) softens the silicone and makes it easier to slide over the barb. No adhesive or clamps are required for low-pressure applications, though hose clamps are recommended for pressurized lines.

Silicone rubber has good resistance to many dilute acids, bases, and common cleaning agents such as isopropyl alcohol and dilute bleach solutions. It is not recommended for use with concentrated solvents, strong oxidizing acids, or hydrocarbon fuels. If your application involves aggressive chemicals, contact us to confirm compatibility before ordering.
