Food Grade Silicone Tubing — Flexible, Heat-Resistant Rubber Hose for DIY, Brewing & Lab Use

Whether you're routing coolant lines in a homebrewing setup, replacing cracked vinyl hose in a garden irrigation system, or building a custom aquarium sump, finding flexible tubing that won't kink, crack, or leach chemicals into your liquid is a constant challenge. Standard PVC and rubber hoses harden over time, develop odors, and fail at temperature extremes — leaving DIYers and hobbyists hunting for a better solution.

This food grade silicone tubing is available in five Inner Diameter (ID) × Outer Diameter (OD) combinations — 2mm×4mm (≈5/64"×5/32"), 3mm×5mm (≈1/8"×13/64"), 4mm×6mm (≈5/32"×15/64"), 5mm×7mm (≈13/64"×9/32"), and 6mm×8mm (≈15/64"×5/16") — with a consistent 1mm wall thickness throughout. Each piece is cut from a continuous silicone extrusion and is available in lengths of 1M, 2M, 3M, 5M, and 10M so you can order exactly what your project requires.

Typical applications include homebrewing and winemaking transfer lines, aquarium and pond pump connections, laboratory fluid handling, peristaltic pump tubing, CPAP humidifier hose replacement, and low-pressure air or gas routing in workshop equipment. The flexible silicone rubber construction makes it easy to route around tight bends without kinking — a common pain point with rigid plastic tubing.

ℹ️ Compatibility Note: This tubing uses slip-fit connections. Match the tube's Inner Diameter (ID) to the outer diameter of your barbed fitting or hose barb for a secure, leak-resistant seal. A hose clamp is recommended for pressurized lines.

✅ Key Features of These Food Grade Silicone Tubes

🌡️Wide Temperature Range — Rated from -60°C to 180°C (-76°F to 356°F), this flexible silicone hose handles both freezer-cold and near-boiling applications without hardening or cracking.
🍺Food-Safe & Odor-Free — Made from food grade silicone rubber that is non-toxic, tasteless, and odorless — safe for homebrewing transfer lines, winemaking siphons, and drinking water systems.
🔄Kink-Resistant Flexibility — The soft silicone wall flexes around tight corners and bends without collapsing, making it ideal for routing flexible rubber tubing through confined spaces in DIY builds.
✂️Cut-to-Length Convenience — Available in 1M through 10M lengths; cuts cleanly with scissors or a utility knife so you get exactly the silicone tube length your project needs with no waste.
🛡️UV & Ozone Resistant — Silicone resists UV degradation and ozone attack better than standard vinyl or latex tubing, making it a longer-lasting choice for outdoor irrigation and garden hose applications.
⚙️Consistent 1mm Wall Thickness — Uniform wall construction across all five diameter options ensures predictable fit on barbed fittings and reliable performance in peristaltic pump and laboratory tubing setups.

⚠️ Sizing Tip: Not sure which ID to order? Measure the outer diameter of your barb or fitting — that measurement should match the tube's Inner Diameter for a snug slip-fit connection. Contact us if you need help confirming compatibility.

❓ Frequently Asked Questions

How do I choose the right silicone tube size?

Match the Inner Diameter (ID) to the outer diameter of the fitting or barb it will slip over. For example, a 1/4" (6.35mm) barb typically works best with a 6mm ID tube. The wall thickness on these tubes is generally 1mm, so the OD will be ID + 2mm. When in doubt, size up — silicone stretches slightly for a snug seal.

What temperature range can this silicone tubing handle?

This tubing is rated for continuous use from -60°C to 180°C (-76°F to 356°F). It generally handles brief steam exposure and is suitable for most hot-water, brewing, and low-pressure steam applications.

Is this tubing safe for food and beverage contact?

Yes. The tubing is made from food-grade silicone, which is odorless, tasteless, and non-toxic. It is commonly used in homebrewing, winemaking, aquariums, and food processing lines where contact with liquids or gases is required.

Can I use this silicone hose outdoors or in UV-exposed environments?

Silicone generally offers good UV and ozone resistance compared to standard rubber or PVC tubing. For long-term outdoor exposure, it is typically more durable than vinyl alternatives, though shielding from direct sunlight is still recommended for maximum service life.

What fittings or connectors are compatible with this tubing?

This tubing uses a slip-fit connection — no threads required. It is compatible with standard barbed fittings, hose barbs, and push-fit connectors sized to match the ID. For a secure seal, use a hose clamp or zip tie over the barb.

How do I cut the tubing to the length I need?

The tubing can be cut cleanly with sharp scissors or a utility knife. It is sold in lengths of 1M, 2M, 3M, 5M, and 10M so you can order the closest length to your project needs and trim to fit on-site.

What is the working pressure of this silicone tubing?

Working pressure varies by diameter and wall thickness. For these sizes (1mm wall), the tubing is generally suitable for low-pressure applications — typically up to 30–60 PSI depending on temperature. For high-pressure lines, please contact us to confirm suitability.
