Food Grade Silicone Rubber Tubing — Flexible, Heat-Resistant Hose for Brewing, Aquarium & Fluid Transfer

Whether you're building a homebrewing setup, routing aquarium lines, or transferring milk and other food-safe liquids, finding tubing that won't leach odors, crack under heat, or kink mid-transfer is a constant challenge. Standard PVC and rubber hoses often fall short — they stiffen in cold, soften unevenly in heat, and can impart off-flavors to sensitive liquids.

This food-grade silicone rubber tubing is available in three cross-section sizes — 2x3mm (ID 2mm / OD 3mm, ≈5/64" ID), 3x4mm (ID 3mm / OD 4mm, ≈1/8" ID), and 3x5mm (ID 3mm / OD 5mm, ≈1/8" ID with thicker wall) — and in lengths from 1 meter up to 50 meters. Colors include Transparent, Black, Red, White, Yellow, Dark Blue, Green, Sky Blue, Transparent Red, Orange Red, Pink, Purple, and Orange, making it easy to color-code fluid lines in complex setups.

Typical use cases include homebrewing beer and wine transfer lines, aquarium and fish tank air/water tubing, peristaltic pump tubing for dairy or beverage dispensing, laboratory fluid routing, and general DIY fluid-handling projects where a flexible, food-safe silicone hose is required.

🔗 Compatibility Note: Match the inner diameter (ID) to your barb fitting size. 2x3mm fits 2mm barbs; 3x4mm and 3x5mm fit standard 3mm barbs. Check your pump or fitting spec before ordering.

✅ Key Features of These Food Grade Silicone Rubber Tubes

🧪Food-Safe Silicone Material — Made from food-grade silicone rubber that is odor-free, taste-neutral, and non-toxic, making it suitable for direct contact with beer, wine, milk, and other consumable liquids.
🌡️Wide Temperature Tolerance — Silicone rubber typically handles temperatures from -60°C to 200°C (-76°F to 392°F), allowing use in both hot-side brewing transfers and cold-side chilling applications without cracking or deforming.
🎨13 Color Options for Line Identification — Available in Transparent, Black, Red, White, Yellow, Dark Blue, Green, Sky Blue, Transparent Red, Orange Red, Pink, Purple, and Orange — ideal for color-coding multiple fluid lines in brewing or aquarium systems.
📏Three Cross-Section Sizes — Choose from 2x3mm, 3x4mm, or 3x5mm to match your specific barb fitting or pump port, with the 3x5mm offering a thicker wall for applications requiring added durability.
🔄Flexible & Kink-Resistant Construction — Silicone tubing remains pliable across a wide temperature range, resisting kinking during routing around corners or through tight spaces in brewing rigs and aquarium cabinets.
✂️Cut-to-Length Rolls (1–50 Meters) — Available in seven roll lengths (1, 3, 5, 10, 20, 25, and 50 meters), so you can order exactly what your project needs and cut to any custom length with standard scissors or a utility knife.

⚠️ Size Tip: If you are unsure which size fits your pump or fitting, measure the barb OD and select the tubing ID that matches or is 0.5–1mm smaller for a snug, leak-resistant fit.

❓ Frequently Asked Questions

How do I choose the right size silicone tubing?

Match the inner diameter (ID) to your fitting or barb size. For example, a 3mm barb fitting typically requires 3×4mm or 3×5mm tubing. If you need a snug seal, choose an ID equal to or slightly smaller than the barb OD. Sizes here range from 2mm ID (≈5/64") to 3mm ID (≈1/8"). When in doubt, go with the 3×5mm for a thicker wall and more secure clamp grip.

What temperature range can this silicone tubing handle?

Food-grade silicone tubing generally withstands temperatures from approximately -60°C (-76°F) to 200°C (392°F). This makes it suitable for hot-side brewing transfers, sterilization with boiling water, and cold-side chilling applications. In most cases, it will not crack, stiffen, or deform within this range.

Is this tubing safe for beer, wine, milk, and other food contact?

Yes. This tubing is made from food-grade silicone rubber, which is odor-free, taste-neutral, and non-toxic. It is commonly used in homebrewing, winemaking, dairy transfer, aquarium systems, and laboratory fluid routing. It will not impart off-flavors to beer, wine, or other sensitive liquids.

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

Silicone rubber generally offers better UV and ozone resistance than standard rubber or PVC tubing. For prolonged outdoor UV exposure, shielding the tubing or routing it through conduit is recommended to extend service life. In most indoor and semi-outdoor applications, it performs well without additional protection.

What fittings and connectors are compatible with this tubing?

This tubing is compatible with standard barb fittings matching the inner diameter. For 2×3mm tubing, use 2mm barbs; for 3×4mm or 3×5mm, use 3mm barbs. Hose clamps can be used for a more secure connection on pressurized or high-flow applications. The tubing is also compatible with most peristaltic pump heads designed for silicone tubing in the 2–3mm ID range.

How do I clean and sanitize silicone tubing between uses?

Silicone tubing can typically be cleaned with hot water, mild detergent, or standard brewing sanitizers such as Star San or iodophor. It is generally autoclavable and can withstand repeated sterilization cycles. Rinse thoroughly after sanitizing before use with food or beverage liquids.

Can I cut this tubing to a custom length?

Yes. The tubing is sold by the meter and can be cut to any length with scissors or a utility knife. Choose the roll length that best fits your project — 1m for short runs, up to 50m for large installations — to minimize waste and avoid unnecessary joins.
