Purple Food Grade Silicone Tube Hose — Flexible, Temperature-Resistant Tubing for Home & Lab Use

When a standard rubber hose cracks, stiffens, or leaves an unwanted taste in your fluid lines, it becomes a real problem — whether you're routing water through a home brewing setup, plumbing a fish tank, or sealing a DIY cooling loop. This purple food grade silicone tube hose is built for users who need a flexible, chemically inert conduit that holds up across a wide temperature range without degrading or imparting odors.

Each length is made from food-safe silicone rubber with an inner diameter (ID) ranging from 2mm to 6mm (~0.08" to 0.24") and an outer diameter (OD) from 4mm to 8mm (~0.16" to 0.31"). Wall thickness varies by size from 1mm to 2mm. Available in lengths of 1M, 2M, 3M, 5M, and 10M — sold by the meter so you get exactly what your project requires.

Typical applications include aquarium airline tubing, homebrewing siphon lines, laboratory fluid transfer, peristaltic pump connections, and small-bore coolant routing in electronics enclosures. The soft, flexible silicone tube hose bends without kinking, making it well-suited for tight routing paths in cabinetry or equipment panels.

🔗 Compatibility: Fits standard barbed fittings and push-in connectors sized to match the listed ID. Verify your fitting's barb OD matches the tube ID before ordering. Suitable for water, air, and most non-petroleum fluids.

✅ Key Features of These Food Grade Silicone Tube Hoses

🧪 Food-Safe Silicone Material — Certified food grade silicone rubber; odorless, tasteless, and non-toxic. Safe for contact with drinking water, brewing wort, and food-processing fluids.
🌡️ Wide Temperature Range — Rated from -60°C to 180°C (-76°F to 356°F). Stays pliable in cold environments and resists softening or deformation under sustained heat.
📐 Multiple Size Options — Available in six ID×OD combinations (2×4mm through 6×8mm) and five lengths (1M–10M), letting you match the exact bore and run length your application needs.
🔄 Kink-Resistant Flexibility — The soft-durometer silicone wall bends around corners and through tight spaces without collapsing the bore, maintaining consistent flow even in curved routing paths.
🛡️ Chemical & UV Resistance — Silicone resists ozone, UV exposure, and dilute acids or bases, making it more durable outdoors or in humid environments than standard PVC tubing.
✂️ Cut-to-Length Convenience — Supplied in continuous lengths up to 10M. Cut cleanly with scissors or a utility knife to the exact dimension needed — no waste, no splicing.

❓ Frequently Asked Questions

How do I choose the right ID and OD for my fitting?

Match the tube's inner diameter (ID) to the outer diameter of your barbed fitting. For example, a 4mm barb fits the 4mmID tube. The OD determines how much clearance you need in the routing path. If you're unsure, measure your existing fitting's barb with calipers before selecting a size.

Is this tubing safe for drinking water and home brewing?

Yes. The tubing is made from food grade silicone, which is odorless, tasteless, and non-toxic. It is commonly used in homebrewing siphon lines, aquarium air lines, and water transfer applications where contact with consumable liquids is required.

What is the maximum temperature this silicone tube can handle?

The tubing is rated for continuous use from -60°C to 180°C (-76°F to 356°F). It will not soften or deform at typical sterilization temperatures (e.g., boiling water at 100°C) and remains flexible in sub-zero environments.

Can I use this tubing with petroleum-based fluids or solvents?

No. Silicone rubber is not compatible with petroleum-based oils, fuels, or strong organic solvents. It is designed for water, air, food-grade liquids, and dilute aqueous solutions. For fuel or oil lines, a nitrile or PTFE tube would be more appropriate.

Will the tubing kink if bent around a tight corner?

The soft-durometer silicone wall resists kinking better than rigid PVC or nylon tubing. For very tight bends (bend radius smaller than the tube's OD), a 90° elbow barb fitting is recommended to maintain full bore flow. Smaller ID sizes (2mm–3mm) are more flexible and tolerate tighter bends.

How do I cut the tubing to length, and does it seal cleanly?

Cut with sharp scissors or a utility knife on a flat surface for a clean, square end. A square cut ensures a proper seal against barbed fittings. No special tools are required. The silicone material does not fray or split at the cut edge under normal handling.

Is the purple color food-safe, and will it fade over time?

The pigment used is incorporated into the food-safe silicone compound. Silicone colorants used in food-grade applications are non-leaching. Some minor surface fading may occur with prolonged UV exposure outdoors, but the structural and food-safe properties of the tubing are not affected.
