White Food Grade Silicone Rubber Tube — Flexible Hose for Water, Aquarium & Automotive Use

Finding a hose that won't crack in the cold, leach odors into your water, or stiffen up after a season of use is harder than it should be. Whether you're routing coolant in a classic car, building a recirculating aquarium system, or plumbing a homebrewing setup, this white food grade silicone rubber tube gives hobbyists, makers, and small-shop technicians a reliable, flexible solution that holds its shape run after run.

Each listing covers a single continuous length of silicone tubing — available in 1M (≈3.3 ft), 2M (≈6.6 ft), 5M (≈16.4 ft), and 10M (≈32.8 ft) cuts — in 17 inner-diameter sizes ranging from 1mm (≈1/32") up to 20mm (≈3/4"). Wall thickness varies by size; for example, the 3mm ID × 5mm OD variant has a 1mm wall, while the 8mm ID × 12mm OD variant has a 2mm wall. The tubing is white in color and made from food-grade silicone rubber.

Typical use cases include aquarium air and water lines where an odor-free flexible silicone aquarium hose is essential, automotive heater-core bypass and coolant overflow routing where a heat-resistant silicone rubber hose is needed, and laboratory or homebrewing transfer lines where a food-safe flexible tubing solution is required.

ℹ️ Compatibility note: Size is listed as Inner Diameter × Outer Diameter. Match the inner diameter to your barb fitting or nozzle OD for a secure slip fit. Lengths are sold per continuous piece — 1M, 2M, 5M, or 10M. Select your combination above before adding to cart.

✅ Key Features of These Food Grade Silicone Rubber Tubes

🍽️Food-Safe Material — Made from food-grade silicone that is odorless, tasteless, and free of BPA and harmful plasticizers, making it suitable for drinking water lines, homebrewing transfer hoses, and food processing equipment.
🌡️Wide Temperature Tolerance — Remains flexible and functional across a broad range, typically from -60°C (-76°F) to +200°C (+392°F), so it handles both cold aquarium water lines and moderate-heat automotive coolant bypass routing without hardening or cracking.
📐17 Diameter Options — Inner diameters from 1mm (≈1/32") to 20mm (≈3/4") let you match the exact barb or nozzle size in your system, eliminating the need for reducers or adapters in most standard metric setups.
📏Cut-to-Length Flexibility — Available in 1M, 2M, 5M, and 10M continuous lengths so you can order exactly what your project needs — whether it's a short aquarium air line or a longer automotive heater hose run.
🔧Barb-Fitting Ready — The soft, elastic silicone wall stretches slightly to grip standard metric barb fittings securely. A worm-drive hose clamp adds extra retention for pressurized lines without cutting into the tube wall.
☀️UV & Ozone Resistant — Silicone rubber resists UV degradation and ozone attack better than standard PVC or latex tubing, making this flexible silicone hose a durable choice for outdoor plumbing runs and engine-bay routing.

❓ Frequently Asked Questions

How do I choose the right tube size?

Match the inner diameter (ID) to the outer diameter of the fitting or barb it will slip over. For example, a 6mm barb fitting typically pairs with a 6mm ID tube. If you need a snug seal, choose an ID that is 0.5–1mm smaller than the barb. All sizes are listed as Inner Dia. × Outer Dia. in millimeters — for reference, 10mm ≈ 3/8" and 20mm ≈ 3/4".

Is this tubing safe for drinking water and food contact?

Yes. This tubing is made from food-grade silicone that is generally free of BPA, phthalates, and harmful plasticizers. It is odorless and tasteless, making it suitable for drinking water lines, homebrewing, and food processing applications. If your application requires a specific FDA or NSF certification, please contact us to confirm before ordering.

What temperature range can this silicone hose handle?

Silicone rubber tubing typically withstands temperatures from approximately -60°C (-76°F) to +200°C (+392°F), making it suitable for both cold-water aquarium lines and moderate-heat automotive coolant bypass applications. Continuous exposure near the upper limit may gradually reduce flexibility over time.

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

Silicone has good UV and ozone resistance compared to standard rubber or PVC tubing, making it generally suitable for outdoor use. For prolonged direct sunlight exposure, consider adding a protective sleeve or routing the hose in a shaded area to maximize service life.

Will this tubing work with standard barb fittings and hose clamps?

Yes. The flexible silicone wall stretches slightly to grip barb fittings securely. For pressure applications, a standard worm-drive hose clamp is recommended. The tubing is compatible with metric barb fittings that match the listed inner diameter. For NPT or BSP threaded connections, use an appropriate barb-to-thread adapter.

How much pressure can this silicone tube handle?

Working pressure varies by wall thickness and diameter. Smaller diameters with thicker walls generally handle higher pressures. For low-pressure gravity-fed or aquarium applications, the tubing performs reliably without clamping. For pressurized systems, use hose clamps and contact us to confirm suitability for your specific pressure rating.

How do I cut the tubing to a custom length?

A sharp utility knife or scissors will produce a clean, square cut. For the cleanest edge on larger diameters (10mm ID and above), a tubing cutter or a miter box guide is recommended. Avoid sawing motions that can leave ragged edges and compromise the seal at fittings.
