What fittings or standards is this tubing compatible with?

This tubing is compatible with standard barb fittings, hose clamps, and push-fit connectors sized to match the listed inner diameter. It is not threaded and does not follow NPT or BSP thread standards — it connects via friction fit over barbed fittings.

How do I convert the mm sizes to inches?

Divide the mm value by 25.4 to get inches. Common conversions: 4mm ≈ 5/32", 6mm ≈ 1/4", 8mm ≈ 5/16", 10mm ≈ 3/8", 12mm ≈ 1/2", 16mm ≈ 5/8", 19mm ≈ 3/4", 25mm ≈ 1".

Food Grade Silicone Tubing — Flexible Rubber Hose for Brewing, Lab & Fluid Transfer

If you've ever dealt with cracked PVC hose, off-flavors in your homebrew, or a fitting that just won't seal, you know how much the right tubing matters. This food grade silicone tubing is built for makers, brewers, lab technicians, and DIYers who need a flexible, heat-resistant hose that won't contaminate whatever flows through it.

Each piece is 1 meter (≈39.4") of pure silicone rubber hose, available in inner diameters (ID) from 1mm (≈3/64") up to 25mm (≈1"), with matching outer diameters (OD) from 2mm up to 31mm. Wall thickness varies by size. Colors include Transparent, Black, Red, White, Green, Blue, Yellow, and many more — select your combination above.

Typical use cases include homebrewing beer and wine transfer lines, aquarium and pond pump hoses, laboratory fluid handling, peristaltic pump tubing, dairy and food processing lines, and general-purpose flexible silicone hose for DIY projects where PVC or rubber would degrade or impart odor.

🔗 Compatibility Note: This tubing connects via friction fit over standard barb fittings. Match the tubing Inner Diameter (ID) to the outer diameter of your barb or fitting. Not compatible with threaded (NPT/BSP) connections directly — use a barb adapter if needed.

⚠️ Size Tip: If you are unsure of your fitting size, measure the outer diameter of the barb in mm, then select the matching ID. Silicone stretches slightly, so the tubing will grip the barb firmly. Contact us to confirm before ordering if you have specific pressure or temperature requirements.

✅ Key Features of These Food Grade Silicone Tubes

🌡️Wide Temperature Range — Typically rated from -60°C to +200°C (-76°F to +392°F), making this flexible silicone hose suitable for hot-side brewing transfers, steam sterilization, and cold-side chilling lines.
🍺Food-Safe & Taste-Neutral — Made from food grade silicone rubber that is odor-free and non-reactive, so it won't impart flavors or chemicals into beer, wine, milk, juice, or other consumables.
📐30 Size Combinations — ID range from 1mm to 25mm with corresponding OD options, covering everything from micro lab tubing to large-bore brewing hose in a single product line.
🎨Multiple Color Options — Available in Transparent, Black, Red, White, Green, Blue, Yellow, and more — useful for color-coding fluid lines in multi-circuit systems or aquarium setups.
☀️UV & Ozone Resistant — Silicone rubber resists UV degradation and ozone cracking, so this flexible rubber pipe stays pliable and crack-free in outdoor or long-term installations where PVC would harden.
✂️Cut-to-Length Convenience — Each 1-meter length can be trimmed with scissors or a utility knife to fit your exact run, and multiple pieces can be joined with a barb coupler for longer silicone tubing runs.

❓ Frequently Asked Questions

How do I choose the right silicone tubing size?

Match the inner diameter (ID) to the outer diameter of your fitting or barb. For example, a 1/4" (≈6mm) barb fitting typically pairs with ID 6mm tubing. Always measure your fitting OD first, then select the closest ID. Silicone stretches slightly, so the tubing will grip the barb firmly for a leak-resistant seal.

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, autoclaving, and steam applications in most cases. Contact us to confirm if your application involves sustained pressure at elevated temperatures.

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

Yes. This is food grade silicone rubber — non-toxic, odor-free, and taste-neutral. It is widely used in homebrewing, winemaking, dairy processing, and food manufacturing. It will not leach plasticizers or impart off-flavors the way standard PVC tubing can.

Can I use this silicone hose outdoors or in wet environments?

Yes. Silicone is inherently resistant to UV exposure, moisture, and ozone. It will not crack, harden, or become brittle with age the way rubber or PVC tubing typically does, making it a reliable choice for outdoor pond pumps, garden irrigation, and long-term installations.

What fittings is this tubing compatible with?

This flexible rubber hose connects via friction fit over standard barb fittings and hose nipples. It is not threaded and does not follow NPT or BSP standards directly. To connect to a threaded port, use a barb-to-thread adapter of the appropriate size. Hose clamps can be used for higher-pressure applications.

How do I convert mm sizes to inches?

Divide the mm value by 25.4. Common quick conversions: 4mm ≈ 5/32", 6mm ≈ 1/4", 8mm ≈ 5/16", 10mm ≈ 3/8", 12mm ≈ 1/2", 16mm ≈ 5/8", 19mm ≈ 3/4", 25mm ≈ 1". For example, ID 6mm OD 8mm tubing is approximately 1/4" ID × 5/16" OD.

Can I cut this tubing to a custom length?

Yes. Each listing ships as a 1-meter (≈39.4") length that can be cut to any shorter length with scissors or a sharp utility knife. For longer runs, multiple pieces can be joined with a barb coupler of the matching inner diameter. Cut ends are clean and do not require finishing.
