Silicone Rubber Tubing ID 3–10mm — Flexible, Food-Grade Hose for Brewing, Labs & DIY

Finding a hose that won't kink, crack, or leach chemicals into your beer, aquarium, or lab setup is harder than it should be. Whether you're routing coolant through a homebrewing chiller, building a peristaltic pump, or replacing a cracked rubber line on a piece of equipment, you need tubing that stays flexible at both extremes of temperature and holds a clean seal on a barbed fitting.

This listing offers food-grade silicone soft rubber tubing sold by the meter in nine ID×OD size combinations — from 3×5mm (≈1/8" ID) up to 10×12mm (≈3/8" ID) — and in five cut lengths: 1m (≈3.3 ft), 3m (≈9.8 ft), 5m (≈16.4 ft), 10m (≈32.8 ft), and 20m (≈65.6 ft). Fourteen color options are available across most sizes, including transparent, black, red, white, and a range of vivid colors for color-coded line identification.

Typical use cases include homebrewing transfer lines and wort chillers, aquarium and fish tank air and water lines, peristaltic pump tubing for laboratory dispensing, vacuum and low-pressure pneumatic lines in DIY electronics and robotics, and flexible silicone hose for automotive coolant overflow reservoirs.

⚠️ Wall thickness varies by size. Verify the ID and OD against your fitting before ordering. See the size chart in the specifications table below.

✅ Compatible with standard metric barbed fittings, hose tails, and nipples. Suitable for food, beverage, aquarium, laboratory, and low-pressure pneumatic applications. Not designed for high-pressure hydraulic use.

✅ Key Features of These Silicone Rubber Tubes

🌡️Wide Temperature Range — Silicone tubing typically remains flexible from approximately -60°C (-76°F) to +200°C (+392°F), making it suitable for both hot-side brewing transfers and cold-side chilling lines.
🍺Food-Grade Material — Made from food-safe silicone that is odorless, tasteless, and non-toxic, so it won't impart off-flavors to beer, wine, juice, or dairy lines.
🎨14 Color Options — Available in transparent, black, red, white, yellow, green, blue, sky blue, dark blue, orange, orange red, transparent red, pink, and purple — ideal for color-coded tubing runs in multi-line setups.
📐9 Size Combinations — ID×OD options from 3×5mm up to 10×12mm cover the most common barb fitting sizes used in aquariums, brewing, and laboratory equipment.
🔄Flexible and Kink-Resistant — Silicone's inherent elasticity allows tight bends without collapsing the bore, maintaining consistent flow in confined routing paths.
✂️Cut-to-Length Options — Choose from 1m, 3m, 5m, 10m, or 20m lengths to minimize waste and reduce the number of joins in longer runs.

❓ Frequently Asked Questions

How do I choose the right silicone tube size?

Match the ID (inner diameter) to the outer diameter of the fitting or barb it will slip over. For example, a 5mm barb typically requires a 5×8mm tube (ID 5mm, OD 8mm). If you need an inch reference: 3mm ≈ 1/8" and 10mm ≈ 3/8". When in doubt, size up by 0.5–1mm for a snug push-fit.

What temperature range can this silicone tubing handle?

Silicone tubing generally handles continuous service from approximately -60°C (-76°F) to +200°C (+392°F). Short-term peaks up to 230°C are typically tolerated. Always verify your specific application requirements before use.

Is this tubing safe for food and beverage contact?

This tubing is made from food-grade silicone, which is generally recognized as safe for contact with food and beverages. It is odorless, tasteless, and non-toxic, making it suitable for beer brewing, winemaking, and dairy transfer lines. Confirm compliance with your local food-safety regulations before use in commercial applications.

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

Silicone has good UV and ozone resistance compared to rubber alternatives, making it generally suitable for outdoor use. However, prolonged direct UV exposure over many years may cause minor surface degradation. For critical outdoor installations, inspect the tubing periodically.

What fittings or standards is this tubing compatible with?

This is a plain-bore silicone tube designed to slip over barbed fittings, hose tails, or nipples. It does not have threaded ends. Compatibility depends on the OD of the fitting barb matching the tube ID. It works with standard metric barb fittings commonly used in aquariums, brewing, and laboratory equipment.

How do I select the right length for my project?

Measure the run between your two connection points and add at least 10–15% extra for routing around obstacles and for secure barb engagement at each end. Available lengths are 1m, 3m, 5m, 10m, and 20m. For longer continuous runs, the 10m or 20m options reduce the number of joins.

Can this tubing handle pressure, and what is its burst pressure?

Silicone tubing of these wall thicknesses typically handles low-to-moderate pressures suitable for gravity-fed or peristaltic pump applications. Burst pressure varies by wall thickness and ID; thinner-walled sizes (e.g., 3×5mm) generally have lower pressure ratings than thicker-walled sizes (e.g., 8×12mm). Contact us to confirm if your application exceeds 0.3 MPa (≈43 psi).
