Food Grade Silicone Tube — Flexible Green Hose Pipe for Brewing, Dairy & Lab Use

Whether you're routing wort through a homebrewing setup, transferring milk in a small dairy operation, or plumbing a lab fluid system, finding tubing that won't contaminate your product — or crack under temperature swings — is a real challenge. Standard PVC hose gets stiff in the cold, absorbs odors over time, and isn't rated for food contact. This bright green food grade silicone tube is built for exactly those situations: flexible at sub-zero temperatures, stable at high heat, and completely inert to the liquids it carries.

Each order is a continuous length of silicone tubing, available in five inner diameter × outer diameter combinations — 2×4mm (≈5/64" × 5/32"), 3×5mm (≈1/8" × 13/64"), 4×6mm (≈5/32" × 15/64"), 5×7mm (≈13/64" × 9/32"), and 6×8mm (≈15/64" × 5/16") — and eleven cut lengths from 1M (≈3.3ft) to 50M (≈164ft). Wall thickness is 1mm across all sizes. Material is food grade silicone with a Shore A hardness of approximately 60°, rated for continuous use from -60°C to +180°C (-76°F to +356°F).

Typical applications include homebrewing beer and cider transfer lines, peristaltic pump tubing for dairy or beverage dispensing, aquarium and hydroponics fluid routing, and laboratory fluid handling where chemical inertness and autoclavability are required. The bright green color makes it easy to identify dedicated food-contact lines in multi-hose setups.

ℹ️ Compatibility Note: Inner diameters are metric (2–6mm). Verify your fitting's barb OD matches the tube ID before ordering. Standard metric barb fittings and worm-drive hose clamps are compatible. For US standard fittings, see the FAQ below for inch equivalents.

✅ Key Features of These Food Grade Silicone Tubes

🍺Certified Food Grade Silicone — Non-toxic, odorless, and taste-neutral; safe for direct contact with beer, milk, juice, and other consumable liquids without leaching plasticizers or additives.
🌡️Wide Temperature Range — Rated from -60°C to +180°C (-76°F to +356°F), so this flexible silicone hose pipe stays pliable in cold storage and holds up during hot-side brewing or steam sterilization cycles.
🔄Kink-Resistant Flexibility — Shore A 60° hardness strikes the balance between soft enough to compress for peristaltic pumps and firm enough to resist kinking around tight bends in confined equipment spaces.
📏Five Diameter Options, Eleven Lengths — ID × OD combinations from 2×4mm to 6×8mm, with lengths from 1M to 50M, let you order exactly what your project needs — no splicing short pieces together or paying for excess footage.
🧪Chemically Inert & Autoclavable — Silicone does not react with dilute acids, alkalis, or common sanitizers (Star San, iodophor), making this tubing suitable for lab fluid handling and repeated sterilization cycles up to 180°C.
🟢High-Visibility Bright Green Color — The distinctive green color helps you instantly identify food-contact or dedicated-use lines in multi-hose installations, reducing cross-contamination risk in complex setups.

⚠️ Size Tip: The ID listed is the inner bore — match it to the outer diameter of your barb fitting for a secure, leak-free connection. When in doubt, size down: silicone stretches slightly for a snug fit.

❓ Frequently Asked Questions

How do I choose the right size silicone tube?

Match the inner diameter (ID) to the outer diameter of the fitting or barb it will connect to. For example, a 1/4" (6.35mm) barb typically pairs with a 6mm ID tube. When in doubt, size down slightly — silicone stretches and a snug fit seals better than a loose one. Inch equivalents: 2mm ≈ 5/64", 3mm ≈ 1/8", 4mm ≈ 5/32", 5mm ≈ 13/64", 6mm ≈ 15/64".

What pressure can this silicone tubing handle?

Food grade silicone tubing of this wall thickness (1mm) generally handles low-to-moderate pressures, typically up to 30–60 PSI depending on diameter and temperature. For high-pressure applications, please contact us to confirm suitability before ordering.

Can this tubing be used outdoors or in UV-exposed environments?

Silicone is generally more UV-resistant than PVC or rubber, but prolonged direct sunlight exposure can cause gradual surface degradation over time. For outdoor installations, shielding the tubing from direct UV is recommended for maximum service life.

Is this tubing compatible with standard barb fittings and hose clamps?

Yes. The metric inner diameters (2, 3, 4, 5, 6mm) are compatible with standard metric barb fittings. For US standard fittings, check the inch equivalents listed above. Standard worm-drive hose clamps work well with this tubing — select a clamp sized for the outer diameter of the tube.

Is this tubing safe for beer brewing and food contact?

Yes. This tubing is made from food grade silicone, which is non-toxic, odorless, and does not impart taste or color to liquids. It is commonly used in homebrewing, dairy transfer, and food processing applications. The material does not contain BPA, phthalates, or other plasticizers.

What length should I order for my project?

Measure the total run of tubing needed, then add 10–15% for bends, connections, and trimming. Available lengths range from 1M (≈3.3ft) to 50M (≈164ft). For most homebrewing setups, 1M–2M is sufficient per connection; lab or industrial runs may require 5M–15M or more. Ordering a longer continuous length is generally better than splicing multiple short pieces.

How do I clean and sterilize this silicone tubing?

Silicone tubing can generally be cleaned with hot water, mild detergent, or food-safe sanitizers such as Star San or iodophor. It is typically autoclavable and can withstand steam sterilization at temperatures up to 180°C (356°F). Avoid harsh solvents or bleach-based cleaners for repeated use, as these may degrade the surface over time.
