Food Grade Silicone Tubing — Flexible, Odor-Free Hose 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 line, finding a hose that won't leach chemicals, stiffen in the cold, or crack under heat is a real challenge. Standard rubber and PVC tubing often impart odors, harden at low temperatures, or degrade quickly when exposed to cleaning agents — leaving you with contaminated batches or failed seals at the worst possible moment.

This food grade silicone tubing is available in five inner diameter × outer diameter combinations — 2×4mm (≈5/64" ID), 3×5mm (≈1/8" ID), 4×6mm (≈5/32" ID), 5×7mm (≈3/16" ID), and 6×8mm (≈1/4" ID) — with a consistent 1mm wall thickness throughout. Each variant ships as a continuous length from 1M (≈3.3 ft) up to 50M (≈164 ft), so you can order exactly what your project requires. The sky blue color makes it easy to identify fluid lines at a glance in multi-hose setups.

Typical applications include homebrewing transfer lines and siphon hoses, dairy and beverage dispensing systems, aquarium and hydroponics fluid routing, laboratory peristaltic pump tubing, and CPAP or medical-adjacent air line replacement where flexibility and chemical inertness matter.

Compatibility Note: Fits standard metric barbed fittings. Match your fitting's barb OD to the tube's Inner Diameter (ID). For push-fit or compression fittings, verify the outer diameter matches your connector bore. See variant options for exact ID × OD dimensions.

✅ Key Features of These Food Grade Silicone Tubes

  • 🧪Food Grade Silicone Material — Odorless, tasteless, and non-toxic; safe for direct contact with beer, milk, juice, and other consumable liquids without flavor transfer.
  • 🌡️Wide Temperature Range — Rated –60°C to +180°C (–76°F to +356°F), maintaining flexibility in freezer lines and resisting deformation near steam or hot-side brewing equipment.
  • 📐Five Diameter Options — ID × OD combinations from 2×4mm to 6×8mm with a uniform 1mm wall, covering most standard barb fittings used in homebrewing, aquarium, and lab setups.
  • 📏Cut-to-Length Flexibility — Available in 11 lengths from 1M to 50M; order the closest length and trim with scissors — no special tools needed for a clean, square cut.
  • 🔵Sky Blue Color Coding — The distinctive sky blue tint makes it easy to differentiate fluid lines in multi-hose installations, reducing mis-routing errors in complex setups.
  • 🧼Chemical & Cleaning Agent Resistant — Withstands common sanitizers, caustic cleaners, and diluted acids used in brewing and dairy sanitation cycles without swelling, cracking, or off-gassing.

⚠️ Size Tip: The variant selector shows ID × OD in millimeters (e.g., "4x6" = 4mm inner / 6mm outer). Always verify your fitting's barb outer diameter matches the tube's inner diameter before ordering. When in doubt, size down 1mm for a compression-fit seal.

❓ Frequently Asked Questions

How do I choose the right inner diameter for my application?

Match the tube's inner diameter (ID) to your fitting or barb OD. For example, a 1/4" (≈6.35mm) barb typically fits a 6mm ID tube with a snug compression seal. When in doubt, size down by 1mm for a tighter grip. Quick reference:

  • 2mm ID (≈5/64") — micro fluid lines, small peristaltic pumps
  • 3mm ID (≈1/8") — aquarium air lines, small lab tubing
  • 4mm ID (≈5/32") — homebrewing siphon, hydroponics
  • 5mm ID (≈3/16") — beverage dispensing, dairy transfer
  • 6mm ID (≈1/4") — general fluid transfer, wort chiller lines
What pressure can this silicone tubing handle?

With a 1mm wall thickness, this tubing generally handles low-to-medium pressure — typically up to 30–60 PSI depending on diameter and temperature. Smaller diameters with the same wall thickness are generally rated higher. It is not intended for high-pressure hydraulic or pneumatic systems. Contact us to confirm suitability if your application exceeds these ranges.

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

Silicone is generally more UV-resistant than rubber or PVC, making it suitable for moderate outdoor exposure. For long-term outdoor installations — such as garden irrigation or outdoor brewing rigs — shielding the tubing from prolonged direct sunlight is recommended to extend service life.

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

Yes. The flexible silicone wall stretches slightly to seat over standard barbed fittings. The 1mm wall is compatible with most worm-drive hose clamps. For metric fittings, match the barb OD to the tube ID shown in the variant selector (e.g., "4x6" means 4mm ID / 6mm OD).

Is this tubing safe for beer, milk, and other food or beverage contact?

Yes. This tubing is made from food grade silicone — odorless, tasteless, and non-toxic. It does not impart flavor or odor to liquids passing through it, making it well-suited for homebrewing transfer lines, dairy hoses, juice dispensing, and similar food-contact applications.

What temperature range does this silicone hose support?

This tubing is rated from –60°C (–76°F) to +180°C (+356°F). It stays flexible at freezer temperatures — unlike rubber or PVC which can stiffen and crack — and resists deformation near hot-side brewing equipment or steam-adjacent applications. Do not use for direct steam injection without confirming pressure limits.

How do I cut the tubing to a custom length?

Silicone tubing cuts cleanly with sharp scissors or a utility knife. For a square, clean cut, score around the circumference first, then cut through. No special tools are required. Select the closest length variant above and trim to your exact measurement on-site.

Can this tubing be used with a peristaltic pump?

Yes — silicone tubing is the standard choice for peristaltic pumps due to its flexibility, resilience, and chemical inertness. Match the tube's OD and wall thickness to your pump head specifications. The 2×4mm and 3×5mm sizes are typically used in smaller lab and aquarium peristaltic pumps.
