Food Grade Silicone Tubing — Flexible Rubber Hose Pipe for Lab, Brewing & DIY Fluid Lines

Finding a flexible hose that won't crack in the cold, melt near heat, or contaminate what flows through it is a real challenge for home brewers, aquarium hobbyists, lab technicians, and DIY plumbers. Whether you're routing coolant through a custom PC loop, running wort through a homebrew setup, or replacing a cracked appliance hose, standard PVC tubing often falls short — it stiffens, kinks, or off-gasses at temperature extremes.

This food grade silicone tubing is available in 19 Inner Diameter × Outer Diameter combinations, ranging from 1mm×3mm (≈0.04"×0.12") up to 25mm×31mm (≈0.98"×1.22"), and in cut lengths of 1M (≈3.3 ft), 2M (≈6.6 ft), 3M (≈9.8 ft), 5M (≈16.4 ft), and 10M (≈32.8 ft). The wall thickness varies by size — from 1mm on the smallest sizes up to 3mm on larger diameters. Material is food-grade silicone rubber, rated for continuous service from -60 °C (-76 °F) to 180 °C (356 °F).

Typical applications include home brewing and winemaking transfer lines, aquarium and pond water circulation hoses, laboratory peristaltic pump tubing, automotive coolant overflow hoses, and flexible connectors in DIY heating or cooling systems. The soft, kink-resistant wall makes it easy to route around tight bends without flow restriction.

🔗 Compatibility: Fits standard barb fittings, hose clamps, and push-fit connectors. Match the fitting's barb OD to the tube's ID for a secure, leak-resistant seal. Works with plastic, brass, and stainless steel fittings.

✅ Key Features of These Food Grade Silicone Tubing Hoses

  • 🌡️Wide Temperature Range — Rated -60 °C to 180 °C (-76 °F to 356 °F), this flexible silicone hose handles both freezing cold lines and near-boiling fluid transfer without hardening or deforming.
  • 🍺Food-Grade Silicone Material — Made from food-safe silicone rubber that is odorless, tasteless, and free of plasticizers — a reliable choice for home brewing tubing, winemaking hoses, and drinking water lines.
  • 📐19 Size Options — ID×OD combinations from 1mm×3mm to 25mm×31mm let you match the exact fitting diameter without adapters, reducing leak points in your fluid system.
  • 📏5 Length Options — Choose 1M, 2M, 3M, 5M, or 10M to minimize waste. The tubing cuts cleanly with scissors for precise custom lengths on aquarium water lines or lab setups.
  • 🔄Kink-Resistant Flexibility — The soft silicone wall bends around tight corners without collapsing the bore, maintaining consistent flow in peristaltic pump tubing and tight-routed DIY plumbing runs.
  • 🛡️Chemical & UV Resistance — Silicone resists ozone, UV exposure, and a broad range of dilute acids and bases better than standard rubber hose, extending service life in outdoor or chemically active environments.

❓ Frequently Asked Questions

How do I choose the right silicone tubing size?

Measure the outer diameter (OD) of the fitting or barb the tube will slip over — that measurement should match the tube's Inner Diameter (ID). For example, a 6 mm barb fitting typically needs a 6 mm ID tube. If you're between sizes, size down for a snug, leak-resistant fit. All sizes on this listing are expressed as ID × OD in millimeters; to convert, 25.4 mm ≈ 1 inch (so 6mm ID ≈ 15/64").

What temperature range can this silicone tubing handle?

This silicone tubing is rated for continuous use from -60 °C (-76 °F) to 180 °C (356 °F). It generally handles brief excursions slightly above 180 °C without permanent deformation, making it suitable for most hot-water, steam-adjacent, and autoclave-adjacent applications.

Is this tubing safe for food and beverage contact?

Yes. The tubing is made from food-grade silicone, which is generally recognized as safe for contact with food and beverages. It is odorless, tasteless, and does not leach plasticizers. It is commonly used in home brewing, winemaking, aquarium water lines, and kitchen appliance hoses.

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

Silicone is inherently more UV- and ozone-resistant than standard rubber or PVC tubing. For prolonged outdoor exposure, the blue color may fade over time, but the structural integrity of the tube is generally maintained. For extreme outdoor or direct-sunlight applications, additional UV shielding is recommended.

What fittings or connectors are compatible with this tubing?

This tubing is compatible with standard barb fittings, hose clamps, and push-fit connectors sized to match the tube's ID. It works with plastic, stainless steel, and brass barb fittings. No special adapters are required — simply push the tube over a barb fitting of the matching diameter for a secure connection.

How much pressure can this silicone tubing withstand?

Working pressure varies by wall thickness and diameter. Thinner-walled, larger-diameter tubes typically handle lower pressures, while smaller-diameter tubes with thicker walls handle higher pressures. For low-pressure fluid transfer (aquarium, brewing, lab use), this tubing is generally well-suited. For high-pressure hydraulic applications, please contact us to confirm suitability.

Can I cut this tubing to a custom length?

Yes. Silicone tubing cuts cleanly with scissors or a utility knife. Select the length option (1M, 2M, 3M, 5M, or 10M) that best covers your project, then trim to your exact requirement. The cut ends remain smooth and seal well against barb fittings.
