Food Grade Silicone Vacuum Hose — Flexible Blue Rubber Tubing for Aquariums, Automotive & Air Lines

Finding a hose that holds up to heat, stays flexible in the cold, and won't contaminate what flows through it is harder than it sounds. Whether you're routing vacuum lines under a hood, running air to an aquarium airstone, or plumbing a homebrew or food-processing setup, generic PVC tubing cracks, stiffens, and off-gasses in ways that silicone simply doesn't. This food grade silicone vacuum hose is built for builders, hobbyists, and tradespeople who need a reliable, long-lasting tube they can cut to length and forget about.

Each order is sold by the meter in a single continuous length — choose from 1M (≈39"), 2M (≈78.7"), 3M (≈9.8 ft), 5M (≈16.4 ft), 10M (≈32.8 ft), or 20M (≈65.6 ft). The hose is available in 13 inner diameter × outer diameter combinations ranging from 3mm × 6mm (≈1/8" ID) up to 14mm × 18mm (≈9/16" ID), covering the most common metric barb fitting sizes used in automotive, aquarium, laboratory, and food-grade plumbing. The blue color makes routing easy to trace at a glance.

Typical applications include automotive vacuum line replacement and boost hose routing, aquarium and fish tank air supply lines, homebrewing and beverage transfer tubing, laboratory fluid handling, and HVAC or pneumatic low-pressure air circuits. The flexibility of silicone rubber makes it especially useful anywhere a rigid tube would kink or fatigue over time.

ℹ️ Compatibility Note: Select the inner diameter (ID) that matches your barb fitting or outlet size. This hose is designed for low-to-medium pressure applications — typically vacuum, air, and fluid transfer lines. Confirm operating pressure and temperature requirements before use in high-pressure systems.

✅ Key Features of These Food Grade Silicone Vacuum Hoses

  • 🧪Food Grade Silicone Material — Made from non-toxic, odorless silicone rubber that is safe for contact with food, beverages, and potable water in typical transfer applications.
  • 🌡️Wide Temperature Tolerance — Silicone rubber generally maintains flexibility from approximately -60 °C to +200 °C, outperforming PVC and standard rubber in both cold and heat.
  • 📏13 Size Options, 6 Cut Lengths — ID × OD combinations from 3×6mm to 14×18mm, sold in 1M through 20M runs, so you get exactly the silicone vacuum tubing size your project requires.
  • 🔵High-Visibility Blue Color — The consistent blue finish makes routing and tracing lines straightforward in engine bays, aquarium cabinets, and equipment enclosures.
  • 🔧Barb-Fitting Ready — Fits standard metric barb connectors and hose clamps; the flexible wall conforms snugly to barbs for a secure, leak-resistant connection without adhesives.
  • ✂️Cut-to-Length Convenience — Supplied as a continuous length that cuts cleanly with a utility knife, eliminating waste and letting you tailor the run to your exact aquarium air line or automotive vacuum hose routing.

❓ Frequently Asked Questions

How do I choose the right size silicone vacuum hose?

Match the inner diameter (ID) to your fitting or barb size. For example, a 6mm ID hose fits a 6mm barb fitting. If you are unsure, measure the outside of the fitting and select the ID that is equal to or slightly smaller for a snug, leak-free seal. Lengths range from 1M (≈39") to 20M (≈65.6 ft), so order the run you need plus a small buffer for trimming.

What temperature range can this silicone hose handle?

Silicone rubber generally withstands continuous temperatures from approximately -60 °C (-76 °F) to +200 °C (+392 °F), making it suitable for most automotive vacuum, cooling-adjacent, and food-processing applications. For extreme heat cycles, confirm your specific operating conditions before use.

Is this hose safe for food and beverage contact?

Yes. 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. If your application requires a specific FDA or NSF certification, please contact us to confirm compliance for your use case.

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

Silicone rubber typically offers better UV and ozone resistance than standard rubber or PVC tubing, making it a reasonable choice for outdoor or semi-exposed installations. For prolonged direct sunlight exposure, consider adding a protective sleeve or conduit for extended service life.

What fittings or connectors are compatible with this hose?

This hose is compatible with standard barb fittings, push-fit connectors, and hose clamps sized to match the inner diameter you select. It works with metric barb fittings (e.g., 3mm, 4mm, 6mm, 8mm, 10mm, 12mm, 14mm) commonly used in aquarium, automotive, and laboratory setups. A hose clamp is recommended for any pressurized connection.

How do I cut the hose to a custom length?

A sharp utility knife or scissors will produce a clean, square cut. Mark your cut line with a marker and cut in a single smooth motion. Silicone is flexible and forgiving, so minor imperfections in the cut generally do not affect sealing performance when used with a barb fitting and clamp.

Which size should I choose for an aquarium air line?

For standard aquarium air pumps and airstones, the 3mm ID × 6mm OD or 4mm ID × 7mm OD sizes are typically the most common fits. Check your air pump outlet diameter before ordering. If your pump uses a larger outlet, step up to the 6mm or 8mm ID options.
