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

Whether you're routing coolant through a homebrewing chiller, building a peristaltic pump for a lab setup, or replacing a cracked hose on an aquarium filter, finding tubing that is both chemically safe and dimensionally precise is rarely straightforward. This food grade silicone tubing is designed for makers, hobbyists, and tradespeople who need a reliable, flexible rubber hose that won't leach chemicals, crack under heat, or stiffen in cold environments.

Each piece is made from food-grade silicone rubber and is available in 25 Inner Diameter × Outer Diameter combinations ranging from 1×3mm (≈3/64"×1/8") up to 25×31mm (≈1"×1-7/32"), sold in packs of 1, 2, or 5 pieces. Colors available are Pale-Blue and Yellow for easy line identification in multi-hose setups. Wall thickness varies by size — see the specifications table below for your selected variant.

Typical use cases include homebrewing and winemaking transfer lines, aquarium and pond pump connections, laboratory peristaltic pump tubing, DIY beverage dispensing systems, and general-purpose flexible rubber hose routing in automotive coolant overflow or vacuum lines.

🔗 Compatible with standard barb fittings, hose clamps, and push-fit connectors. Match the barb OD to the tube ID for a leak-free seal. Works with brass, stainless steel, and plastic fittings.

✅ Key Features of These Food Grade Silicone Rubber Hoses

🍺Food-Safe Material — Made from food-grade silicone rubber that is non-toxic, odorless, and tasteless, making it suitable for homebrewing transfer lines, beverage dispensing, and food processing fluid paths.
🌡️Wide Temperature Range — Withstands approximately -60°C to +200°C (-76°F to +392°F), handling everything from cold-water aquarium lines to hot-side brewing and steam applications without hardening or cracking.
📐25 ID×OD Size Options — Available from 1×3mm up to 25×31mm, covering a broad range of barb fitting sizes so you can find an exact match for your pump, valve, or connector without adapters.
🎨Color-Coded for Easy Identification — Offered in Pale-Blue and Yellow, allowing you to color-code supply and return lines or differentiate fluid circuits in multi-hose DIY builds at a glance.
☀️UV & Ozone Resistant — Silicone rubber resists UV radiation and ozone degradation, so this flexible rubber hose maintains its elasticity and integrity in outdoor installations longer than standard PVC or latex tubing.
🔧Flexible & Kink-Resistant — The soft, pliable silicone wall bends around tight corners without collapsing the bore, keeping flow unrestricted in compact equipment layouts such as aquarium filters, lab instruments, and DIY cooling loops.

⚠️ Size Tip: The ID (Inner Diameter) is the critical measurement — it must match the outer diameter of the barb or fitting it connects to. If you are unsure of your fitting size, measure the barb OD with calipers and select the matching ID. Contact us before ordering if you need confirmation.

❓ Frequently Asked Questions

How do I choose the right silicone tubing size?

Match the Inner Diameter (ID) to the outer diameter of the fitting or barb it will slip over. For example, a 1/4" (≈6mm) barb fitting typically pairs with 6mm ID tubing. Always verify the OD as well to ensure the tube fits inside any sleeve or clamp. When in doubt, size up by 1mm for a snug but removable fit. Common conversions: 4mm ID ≈ 5/32", 6mm ID ≈ 1/4", 8mm ID ≈ 5/16", 10mm ID ≈ 3/8", 12mm ID ≈ 1/2".

What pressure can this silicone hose handle?

Silicone tubing of this wall thickness generally handles low-to-medium pressure applications — typically up to 30–60 PSI depending on the ID and wall thickness. For high-pressure hydraulic lines, a reinforced hose is recommended. Contact us to confirm the pressure rating for your specific size variant.

Is this tubing safe for food and beverage use?

Yes. This silicone tubing is made from food-grade silicone rubber, which is generally non-toxic, odorless, and tasteless. It is commonly used in homebrewing, winemaking, beverage dispensing, and food processing lines. It does not impart flavor or odor to liquids passing through it.

What temperature range can this silicone hose withstand?

Food-grade silicone rubber typically withstands temperatures from approximately -60°C to +200°C (-76°F to +392°F), making it suitable for both cold-water lines and steam or hot-liquid applications. Prolonged exposure to temperatures above 200°C may reduce service life.

Can I use this tubing outdoors or in wet environments?

Yes. Silicone rubber is inherently resistant to UV radiation, ozone, and moisture, making it well-suited for outdoor and wet environments. It will not crack or harden from sun exposure the way standard rubber or PVC tubing can over time.

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 ID of the tube. It works with brass, stainless steel, and plastic barb fittings. Always match the barb OD to the tube ID for a leak-free connection.

How many pieces come in each order?

Each listing offers 1 Pcs, 2 Pcs, or 5 Pcs packing options. Select your preferred quantity from the Packing Quantity variant selector above. Bulk packs offer a lower per-piece cost.

What is the length of each piece of tubing?

Please contact us to confirm the cut length for your selected size, as lengths may vary by size option. The product listing images and variant details will indicate the standard length available.
