How do I decide between the 3*5mm, 5*8mm, 7*10mm, and 1.5*3mm sizes?

The size format is ID*OD (inner diameter × outer diameter). Choose based on your fitting size and flow rate needs: 1.5*3mm is ideal for micro-dosing or small lab lines; 3*5mm suits standard aquarium and vacuum lines; 5*8mm is popular for homebrewing and water transfer; 7*10mm handles higher flow rates for larger equipment.

Clear Food Grade Silicone Tubing — Flexible, Safe & Temperature-Resistant Hose for Brewing, Lab & Home Use

Homebrewers, aquarium hobbyists, and lab technicians all share the same frustration: standard PVC tubing that stiffens in the cold, cracks under heat, or leaves a plastic taste in whatever flows through it. This clear food grade silicone tubing is built to solve exactly that — delivering a flexible, chemically inert, and odorless fluid transfer solution that holds up across a wide range of applications.

Each order is sold by the meter in a continuous roll. Available in four inner/outer diameter combinations — 1.5*3mm, 3*5mm, 5*8mm, and 7*10mm — and lengths from 1M (≈3.3 ft) up to 50M (≈164 ft). Wall thickness is approximately 1mm across all sizes. The tubing is clear, allowing visual flow monitoring, and maintains flexibility across a working temperature range of -60°C to 200°C (-76°F to 392°F) with a Shore hardness of 65°.

Typical use cases include homebrewing beer and wine transfer lines, aquarium and pond pump connections, vacuum pump lines for automotive and HVAC work, laboratory fluid handling, and medical-adjacent equipment where non-toxic tubing is required. The clear silicone construction makes it easy to spot blockages or contamination without disconnecting the line.

ℹ️ Compatibility Note: Size format is ID × OD (inner diameter × outer diameter). Match the tube ID to your barb fitting OD for a secure slip fit. Hose clamps recommended for pressurized lines.

✅ Key Features of These Clear Food Grade Silicone Tubes

🧪Food Grade & Non-Toxic — Made from food-safe silicone that is odorless, tasteless, and free from BPA and plasticizers, making it suitable for direct contact with beverages, dairy, and food processing lines.
🌡️Wide Temperature Range — Rated from -60°C to 200°C (-76°F to 392°F), this silicone vacuum hose stays flexible in freezing conditions and resists softening or off-gassing at elevated temperatures.
🔍Crystal-Clear Transparency — The clear silicone wall lets you monitor fluid flow, detect air bubbles, and spot contamination at a glance — no need to disconnect the line for inspection.
📏Multiple Sizes & Cut-to-Length Rolls — Four ID/OD combinations (1.5*3mm through 7*10mm) and lengths from 1M to 50M give you the flexibility to order exactly what your project needs, whether it's a short aquarium connection or a full brewing setup.
💪Kink-Resistant Flexibility — The 65° Shore hardness strikes a balance between softness for easy routing around bends and enough body to resist collapsing under vacuum, which is critical for homebrewing siphon lines and vacuum pump applications.
🛡️UV & Ozone Resistant — Unlike PVC tubing that becomes brittle and discolored outdoors, silicone rubber resists UV degradation and ozone exposure, making this hose a reliable choice for outdoor equipment and long-term installations.

⚠️ Size Tip: If you are between sizes, size up for a snug fit over barb fittings. For vacuum applications, a tighter fit reduces the risk of air leaks.

❓ Frequently Asked Questions

How do I choose the right tube size and length?

Match the inner diameter (ID) to your fitting or barb size. For example, a 5mm barb fitting typically pairs with the 5*8mm tube (5mm ID). Length depends on your run — measure the distance between connection points and add 10–15% for routing. Available lengths range from 1M (≈3.3 ft) to 50M (≈164 ft).

What pressure can this silicone tubing handle?

Silicone tubing of this type generally handles low-to-medium vacuum and pressure applications. For homebrewing, aquarium, and laboratory use, typical working pressure is sufficient. For high-pressure hydraulic applications, this tubing is not recommended — contact us to confirm suitability for your specific setup.

Can this tubing be used outdoors or in high-temperature environments?

Yes. This silicone tubing is rated for -60°C to 200°C (-76°F to 392°F), making it suitable for outdoor use, steam exposure, and high-heat applications. Silicone is also UV-resistant and does not crack or harden over time the way PVC does.

Is this tubing safe for food and beverage contact?

Yes. This is food grade silicone, meaning it is non-toxic, odorless, and does not leach chemicals into liquids. It is commonly used in homebrewing, winemaking, dairy transfer lines, and food processing equipment where material safety is a requirement.

What fittings or connectors are compatible with this tubing?

This tubing is designed to slip over standard barb fittings. Match the barb OD to the tube ID for a secure fit. For example, the 3*5mm tube (3mm ID) fits a 3mm barb. Hose clamps can be added for extra security in pressurized or high-vibration lines.

How do I decide between the 1.5*3mm, 3*5mm, 5*8mm, and 7*10mm sizes?

The size format is ID*OD (inner diameter × outer diameter). Choose based on your fitting size and flow rate needs:

1.5*3mm — Micro-dosing, small lab lines, precision fluid control
3*5mm — Standard aquarium tubing, vacuum lines, small pump connections
5*8mm — Homebrewing beer and wine transfer, water pumps, general fluid lines
7*10mm — Higher flow rate applications, larger equipment, industrial-adjacent use

Can I cut this tubing to a custom length?

Yes. Silicone tubing cuts cleanly with scissors or a utility knife — no special tools required. Ordering a longer roll (10M, 20M, or 50M) gives you the flexibility to cut multiple runs from a single purchase, which is generally more cost-effective than buying several short lengths.
