Translucent Silicone Vacuum Tube — Flexible Hose Pipe for Industrial, Automotive & DIY Use

When standard PVC or rubber tubing cracks under heat, stiffens in the cold, or discolors from UV exposure, the job stalls — and so does your project. Whether you are routing coolant lines in an engine bay, building a laboratory vacuum system, or plumbing a food-processing rig, you need a hose that stays flexible and leak-free across a wide temperature range. This translucent silicone vacuum tube is built for exactly those demanding environments.

Each order is a continuous cut of pure silicone tubing, available in lengths of 1 metre (≈3.3 ft), 5 metres (≈16.4 ft), or 10 metres (≈32.8 ft). Inner diameters range from 2mm (≈5/64") to 30mm (≈1-3/16"), with matching outer diameters selected to provide a practical wall thickness for each bore size. The material is translucent, so you can visually confirm flow without cutting into the line. Temperature rating spans -70°C to 260°C (-94°F to 500°F).

Typical use cases include automotive vacuum line replacement, peristaltic pump tubing, aquarium and hydroponics fluid transfer, laboratory gas and liquid routing, and food-grade beverage or dairy line applications where a flexible silicone hose is required.

🔵 Compatibility: Fits standard barbed fittings, hose nipples, and push-fit connectors matching the listed Inner Diameter. Verify your fitting OD matches the tube ID before ordering.

⚠️ Size tip: The ID (Inner Diameter) must match your fitting's outer diameter for a secure, leak-free seal. Use calipers to measure your fitting before selecting a variant.

✅ Key Features of These Translucent Silicone Vacuum Tubes

🌡️ Wide Temperature Range — Rated -70°C to 260°C (-94°F to 500°F), this silicone vacuum hose stays pliable in freezing conditions and holds its shape under sustained high heat, making it suitable for engine bays, autoclaves, and steam lines.
👁️ Translucent Wall for Visual Flow Monitoring — The clear silicone construction lets you confirm liquid or gas flow at a glance without disconnecting the line — a practical advantage in laboratory, brewing, and medical equipment setups.
🔄 Flexible and Kink-Resistant — Soft silicone rubber bends around tight corners without collapsing the bore, reducing the need for elbow fittings in confined routing paths such as automotive vacuum lines or compact machinery.
🧪 Chemical and UV Resistance — Silicone resists ozone, UV radiation, dilute acids, bases, and many oils. Unlike standard rubber hose, it does not harden, crack, or degrade with prolonged outdoor or chemical exposure.
📏 Wide Size Selection — ID 2mm to 30mm — With over 70 ID × OD combinations and three cut lengths, you can match this flexible silicone hose pipe precisely to your fitting size rather than forcing an approximate fit.
🍺 Food-Contact Silicone Material — Made from platinum-cure silicone, this tubing is generally suitable for food, beverage, and dairy transfer lines where a non-toxic, odorless, and tasteless flexible hose is required.

❓ Frequently Asked Questions

How do I choose the right ID and OD for my application?

Match the Inner Diameter (ID) to the outer diameter of the fitting or nipple you are connecting to. The Outer Diameter (OD) determines wall thickness — a larger OD relative to the ID means a thicker wall and generally higher pressure tolerance. For example, a 6mm ID × 10mm OD tube has a 2mm wall on each side (≈0.08 in per side). If you are unsure, measure your fitting with calipers before ordering. Wall thickness = (OD − ID) ÷ 2.

What pressure can this silicone vacuum tube handle?

Pressure rating depends on wall thickness and bore diameter. Thinner-walled, larger-bore tubes typically handle lower pressures. For light vacuum and low-pressure air or fluid transfer, silicone tubing of this type generally performs well. For high-pressure hydraulic or pneumatic use, please contact us to confirm suitability for your specific ID × OD combination.

Can this tube be used outdoors or in high-humidity environments?

Yes. Silicone is inherently resistant to UV radiation, ozone, and moisture, making it suitable for outdoor and high-humidity installations. It does not crack or harden with prolonged sun exposure the way standard rubber or PVC tubing typically does.

Is this silicone tubing food-safe or medical-grade?

This tubing is made from platinum-cure silicone and is generally considered suitable for food-contact applications such as beverage, brewing, and dairy lines. If you require certified FDA or NSF compliance for a regulated food or medical process, please contact us to confirm the certification status before ordering.

What fluids and chemicals is this tube compatible with?

Silicone tubing is compatible with water, air, steam (within temperature limits), many oils, and dilute acids and bases. It is not recommended for concentrated solvents such as acetone, toluene, or chlorinated hydrocarbons. When in doubt, perform a short immersion test before committing to a full installation.

How do I choose between 1m, 5m, and 10m lengths?

Order 1m for prototyping, repairs, or short single runs. Choose 5m or 10m if you are routing tubing through a machine, vehicle, or plumbing system where you need continuous runs without joins. Buying longer lengths reduces the number of fittings and potential leak points in your system.

What is the temperature range and can it handle steam?

This tube is rated from -70°C (-94°F) to 260°C (500°F), which covers atmospheric-pressure steam (100°C / 212°F) comfortably. For pressurized steam above atmospheric pressure, verify that the wall thickness of your chosen variant is adequate for your operating pressure before use.
