White Rubber Vacuum Tube — The Flexible Lab Hose That Fits Where Rigid Pipe Can't

Whether you're routing vacuum lines in a chemistry lab, connecting a water pump in a workshop, or building a DIY pneumatic system, finding a hose that seals reliably without cracking or kinking is a constant challenge. Rigid tubing splits at bends, cheap vinyl collapses under vacuum, and mismatched diameters leak at every joint. This flexible white rubber vacuum tube is built for exactly these situations — giving hobbyists, lab technicians, and tradespeople a dependable, cut-to-length solution that installs in seconds.

Each piece is made from white natural rubber compound, chosen for its flexibility across a wide temperature range and its ability to maintain a firm grip on barbed fittings without clamps. Available in inner diameters from 2mm (≈5/64") to 32mm (≈1-1/4"), with matching outer diameters that give you wall thicknesses suited to your pressure requirements. Length options include 1 meter (≈39"), 5 meters (≈196"), and a 1.8-meter fixed-length (≈71") pre-cut option — so you only buy what you need.

Typical use cases include laboratory vacuum pump lines and aspirator connections, aquarium and hydroponic water routing, compressed-air distribution in small workshops, and fluid transfer in DIY brewing or filtration setups — all applications where a flexible rubber vacuum hose for lab and industrial use makes the difference between a clean install and a frustrating workaround.

ℹ️ Compatibility Note: This tubing fits standard metric barbed fittings and glass tubing nozzles. Match your fitting's outer diameter to the tube's inner diameter for a secure friction seal. Sizes range from 2mm ID to 32mm ID — see variant options above.

✅ Key Features of These White Rubber Vacuum Tubes

🔄Stays Flexible Without Kinking — The white rubber compound remains pliable at room temperature and in mildly cooled environments, making it ideal for routing around corners in tight lab benches or workshop setups without collapsing the bore.
📏Wide Size Range in One Listing — Inner diameters from 2mm to 32mm with precisely matched outer diameters let you find the exact wall thickness your application needs, from thin-walled 2mm × 4mm tubing to heavy-walled 25mm × 52mm hose.
✂️Cut-to-Length Convenience — The 1-meter and 5-meter rolls can be trimmed with a utility knife to any length on-site, eliminating waste and letting you fit the tubing precisely to your vacuum line or fluid transfer run.
🔩Friction-Fit Seal on Barbed Fittings — The rubber's natural elasticity creates a tight grip on metric barbed connectors and glass tubing without requiring adhesive or specialized tools, making installation and removal straightforward for repeated use.
🧪Suited for Lab Vacuum and Fluid Transfer — Designed for low-to-medium vacuum applications such as aspirator lines, water jet pumps, and rotary evaporator connections — the kind of flexible rubber hose for laboratory vacuum systems that researchers and technicians reach for first.
🏭Consistent Wall Thickness Across the Bore — Each tube is extruded to maintain uniform wall thickness, which matters for even compression on fittings and predictable flow characteristics in pneumatic and liquid transfer applications.

❓ Frequently Asked Questions

How do I choose the right inner and outer diameter for my application?

Match the inner diameter (ID) to the fitting or nozzle it will slip over. 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 × 16mm OD tube has a 5mm wall, while a 6mm ID × 9mm OD tube has a 1.5mm wall. When in doubt, measure your fitting with calipers and select the closest ID. Common conversions: 6mm ≈ 1/4", 8mm ≈ 5/16", 10mm ≈ 3/8", 12mm ≈ 1/2".

What vacuum pressure can this tubing typically handle?

White rubber vacuum tubing of this type is generally rated for low-to-medium vacuum applications, typically up to -0.08 MPa (approximately -600 mmHg) under normal lab conditions. Actual performance depends on wall thickness, temperature, and the specific rubber compound. For high-vacuum or precision scientific work, please contact us to confirm suitability.

Is this tubing safe for outdoor or UV-exposed environments?

White rubber tubing is generally not recommended for prolonged outdoor UV exposure, as UV radiation can degrade the rubber compound over time. For outdoor use, consider protecting the tubing with conduit or UV-resistant sleeving. For short-term or sheltered outdoor applications, it typically performs adequately.

What fittings or connectors are compatible with this hose?

This tubing is designed to slip over barbed fittings, glass tubing, or nozzles that match the inner diameter. It is compatible with standard barb fittings in metric sizes. No special thread standard is required — the flexible rubber creates a friction seal. Hose clamps can be added for a more secure connection under pressure.

Can I cut this tubing to a custom length?

Yes. The 1-meter and 5-meter options can be cut to any length using a sharp utility knife or tubing cutter. The "1.8 Meter & Fixed length" variant is pre-cut to a fixed length and is not intended for further cutting. A clean, straight cut ensures the best seal on fittings.

What fluids or gases is this tubing compatible with?

This white rubber vacuum tubing is generally compatible with air, water, and mild aqueous solutions. It is commonly used in laboratory vacuum lines, water transfer, and pneumatic systems. It is not recommended for use with strong solvents, oils, fuels, or concentrated acids without confirming chemical compatibility first.

What is the difference between the 1-meter, 5-meter, and 1.8-meter fixed-length options?

The 1-meter and 5-meter options are sold as continuous lengths that you can cut to suit your needs. The 1.8-meter fixed-length option is a pre-formed or pre-cut piece intended for specific applications where a set length is needed — it is not designed to be cut further. Choose based on how much tubing your project requires.
