White Flexible Rubber Vacuum Tube — Reliable Laboratory Hose Pipe for Precise Fluid & Air Routing
Lab technicians, aquarium hobbyists, and DIY builders know the frustration of tubing that kinks under light bends, slips off barb fittings mid-experiment, or turns brittle after a few months of use. Whether you're routing vacuum lines on a rotary evaporator, connecting an aquarium air pump, or building a custom pneumatic circuit, you need a white flexible rubber vacuum tube that stays pliable, seals tight, and holds its shape under repeated flexing.
Each piece is a single length of flexible rubber vacuum tubing available in inner diameters (ID) from 1.5mm (≈1/16") to 12mm (≈15/32"), with outer diameters (OD) ranging from 13mm to 28mm depending on the size selected. Lengths are either 0.9m (≈35.4") or 1.8m (≈70.9") — see the variant selector for availability per size. The tubing is white in color, made from flexible rubber, and sold in quantities of 1, 2, or 3 pieces per order.
Typical use cases include laboratory vacuum lines for filtration and distillation setups, aquarium air and water circulation tubing, low-pressure pneumatic connections in DIY projects, and flexible hose routing in tight spaces where rigid pipe would crack or bind. The white color also makes it easy to spot blockages or discoloration during inspection.
🔗
Compatibility Note: This tubing is designed for standard barb fittings. Match the tube's inner diameter to your fitting's outer barb diameter for a secure slip-fit seal. Available IDs: 1.5mm, 2.4mm, 3.2mm, 4.8mm, 6mm, 6.4mm, 7.9mm, 8mm, 9.5mm, 10mm, 12mm.

✅ Key Features of These White Flexible Rubber Vacuum Tubes
-
🔄Stays Flexible Without Kinking — The rubber construction maintains pliability across tight bend radii, making it ideal for flexible laboratory hose routing around equipment and through confined spaces.
-
📏Wide Size Range in One Listing — Inner diameters from 1.5mm to 12mm cover the most common lab and aquarium vacuum tube sizes, so you can match your exact fitting without adapters.
-
🤍White Color for Easy Inspection — The white finish makes it straightforward to spot internal blockages, discoloration from chemical exposure, or flow interruptions at a glance.
-
✂️Cut-to-Length Convenience — Each piece can be trimmed cleanly with a utility knife, letting you dial in the exact run length for bench-top lab setups or aquarium plumbing without waste.
-
🔩Slip-Fit Barb Compatibility — The rubber wall stretches slightly to grip standard plastic, brass, and stainless steel barb connectors, creating a friction seal that resists pull-off in low-pressure vacuum hose applications.
-
📦Multi-Pack Options Available — Order 1, 2, or 3 pieces per size to stock your lab bench or complete a larger DIY rubber tubing project without placing multiple orders.

❓ Frequently Asked Questions
How do I choose the right inner diameter for my application?
Match the tube's inner diameter (ID) to the outer diameter of the fitting or nozzle it will slip over. For example, a 6mm ID tube generally fits a 6mm barb fitting snugly. When in doubt, size down slightly — rubber tubing typically stretches 10–15% to create a secure seal. Available IDs on this listing range from 1.5mm (≈1/16") to 12mm (≈15/32").
What vacuum pressure can this tubing handle?
Flexible rubber vacuum tubing of this type is generally rated for low-to-moderate vacuum applications, typically up to -0.08 MPa (≈-12 psi / 600 mmHg). For high-vacuum systems below 1 Torr, a more rigid or reinforced tubing is recommended. Contact us to confirm suitability for your specific setup.
Is this tubing safe for outdoor or wet environments?
Rubber tubing of this type is generally resistant to moisture and can be used in damp environments. However, prolonged UV exposure may cause surface degradation over time. For permanent outdoor installations, consider protecting the tubing from direct sunlight or using a UV-resistant sleeve.
What fittings or connectors are compatible with this tube?
This tubing is designed to slip over standard barb fittings. Select a barb whose outer diameter matches or is slightly larger than the tube's inner diameter for a secure friction fit. It is compatible with most plastic, brass, and stainless steel barb connectors used in laboratory, aquarium, and pneumatic applications.
Can I use this tubing for aquarium air lines or water flow?
Yes. Flexible rubber vacuum tubing is commonly used for aquarium air pumps, water circulation, and filtration lines. The smaller ID sizes (1.5mm–3.2mm) are typically suited for air lines, while larger sizes (6mm–12mm) work well for water flow applications. Confirm the ID matches your pump outlet before ordering.
What is the difference between the 0.9m and 1.8m length options?
The 0.9m (≈35.4") length is suitable for most bench-top lab setups and short routing runs. The 1.8m (≈70.9") length is available for select sizes and provides extra reach for larger equipment setups or when routing around obstacles. Check the variant selector for length availability per size.
Can I cut this tubing to a custom length?
Yes. Rubber vacuum tubing can be cleanly cut with a sharp utility knife or scissors. A straight, perpendicular cut ensures the best seal against barb fittings. Score lightly first, then cut in one smooth motion to avoid a ragged edge.
