White Rubber Vacuum Tube – Flexible Laboratory Hose Pipe (ID 2mm–25mm)

Measure the outer diameter (OD) of the fitting or nozzle you need to connect to — that should match the inner diameter (ID) of the tube. For example, a 6mm barb fitting typically requires a tube with a 6mm ID. If you need a snug, airtight fit, choose an ID that is equal to or very slightly smaller than the fitting OD. Lengths are available in 1m (≈39.4"), 1.8m (≈70.9"), 2m (≈78.7"), and 3.6m (≈141.7") — select the length closest to your required run to minimize cutting waste.

White rubber vacuum tubing of this type is generally rated for low-to-medium vacuum applications, typically up to -0.09 MPa (≈-13 psi) vacuum and moderate positive pressure. Exact ratings vary by wall thickness and ID — thicker-walled variants generally handle higher differential pressures. For high-vacuum or high-pressure systems, please contact us to confirm suitability before ordering.

White rubber tubing is generally resistant to moisture and can be used in damp environments such as wet labs or condensate lines. However, prolonged UV exposure may cause surface degradation over time. For outdoor installations, we recommend shielding the tubing from direct sunlight or using a UV-protective sleeve to extend service life.

This tubing is designed to slip over standard barb fittings. Choose a fitting whose barb OD matches the tube ID for a secure, leak-resistant connection. Hose clamps are recommended for pressurized or vibration-prone applications. The tubing is compatible with most standard laboratory and pneumatic barb connectors made from brass, stainless steel, or plastic.

Yes. The tubing can be cleanly cut with a sharp utility knife or dedicated tubing cutter. A straight, clean cut ensures the best seal against barb fittings. We offer lengths from 1m up to 3.6m so you can select the closest standard length to minimize waste. For very short custom cuts, order the 1m length and trim to your required dimension.

White rubber tubing is generally compatible with water, air, and many mild aqueous solutions commonly used in laboratory settings. It is not recommended for use with strong solvents, concentrated acids, or hydrocarbons without first verifying chemical compatibility. Contact us if you need guidance for a specific reagent or process fluid.

Wall thickness varies by size and is calculated as (OD − ID) ÷ 2. For example, the 2mm ID × 4mm OD variant has a 1mm wall, while the 6mm ID × 9mm OD variant has a 1.5mm wall, and the 14mm ID × 34mm OD variant has a 10mm wall. In general, wall thickness ranges from 1mm to approximately 10mm depending on the ID/OD combination selected. See variant options for the specific size you need.
