Colorful Latex Rubber Tubing — Elastic Natural Rubber Tube & Solid Rod, ID 1.6mm–18mm, Multiple Colors

Measure the outer diameter of the fitting or rod you need to slip the tube over — that becomes your minimum ID. For a snug fit, choose an ID slightly smaller than the fitting OD so the latex stretches to grip. For a loose pass-through, match ID to the fitting OD. Wall thickness equals (OD − ID) ÷ 2. For example, the 4mm × 6mm variant has a 1mm wall, while the 6mm × 12mm has a 3mm wall. If you're unsure, size up one step — latex stretches to accommodate.

Natural latex rubber tubing generally achieves tensile strength in the range of 15–25 MPa and elongation at break of 500–800%, depending on wall thickness and compound grade. Thicker walls typically handle higher burst pressures. For pressure-critical or load-bearing applications, contact us to confirm specifications for your specific size before ordering.

Natural latex has good water resistance and performs well in damp or wet conditions. However, prolonged UV exposure can cause surface degradation over time. For long-term outdoor use, consider shielding the tube from direct sunlight or selecting a UV-stabilized alternative. Short-term outdoor applications — garden irrigation, outdoor slingshots, bungee rigging — are generally fine.

Yes. Because latex stretches significantly, it typically seals over barbed fittings whose OD is up to 20–30% larger than the tube's nominal ID. For example, a 4mm ID tube can generally stretch over a 5mm barb. Always verify the specific fitting OD against the tube ID before ordering for pressure-critical applications. No clamps are needed in many low-pressure scenarios.

Hollow tube variants (listed as ID × OD, e.g., 4mm × 6mm) have a through-bore and are used for fluid transfer, slingshot bands, catheter prototypes, and similar applications. Solid rod variants (listed as 2mm Solid, 3mm Solid, 5mm Solid) have no bore and are used as elastic cords, bungee elements, shock absorbers, or craft materials. If you need to pass fluid or air through the tube, choose a hollow variant.

The base latex compound is the same across colors; pigment is added to the rubber mix. In most cases, color does not meaningfully affect tensile strength or elasticity. All seven colors — Orange, Red, Green, Yellow, Black, Ice Blue, and Bright Green — are available across the same size range, making color-coding by circuit or application straightforward.

The standard lengths available are 1m, 2m, and 5m. For longer continuous runs, you can order multiple units and join them with barbed connectors or overlap-and-clamp methods. If you need a specific custom length, contact us before ordering and we will do our best to accommodate your request.
