Whether you're a DIY mechanic routing coolant lines, a hobbyist building a pneumatic system, or a plumber needing a flexible connector, a mismatched or brittle hose can cause leaks, downtime, and frustration. This red silicone vacuum hose is built for builders and fixers who need a reliable, heat-resistant tube that fits right the first time.\u003c\/p\u003e\n\n    \u003cp\u003eEach order includes a continuous length of silicone rubber hose in your chosen size combination. Available in inner diameters (ID) from 2mm (≈5\/64\") to 38mm (≈1-1\/2\"), with matching outer diameters (OD) ranging from 4mm to 44mm, and lengths of 1 metre (≈3.3 ft), 5 metres (≈16.4 ft), or 10 metres (≈32.8 ft). The wall thickness varies by size — for example, the 6mm ID × 8mm OD variant has a 1mm wall, while larger sizes carry proportionally thicker walls. Material is 100% silicone rubber, which remains flexible across a wide temperature range.\u003c\/p\u003e\n\n    \u003cp\u003eTypical applications include automotive vacuum lines and boost hose routing, coolant bypass tubes and radiator overflow connections, air compressor and pneumatic tool hose runs, and general-purpose water or oil transfer in workshop and garden settings.
