Standard PVC tubing stiffens in the cold, degrades with heat, and can impart an unpleasant taste or odor — none of which you want anywhere near food or sensitive equipment. This food grade silicone tubing is built for exactly those situations, giving DIYers, hobbyists, and small-scale operators a reliable, flexible solution they can trust.\u003c\/p\u003e\n    \u003cp\u003eEach order is a continuous length of silicone rubber hose in your chosen size combination. Inner Diameter (ID) options run from 2mm (≈5\/64\") to 6mm (≈15\/64\"), with corresponding Outer Diameters (OD) from 4mm (≈5\/32\") to 8mm (≈5\/16\") — all with a consistent 1mm wall thickness. Lengths are available in 1M (≈3.3 ft), 2M (≈6.6 ft), 3M (≈9.8 ft), 5M (≈16.4 ft), and 10M (≈32.8 ft). The tubing is rated for continuous service from -60°C to 180°C (-76°F to 356°F) and is made from food-grade silicone that is odor-free and taste-neutral.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include homebrewing and winemaking transfer lines, aquarium air and water routing, peristaltic pump tubing, laboratory fluid handling, and small-appliance coolant hoses.
