Mismatched inner diameters cause leaks; opaque hose makes it impossible to spot blockages or air bubbles; stiff tubing kinks the moment you route it around a corner. This clear PVC flexible tubing is stocked in 17 size combinations specifically so hobbyists, DIYers, and small-scale operators can get an exact fit without ordering a full industrial spool.\u003c\/p\u003e\n    \u003cp\u003eEach roll contains one continuous length of clear, flexible PVC hose. Available inner diameters range from 2mm (≈5\/64\") to 13mm (≈1\/2\"), with matching outer diameters from 3mm to 18mm, giving wall thicknesses of approximately 0.5mm to 2.5mm depending on the size selected. Rolls are available in 5M (≈16.4 ft) or 10M (≈32.8 ft) lengths, and select sizes can be ordered as a 2-pack for projects that need a backup or multiple runs.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include aquarium air and water supply lines, pond pump outlet hoses, home brewing and fermentation transfer tubing, laboratory fluid transfer, small-scale irrigation drip lines, and general-purpose low-pressure water routing in workshops or utility rooms.
