Food Grade Silicone Tube | Flexible Rubber Water Hose | 0.5mm–25mm ID, Multiple Colors

Measure the outer diameter (OD) of the fitting or pipe stub you need to connect to — that measurement should match the tube's inner diameter (ID). For example, a 10×12mm tube has a 10mm ID and 12mm OD with a 1mm wall. Sizes here range from 0.5×1mm (≈0.02" ID) up to 25×31mm (≈0.98" ID). When in doubt, size up slightly — a marginally larger ID is easier to work with than one that's too tight. You can also add a hose clamp for a more secure fit on barb fittings.

Silicone tubing generally withstands temperatures from approximately -60°C (-76°F) to +200°C (+392°F). It stays flexible at freezing temperatures and does not soften or deform at typical hot-water or steam temperatures encountered in home plumbing and lab applications. For sustained high-pressure steam, contact us to confirm suitability.

Yes. This is food-grade silicone tubing — it is odorless, tasteless, and does not leach plasticizers or other chemicals into the fluid. It is widely used in homebrewing, aquariums, and food processing lines. It is not made from PVC and contains no phthalates.

Yes. Silicone is inherently resistant to UV radiation, ozone, and moisture. Unlike standard rubber or PVC hose, it will not crack, harden, or discolor with prolonged outdoor exposure. It is a solid choice for garden irrigation connections, outdoor aquaponics systems, and any exterior plumbing run where a flexible rubber water pipe is needed.

This silicone hose for water is compatible with potable water, air, steam, most dilute acids and bases, and food-grade liquids including beer, wine, juice, and dairy. It is generally not recommended for concentrated solvents (acetone, toluene), fuels, or strong oxidizing agents. Contact us to confirm compatibility with any specific chemical before use.

Silicone is flexible and stretches slightly, so it typically slides directly onto standard barb fittings. For a secure seal, choose a barb OD that matches or is 1–2mm larger than the tube's ID. For higher-pressure applications, add a stainless steel hose clamp over the connection point. No adhesive or thread sealant is needed for standard barb connections.

Measure your intended run and add 10–15% for routing curves and connections. 1 M (≈3.3 ft) suits most single aquarium or appliance connections. 2 M (≈6.6 ft) works well for lab bench setups or multi-device runs. 5 M (≈16.4 ft) is ideal for larger aquaponics systems, homebrewing rigs, or when you want spare length on hand for future modifications.
