Clear Silicone Tubing Food Grade – Flexible Rubber Hose for Water Pump & DIY Plumbing (OD 10–44mm)

Match the OD (outer diameter) to your fitting or barb size. The ID (inner diameter) determines flow capacity — a larger ID allows higher flow rates. For example, if your pump outlet is 10mm, choose a hose with an ID of 10mm. When in doubt, measure your fitting with calipers before ordering. Our size options range from 10×8mm up to 44×38mm to cover most standard pump and plumbing fittings.

Wall thickness varies by size and equals (OD − ID) ÷ 2. For example, the 13×7mm size has a 3mm wall, while the 12×10mm size has a 1mm wall. Thicker walls generally provide greater pressure resistance and durability. Check the variant options for your specific size combination.

Yes. This hose is made from food-grade silicone that is generally non-toxic, odorless, and tasteless. It is typically used in home brewing, winemaking, aquarium water systems, and food processing lines. For commercial food production, always verify compliance with your local food-safety regulations (e.g., FDA, NSF standards).

Food-grade silicone tubing typically withstands temperatures from approximately −60°C (−76°F) to +200°C (+392°F). This makes it suitable for cold-water aquarium systems, hot-wort transfer in home brewing, and general-purpose hot-liquid plumbing. Confirm your specific requirements before use in extreme or sustained high-temperature conditions.

Silicone is generally more UV-resistant than standard rubber or PVC tubing. However, prolonged direct sunlight exposure may cause gradual surface degradation over time. For long-term outdoor installations, consider shielding the hose with conduit or UV-protective wrap to extend service life.

This tubing is compatible with standard barbed fittings, hose clamps, and push-fit connectors sized to match the ID of the hose. It works with most metric and common imperial barb sizes. In most cases, the hose slides snugly onto a barb without tools — secure with a stainless hose clamp for a leak-free seal. Contact us to confirm compatibility with your specific fitting before ordering.

Working pressure varies by wall thickness and diameter. Thicker-walled, smaller-diameter hoses generally handle higher pressures. For typical low-pressure water pump and aquarium applications, this tubing performs reliably. For high-pressure industrial or pneumatic use, please contact us to confirm suitability for your specific size and application.

Yes. Silicone tubing cuts cleanly with sharp scissors or a utility knife — no special tools required. We offer lengths from 1M (≈3.3 ft) to 10M (≈32.8 ft) so you can order the closest standard length to your project needs and trim as required on-site.
