Food Grade Silicone Tubing — Flexible Clear & Colored Rubber Hose, I.D. 0.5–25 mm, Cut to Length

Measure the outer diameter of the fitting or barb the tube will slip over — that becomes your I.D. (inner diameter). For example, a 6 mm barb typically needs a 6 mm I.D. tube. Wall thickness determines pressure rating; thicker walls generally handle higher pressure. All sizes on this listing are expressed as I.D. × O.D. in mm. To convert: 1 inch = 25.4 mm, so a 1/4" barb ≈ 6.35 mm — the 6×8 mm or 6×9 mm variant would typically be the closest fit.

Working pressure varies by wall thickness and diameter. Smaller-diameter tubes with thicker walls generally handle higher pressures — typically in the range of 30–100 PSI for standard silicone tubing. For high-pressure applications such as compressed air lines, please contact us to confirm the specific variant's rating before ordering.

Yes. This tubing is made from food-grade silicone that is generally non-toxic, odor-free, and taste-neutral. It is commonly used in homebrewing, winemaking, beverage dispensing, and food processing transfer lines. Always verify compliance with your local food-safety regulations for commercial applications.

Yes. Silicone tubing is inherently UV-resistant and typically rated for continuous use from -60°C to +200°C (-76°F to +392°F), making it suitable for outdoor plumbing, engine cooling overflow lines, and oven ventilation. Unlike PVC hose, it will not crack, harden, or become brittle with prolonged sun or heat exposure.

This flexible silicone rubber hose fits standard barbed fittings, hose connectors, and push-fit adapters sized to match the tube's I.D. It is compatible with metric barbs (e.g., 4 mm, 6 mm, 8 mm, 10 mm) and generally works with common US fractional sizes when the barb O.D. matches the tube I.D. No special tools are needed — the flexible silicone stretches slightly for a secure, leak-resistant grip on the barb.

A sharp utility knife or scissors will produce a clean, square cut. We ship the tubing cut to your selected length in 1 m increments. If you need a length between increments, order the next size up and trim to fit. The cut end remains smooth and does not fray.

No. The colorants used in food-grade silicone tubing are generally inert and do not leach into fluids under normal operating conditions. Color is purely cosmetic and is commonly used for color-coding different lines in lab setups, brewing manifolds, or aquarium systems to quickly identify which line carries which fluid.
