5mm x 8mm Food Grade Color Silicone Tube Flexible Tubing Hose Pipe Soft Rubber

This tubing has a 5mm inner diameter, so it fits barb fittings with a 5mm (approximately 3/16") barb OD. Always measure your fitting's barb diameter before ordering to ensure a snug, leak-free connection.

Yes. The tubing is made from food-grade silicone, which is free from BPA, phthalates, and plasticizers. It does not impart taste or odor to liquids, making it suitable for brewing, beverage dispensing, and food processing lines. If you require documentation for a specific regulatory standard, please contact us to confirm.

Silicone tubing is rated for continuous use up to approximately 200°C (392°F), so it handles hot water, wort, and low-pressure steam without softening or deforming. For sustained high-pressure steam applications, verify the pressure rating with us before use.

The soft silicone wall is designed to flex without collapsing the bore. For tight bends, use a bend radius of at least 2–3× the outer diameter (16–24mm) to maintain full flow. Avoid sharp 90° bends without a support elbow if consistent flow rate is critical.

Color choice is purely functional — all colors share the same silicone compound and dimensions. Use different colors to distinguish fluid types (e.g., blue for water, red for a return line, transparent for visual flow monitoring). Transparent is also useful when you need to visually confirm liquid is flowing.

Silicone has good resistance to dilute acids, alkalis, and UV radiation, making it more durable outdoors than PVC or rubber alternatives. It is not recommended for concentrated solvents, fuels, or strong oxidizing agents. If your application involves aggressive chemicals, contact us with the specific substance for compatibility confirmation.

Yes. Silicone tubing cuts cleanly with sharp scissors or a utility knife. Select the next length up from what you need and trim to fit. The cut ends remain smooth and seal well against barb fittings without fraying.
