Food Grade Clear Silicone Tubing — Flexible Rubber Hose Pipe ID 0.33mm–50mm

Measure the outer diameter (OD) of the fitting or nipple the tube will slip over — that becomes your required ID. For example, a 6mm barb fitting typically needs a 6mm ID tube. Wall thickness (OD minus ID, divided by 2) affects flexibility and pressure rating: thinner walls are more flexible, thicker walls handle higher pressure. All sizes on this page are listed as ID × OD in millimeters. A quick inch reference: 6mm ≈ 1/4", 10mm ≈ 3/8", 12mm ≈ 1/2", 25mm ≈ 1".

Working pressure varies by wall thickness and bore diameter. Smaller-diameter tubes with thicker walls generally handle higher pressures — typically in the range of 30–150 PSI for standard wall thicknesses. For high-pressure applications such as pneumatic lines or pressurized brewing systems, please contact us to confirm the specific variant's rating before ordering.

Yes. Silicone is inherently UV-resistant and does not degrade from sun exposure the way rubber or PVC does. It generally withstands continuous temperatures from approximately –60°C (–76°F) to 200°C (392°F), making it suitable for outdoor plumbing, engine cooling overflow lines, greenhouse irrigation, and food processing equipment near steam or hot water.

This tubing is made from food grade silicone that is odorless, tasteless, and non-toxic. It is commonly used for milk lines, homebrew beer and wine transfers, aquarium water lines, and laboratory fluid handling. If your application requires a specific FDA or NSF certification document, please contact us to confirm compliance for your chosen variant.

Sizes up to 38mm × 44mm are standard round-profile tubes. Sizes listed as Flat Shape (40mm × 48mm and larger) have a flattened cross-section when not under pressure, which makes them easier to coil, store, and ship. They expand to a full round profile when fluid flows through them, functioning identically to round-profile hose in use.

The ID dimension is the key measurement for barb fitting compatibility. A tube with a 6mm ID will generally fit a 6mm barb fitting with a snug, leak-resistant seal — silicone's elasticity helps it grip the barb securely. For push-to-connect fittings, match the tube's OD to the fitting's stated tube OD. If you are unsure, contact us with your fitting specs and we can help you select the correct size.

Yes. Silicone tubing cuts cleanly and squarely with sharp scissors or a utility knife — no special tools required. We offer 1-meter, 5-meter, and 10-meter lengths so you can order the quantity closest to your project needs and trim to fit on-site. Cuts are clean enough to seat directly onto barb fittings without fraying.
