Match the inner diameter (ID) to your fitting or barb size. For example, a 1/4" (≈6mm) barb fitting typically pairs with a 6mm ID tube. Always measure your fitting OD first, then select the ID that creates a snug, leak-free seal. The outer diameter (OD) determines wall thickness — a thicker wall generally means higher pressure tolerance. Common conversions: 6mm ≈ 1/4", 8mm ≈ 5/16", 10mm ≈ 3/8", 12mm ≈ 1/2", 19mm ≈ 3/4".

Food grade silicone tubing of this type can typically handle working pressures of 30–100 PSI depending on wall thickness and diameter. Smaller diameters with thicker walls generally support higher pressures. For high-pressure applications, contact us to confirm the specific variant's rating before ordering.

Yes. Silicone is generally rated for continuous use from -60°C to +200°C (-76°F to +392°F), making it suitable for outdoor installations, steam lines, and high-temperature brewing processes. UV resistance is generally good, though prolonged direct sunlight exposure over many years may cause minor surface changes. For outdoor use, routing through conduit or shading the hose is a good practice.

Yes. The inner diameter (ID) is designed to fit standard barb fittings. For example, 6mm ID fits 1/4" barbs, 8mm ID fits 5/16" barbs, and 10mm ID fits 3/8" barbs. Worm-drive or spring hose clamps can be used for a secure, leak-free connection. Always verify the barb OD matches the tube ID before ordering.

Yes. This tubing is made from food grade silicone that is generally compliant with FDA 21 CFR 177.2600 standards for repeated food contact. It is odorless, tasteless, and non-toxic, making it suitable for beer brewing transfer lines, winemaking, milk and dairy systems, and potable water routing in RV, marine, and home plumbing applications.

Measure the total run from your source to destination, then add 10–15% extra for routing around obstacles and making connections. For a typical homebrew setup, 1–3m is usually sufficient for a single vessel connection. Longer runs of 5–15m are suited for multi-vessel brewing systems, dairy equipment, or industrial fluid transfer lines where continuous runs are needed.

Yes. Silicone tubing cuts cleanly with a sharp utility knife or scissors. A straight, clean cut ensures a better seal on barb fittings. For larger diameters (12mm ID and above), a tube cutter or a cutting guide helps ensure a perpendicular cut for the best fit.

Silicone tubing is one of the most common materials used in peristaltic pumps due to its flexibility, resilience, and food-safe properties. In most cases, the tube ID and wall thickness must match your pump head specifications. Contact us with your pump model details and we can help confirm compatibility.
