How do I choose the right size silicone tube?

Measure the outer diameter (OD) of the fitting or barb you need to connect to — that should match the tube's inner diameter (ID). For example, a 1/4" (6mm) barb fitting typically pairs with an ID 6mm tube. Always check both ID and OD to ensure a snug, leak-free fit.

What temperature range can this silicone tube handle?

This silicone tubing is generally rated for continuous use from approximately -60°C to +200°C (-76°F to +392°F), making it suitable for both cold and high-temperature applications such as brewing, autoclaving, and hot liquid transfer.

Is this tubing safe for food and beverage contact?

Yes. This tube is made from food-grade silicone that is typically odorless, tasteless, and non-toxic. It is generally compliant with FDA food-contact standards, making it suitable for homebrewing, winemaking, aquariums, and drinking water systems.

Can I use this silicone hose outdoors or in UV-exposed environments?

Silicone is generally more UV-resistant than standard rubber or PVC tubing. For prolonged outdoor exposure, the transparent variant may yellow slightly over time, while opaque colors tend to hold up better. For critical outdoor installations, additional UV shielding is recommended.

How do I select the right length — 1 meter, 10 meters, or 20 meters?

For single-run connections (e.g., connecting a tap to a keg), 1 meter is typically sufficient. For longer plumbing runs, aquarium setups, or workshop installations, 10 or 20 meter rolls offer better value. Add 10–15% extra to your measured run to account for bends and connections.

Food Grade Silicone Tube — Flexible, High-Temp Rubber Hose for Brewing, Lab & DIY

Whether you're routing liquid through a homebrewing setup, building an aquarium filtration system, or plumbing a DIY food-processing rig, finding tubing that won't leach chemicals, crack under heat, or kink mid-run is a constant headache. This food grade silicone tube is built for exactly those situations — delivering clean, reliable flow without the compromises of PVC or standard rubber hose.

Each order is cut from a continuous silicone extrusion in your chosen color and length (1 meter, 10 meters, or 20 meters). Inner diameters range from 2mm (≈5/64") to 14mm (≈35/64"), with outer diameters from 4mm (≈5/32") to 18mm (≈45/64") — covering the most common barb and fitting sizes used in brewing, laboratory, aquarium, and light industrial applications. Wall thickness varies by size; see the size selector for exact ID × OD pairings. Available in 16 colors including transparent, black, red, white, and a full spectrum of vivid options for color-coded line identification.

Typical use cases include homebrewing and winemaking transfer lines, aquarium pump and filter hose, laboratory peristaltic pump tubing, food-processing equipment connections, and DIY cooling or heating loops where a flexible high-temp rubber hose rated to approximately 200°C (392°F) is required.

✅ Compatibility note: Select the tube size whose inner diameter (ID) matches the outer diameter of your barb fitting or nozzle. Standard metric barb sizes (M4–M14) and common imperial equivalents (3/16", 1/4", 5/16", 3/8", 1/2") are covered across the available size range. Confirm your fitting OD before ordering.

⚠️ Size tip: If you are unsure of your fitting size, measure the barb OD with calipers and match it to the tube ID listed in the variant selector. A snug interference fit is normal for silicone — the tube will stretch slightly over the barb for a leak-resistant seal.

✅ Key Features of These Food Grade Silicone Tubes

🌡️Wide Temperature Range — Rated for continuous service from approximately -60°C to +200°C (-76°F to +392°F), making this flexible high-temp rubber hose suitable for hot-side brewing transfers, autoclaving, and cold-side chilling lines.
🍺Food-Safe Material — Manufactured from food grade silicone that is odorless, tasteless, and non-toxic, meeting general FDA food-contact guidelines for use in homebrewing, winemaking, and drinking water systems.
🎨16 Colors for Easy Line ID — Choose from transparent, black, red, white, yellow, navy blue, sky blue, bright green, orange, purple, pink, green, transparent red, orange red, blue, and bright orange to color-code your plumbing runs at a glance.
📏13 Size Options — ID × OD combinations from 2×4mm up to 14×18mm cover the most common barb fitting sizes used in aquarium pump hose, laboratory peristaltic pump tubing, and DIY fluid systems.
🔄Kink-Resistant Flexibility — The soft, elastic silicone wall bends around tight corners without collapsing the bore, maintaining consistent flow even in confined installations.
✂️Cut-to-Length Rolls — Available in 1m, 10m, and 20m lengths so you can order exactly what your project needs — no waste, no splicing short pieces together for longer runs.

❓ Frequently Asked Questions

How do I choose the right silicone tube size?

Measure the outer diameter (OD) of the barb fitting or nozzle you need to connect to — that measurement should match the tube's inner diameter (ID). For example, a 6mm (≈1/4") barb pairs with an ID 6mm tube. Always verify both ID and OD before ordering. A snug fit is normal; silicone stretches slightly over barbs for a leak-resistant seal.

What is the maximum temperature this silicone hose can handle?

This food grade silicone tube is generally rated for continuous service up to approximately 200°C (392°F) and down to -60°C (-76°F). It is typically suitable for hot-side brewing transfers, steam-adjacent applications, and autoclave-adjacent uses. For sustained exposure above 180°C, contact us to confirm suitability for your specific application.

Is this tubing safe for drinking water, beer, and wine contact?

Yes. The tubing is made from food-grade silicone that is generally odorless, tasteless, and non-toxic. It is widely used in homebrewing, winemaking, kombucha brewing, and drinking water systems. It does not impart flavor or odor to liquids under normal use conditions.

Can I use this silicone tube outdoors or in UV-exposed areas?

Silicone is generally more UV-resistant than PVC or standard rubber. Opaque colors (black, red, white, etc.) tend to hold up better under prolonged UV exposure than the transparent variant, which may yellow slightly over time. For critical long-term outdoor installations, additional UV shielding or conduit is recommended.

What fittings are compatible with this silicone tubing?

This tubing is compatible with standard barb fittings, hose clamps, and push-fit connectors sized to match the tube's inner diameter. It works with metric barb sizes (M4 through M14) and common imperial equivalents (3/16", 1/4", 5/16", 3/8", 1/2"). Always confirm the barb OD matches the tube ID for a secure, leak-free connection.

How do I choose between 1 meter, 10 meters, and 20 meters?

For a single short connection (e.g., tap to keg, pump to filter), 1 meter is typically sufficient. For longer plumbing runs, aquarium setups, or workshop installations where you need multiple cuts, 10m or 20m rolls offer significantly better value per meter. As a rule of thumb, add 10–15% to your measured run length to account for bends, fittings, and trimming.

Does wall thickness affect pressure rating or kink resistance?

Yes. A thicker wall (larger OD relative to ID) generally provides better burst pressure resistance and kink resistance. For gravity-fed or low-pressure systems, thinner-walled sizes work well. For pump-driven or pressurized systems, choose a size with a proportionally larger wall thickness. Contact us to confirm pressure ratings for your specific size and application.

How do I clean and sterilize this silicone tubing?

Silicone tubing is generally compatible with common sanitizers used in homebrewing (Star San, iodophor) and can typically withstand boiling water for sterilization. It is also generally dishwasher-safe at standard temperatures. Avoid prolonged contact with concentrated solvents or strong oxidizing agents unless you have confirmed chemical compatibility.
