Clear Silicone Capillary Tube — Flexible Food-Grade Hose for Homebrewing, Lab & Precision Fluid Transfer

Homebrewers, lab technicians, and DIY fluid-system builders all share the same frustration: generic PVC or rubber tubing that kinks, clouds up, imparts off-flavors, or cracks after a few heat cycles. Whether you're siphoning a batch of homebrew, routing reagents through a peristaltic pump, or building a precision capillary flow system, you need tubing that stays clear, stays flexible, and stays inert — every time.

This clear silicone capillary tube is made from food-grade silicone elastomer. Each roll is sold by the meter in lengths of 5, 10, 20, 25, 50, or 100 meters. Inner diameters range from 0.5mm (≈0.020") to 5mm (≈0.197"), with outer diameters ranging from 1mm up to 7.5mm depending on the variant — giving you precise wall-thickness control for your application. The tubing is optically clear, allowing visual flow monitoring without cutting into the line.

Typical use cases include homebrewing siphon and transfer lines, laboratory capillary flow systems, peristaltic pump tubing for food or chemical dosing, medical device prototyping, aquarium CO₂ diffuser lines, and precision ink or dye delivery in industrial equipment. The small-bore variants (ID 0.5–1mm) are especially popular for capillary chromatography setups and micro-dosing rigs.

✅ Compatibility: Fits standard barb fittings matched to the selected ID. Not pre-cut — arrives as a continuous roll. Compatible with peristaltic pumps, gravity siphons, aquarium CO₂ systems, and lab fluid circuits. Confirm your fitting barb OD matches the tube ID before ordering.

✅ Key Features of These Clear Silicone Capillary Tubes

🧪Food-Grade Silicone Material — Non-toxic, odorless, and tasteless silicone that won't leach plasticizers or impart off-flavors into beer, wine, juice, or other food-contact fluids.
🔍Optically Clear Wall — Transparent tubing lets you visually monitor flow, detect air bubbles, and confirm fluid color without interrupting the line — critical for homebrewing and lab capillary tube applications.
🌡️Wide Temperature Tolerance — Typically rated from -60°C to +200°C (-76°F to +392°F), handling both cold-side transfers and hot-side sanitation cycles without cracking or deforming.
📏Precision Bore Sizing — Available in 47 ID × OD combinations from 0.5mm to 5mm ID, letting you match exact fitting barb sizes for leak-free connections in peristaltic pump tubing and micro-flow systems.
🔄Flexible & Kink-Resistant — Soft silicone elastomer bends around tight corners without collapsing the bore, maintaining consistent flow rates in aquarium CO₂ lines, dosing systems, and routed lab setups.
📦Bulk Roll Options — Choose from 5, 10, 20, 25, 50, or 100-meter rolls to minimize waste and reduce per-meter cost for larger installations or ongoing production use.

❓ Frequently Asked Questions

How do I choose the right inner diameter and length for my application?

Match the ID to your fitting or barb size — the tube should slip snugly over the barb without forcing. For homebrewing siphon lines, ID 3/16" (≈4.8mm) is common; for capillary or lab work, ID 0.5–1mm is typical. For length, measure your run and add 10–15% for routing. Available in 5, 10, 20, 25, 50, and 100-meter rolls.

Is this tubing safe for contact with food and beverages?

Yes. This tubing is made from food-grade silicone that is generally non-toxic, odorless, and tasteless. It does not leach plasticizers or impart flavor, making it suitable for beer, wine, juice, and other food-contact applications.

What temperature range can this silicone tubing handle?

Silicone tubing of this type typically handles continuous service from approximately −60°C to +200°C (−76°F to +392°F), making it suitable for both cold-side and hot-side brewing processes, as well as autoclave sterilization in lab settings.

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

Silicone generally has good UV and ozone resistance compared to rubber or PVC. For prolonged outdoor UV exposure, shielding is still recommended to maximize service life, but short-term outdoor use is generally fine.

What fittings or connectors are compatible with this tubing?

This tubing is compatible with standard barb fittings sized to match the ID. For example, ID 1mm tubing fits 1mm barbs; ID 3mm fits 3mm barbs. It is not threaded and does not use NPT or BSP connections directly — use a barb-to-thread adapter if needed.

How do I cut the tubing to length?

A sharp utility knife or scissors gives a clean, square cut. For very small diameters (ID 0.5–1mm), a razor blade or scalpel is recommended to avoid crushing the bore. No special tools are required.

How do I select between the different outer diameter options for the same inner diameter?

The difference between ID and OD determines wall thickness. A thicker wall (larger OD relative to ID) provides more pressure resistance and kink resistance. For low-pressure gravity-fed applications, a thinner wall is fine. For peristaltic pumps or pressurized lines, choose a thicker wall variant.

These o rings are a great for my ear tunnels

These o rings are a great for my ear tunnels, always loosing one here and there, I always have a new ones in the drawer. Being silicone, don't have any reactions compared to standard rubber ones I purchased at hardware stores, plus much less expensive. Purchased 16mm I'd to use on 19mm tunnels, and stay on great, might be able to get away with 17mm rings, but really happy with my choice.

Will never order from these folks again

I waited a long time and that’s all I received was the eyebolt with no threaded rod attached to it

Perfect they are really made well and I used them for my car

Perfect they are really made well and I used them for my car. The only thing I had a great for us. It took three weeks to get here. So shipping was slow.

did not include wing nuts
