Translucent Silicone Tube — Flexible Industrial Rubber Hose for Fluid, Air & Lab Applications
When standard PVC or rubber tubing cracks under heat, stiffens in the cold, or contaminates the media it carries, engineers, lab technicians, and DIY builders reach for silicone. Whether you're routing coolant through a custom PC loop, plumbing a homebrewing system, or building a peristaltic pump, finding a translucent silicone tube in exactly the right inner diameter and wall thickness — without buying a full industrial spool — is the real challenge.
This listing offers industrial-grade translucent silicone rubber tubing available in inner diameters from 2mm (≈5/64") to 70mm (≈2-3/4"), with outer diameters sized to give wall thicknesses typically ranging from 1mm to 5mm depending on the variant. Length options include 1 Meter (≈3.3 ft), 2 Meter (≈6.6 ft), 5 Meter (≈16.4 ft), 10 Meter (≈32.8 ft), and 20 Meter (≈65.6 ft) — select the combination that fits your project from the variant dropdowns above.
Typical use cases include laboratory peristaltic pump tubing, aquarium and fish tank air lines, homebrewing and winemaking transfer hoses, automotive coolant overflow lines, food-processing fluid transfer, and general-purpose industrial soft pipe routing where flexibility and visual flow monitoring are required.
🔗
Compatibility: Fits standard barb fittings, hose clamps, and push-to-connect connectors. Match the fitting's barb OD to the tube's Inner Diameter (ID) for a secure, leak-resistant seal. Works with brass, stainless steel, and plastic fittings.
⚠️
Size confirmation: Inner Diameter (ID) and Outer Diameter (OD) are listed in each variant name. Wall thickness = (OD − ID) ÷ 2. If you are unsure which size fits your fitting, measure the barb OD and select the matching ID. Contact us before ordering if you need to confirm pressure ratings or material certifications.
✅ Key Features of These Translucent Silicone Rubber Tubes
-
🌡️Wide Temperature Tolerance — Silicone rubber generally maintains flexibility from approximately -60°C (-76°F) to +200°C (+392°F), making this soft pipe suitable for both cryogenic and high-heat industrial fluid transfer applications.
-
👁️Translucent Wall for Flow Monitoring — The clear silicone construction lets you visually confirm fluid flow, detect air bubbles, and spot blockages without disconnecting the line — a practical advantage in lab and brewing setups.
-
🔄Flexible & Kink-Resistant — The soft rubber compound bends around tight corners without collapsing, reducing the need for rigid elbows or fittings in compact installations like aquarium sumps or custom cooling loops.
-
⚗️Chemically Inert Construction — Silicone is resistant to ozone, UV, and many dilute acids and bases, making this industrial-grade rubber hose a reliable choice for laboratory fluid handling and chemical transfer at low concentrations.
-
📏Broad Size Range in One Listing — With ID options from 2mm to 70mm and lengths from 1 to 20 meters, this single product covers everything from micro-dosing pump tubing to large-bore industrial soft pipe without sourcing from multiple suppliers.
-
🍺Food-Contact Grade Material — The silicone compound used is generally suitable for food, beverage, and pharmaceutical fluid transfer. Confirm certification requirements with us if your application demands documented food-grade or USP Class VI compliance.

❓ Frequently Asked Questions
How do I choose the right inner diameter and length for my application?
Measure the outer diameter of the fitting or barb the tube will slip over — that measurement should match the tube's inner diameter (ID). For length, add 10–15% to your measured run to allow for routing and connections. For example, if you need tubing for a 6mm barb fitting, select ID 6mm and your preferred length. If you're between sizes, size up for a snug fit over the barb.
What temperature range can this silicone tubing handle?
Silicone tubing of this type generally withstands temperatures from approximately -60°C (-76°F) to +200°C (+392°F). This makes it suitable for most industrial, laboratory, and food-processing environments. Continuous exposure near the upper limit may reduce service life over time; for sustained high-heat applications, confirm the specific grade with us.
Is this tubing safe for food, beverage, or pharmaceutical use?
Translucent silicone tubing of this grade is typically manufactured from silicone compound that meets FDA 21 CFR 177.2600 requirements for food contact. If your application requires certified food-grade or USP Class VI compliance with documentation, please contact us to confirm the specific batch certification before ordering.
Can I use this silicone hose outdoors or in UV-exposed environments?
Silicone is generally more UV-resistant than standard rubber or PVC tubing and performs well in outdoor settings. Prolonged direct UV exposure over many years may cause slight surface degradation. For long-term outdoor installations, shielding the tubing from direct sunlight is recommended to maximize service life.
What fittings or connectors are compatible with this tubing?
This tubing is compatible with standard barb fittings, hose clamps, and push-to-connect connectors sized to match the inner diameter. It works with brass, stainless steel, and plastic barb fittings. No special thread standard is required — simply match the barb OD to the tube ID for a secure, leak-resistant connection. Hose clamps are recommended for pressurized applications.
How do I calculate the wall thickness from the ID and OD listed in the variant name?
Wall thickness = (OD − ID) ÷ 2. For example, ID 6mm × OD 10mm gives a wall thickness of (10 − 6) ÷ 2 = 2mm. Thicker walls generally provide higher pressure tolerance and greater kink resistance. If you need a specific wall thickness for a pump or pressure application, use this formula to select the right variant.
What is the typical working pressure for this silicone tubing?
Working pressure varies by wall thickness and diameter. Smaller-diameter tubes with thicker walls typically handle higher pressures. In most cases, silicone tubing of this type is rated for low-to-medium pressure applications (generally under 0.3–0.8 MPa at room temperature). Contact us to confirm pressure ratings for your specific ID/OD combination before use in pressurized systems.
