Red silicone rubber tubing is a flexible extruded tube used for compatible air, water, fluid transfer, insulation and equipment connection applications. The red color supports visual identification in assembly and maintenance. Inner diameter, outer diameter, wall thickness, length, Shore A hardness, tolerance, packaging and compliance documentation can be customized according to drawings, samples or application requirements.
Red Silicone Rubber Tubing — Flexible, High-Temperature Silicone Tube for Fluid, Food, and Industrial Use
Red silicone rubber tubing is a flexible, extruded silicone tube used across fluid transfer, food processing, pharmaceutical, and general industrial applications, valued for its high heat resistance and tear resistance. This tubing is typically extruded from a high-strength silicone compound and manufactured across a very wide size range, from fine electrical sleeving diameters up to large-bore industrial tubing.

What Is Red Silicone Rubber Tubing?
Red silicone rubber tubing is a flexible hollow tube extruded from silicone elastomer, commonly used to carry fluids, powders, or protect cables, and post-cured for added stability and heat resistance. It combines high elasticity with strong resistance to ozone, UV exposure, and a wide range of chemicals, making it suitable for both light electrical sleeving and heavier fluid-handling duties. Because silicone remains flexible across a very broad temperature range, this tubing performs reliably in both cold storage and high-heat environments.
Key Properties
- Wide operating temperature range, generally -60°C to +200°C, with certain grades rated higher.
- High elongation of up to 600%, allowing significant stretch without tearing.
- Tear-resistant and highly flexible, suitable for demanding fluid transfer duties.
- Ozone and UV resistant for long service life in exposed environments.
- Good chemical compatibility and strong ageing characteristics.
- FDA-approved and platinum-cured options available for hygiene-critical use.
Material Comparison
| Tubing Type | Temperature Range | Typical Use |
|---|---|---|
| Standard Red Silicone | -60°C to +200°C | General fluid transfer, food, pharma |
| Platinum-Cured Silicone | Similar range, non-yellowing | Medical, high-purity fluid handling |
| High-Temp Silicone (peristaltic grade) | Up to +249°C | Peristaltic pump tubing |
| Red Gum/Natural Rubber Tubing | Lower heat tolerance | Vacuum pump lines, general lab use |
Common Applications
- Food processing and beverage handling lines.
- Pharmaceutical and medical fluid transfer, including catheters and feeding tubes.
- Electrical cable sleeving in confined spaces.
- Aerospace, mass transit, and defense equipment.
- Cardiovascular medical devices simulating arteries and veins.
- General industrial fluid and powder transport.
This wide application range comes from silicone’s combination of flexibility, chemical resistance, and stability across extreme temperatures.
Why Choose Silicone Over Other Rubber Tubing
- Much wider temperature tolerance than standard natural or gum rubber tubing.
- Better resistance to ozone, UV, and outdoor ageing.
- Available in FDA-approved and platinum-cured grades for food and medical use.
- Maintains flexibility and elasticity even after long-term exposure to heat.
- Suitable for both fine electrical sleeving and larger-bore fluid transfer tubing.
Sizing and Selection Guide
Red silicone rubber tubing is manufactured in bore sizes from about 0.2 mm ID up to 200 mm ID, allowing selection of the correct size for the specific application, whether it is fine cable sleeving or larger fluid transfer lines. Wall thickness and hardness (commonly 40, 50, or 60 Shore A) should be selected based on the pressure, flexibility, and durability needs of the application. For hygiene-critical or pharmaceutical use, platinum-cured, non-yellowing tubing is generally recommended over standard peroxide-cured silicone.
Custom Manufacturing Options
- Custom bore ID/OD and wall thickness.
- Standard peroxide-cured or platinum-cured (medical-grade) silicone.
- Shore hardness options: 40A, 50A, 60A.
- FDA, USP Class VI, and BS2848 compliant grades on request.
- Custom cut lengths, coiled reels, or bulk spools.
- OEM branding and private-label packaging.
FAQ
Can red silicone rubber tubing dimensions be customized?
Yes. Red silicone rubber tubing can be customized by inner diameter, outer diameter, wall thickness, cut length and dimensional tolerance. Buyers should provide a drawing, size list or physical sample. Unsupported dimensions should not be assumed because tubing fit and flow performance depend on confirmed size data.
What is red silicone rubber tubing used for?
Red silicone rubber tubing is used for compatible air transfer, water transfer, flexible connection, protective sleeving, insulation and equipment assembly. The specific use depends on the silicone compound, dimensions, wall thickness, media compatibility, temperature, pressure and installation design.
How should buyers select the silicone compound?
Silicone compound selection depends on contact media, operating temperature, pressure or vacuum condition, cleaning process, flexibility requirement and documentation needs. Buyers should provide the actual liquid or gas, exposure time, connector design and application environment before material approval.
Can the tubing be supplied in coils or cut lengths?
Yes. Red silicone rubber tubing can be supplied in coils, cut-to-length pieces or custom packaging formats. The packaging method should match the buyer’s assembly process, warehouse control and distributor requirements. Please provide the required length and packing quantity before quotation.
Are compliance documents available?
FDA, RoHS, REACH and other documentation options are available upon request for applicable silicone compounds. Buyers should specify the required standard, end-use market, contact media and documentation format before quotation, sampling or batch production.
Are samples available before bulk production?
Samples are available upon request. Sample preparation depends on tube size, silicone compound, red color requirement, hardness, tolerance, extrusion die status and packaging method. A drawing, size list or physical sample helps confirm the specification before bulk production.
