Silicone Tube 30cm - Flexible Heat-Resistant Insulation
Silicone Tube 30cm – Flexible, Heat-Resistant Insulation Sleeve
The Silicone Tube 30cm is a flexible, translucent tubing designed for insulation, protection, and routing in electronics projects. Its high-temperature resistance and durability make it ideal for wire sleeving, 3D printer filament guides, and custom cable management. This tube provides reliable electrical insulation and mechanical protection in cramped enclosures.

- Create a flexible filament guide tube for 3D printer modifications
- Route and bundle sensor wires in custom robotics projects
Compatibility
This tube is non-conductive and compatible with any low-voltage electronics, including Arduino, Raspberry Pi, ESP32, and breadboard projects. It slides over standard 22–26 AWG wires and fits snugly on common header pins for insulation. The silicone material withstands soldering temperatures momentarily without melting.
Wiring Notes
Cut to desired length with scissors or a blade. Before soldering, slide the tube onto the wire and position away from the joint to prevent heat shrinkage. After the joint cools, slide the tube over the connection for a clean, insulated finish. No adhesive or heat shrink is required.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with 3D printer hot ends?
Yes, the 5 mm outer diameter fits standard PTFE tube fittings, and the silicone resists heat up to 200°C, making it suitable for use as a filament guide near the hot end, though not inside the heater block.
Can I use this for drinking water or medical applications?
This tube is food-grade silicone, but we recommend it only for non-critical, dry applications like air or cable routing. For potable water, ensure full sterilization and compliance with local regulations.
Is the tube easy to cut and still flexible after cutting?
Yes, it can be cut cleanly with household scissors. The material remains just as flexible along its entire length, including at the cut ends.
