This 3:1 polyolefin heat shrink tubing provides a durable, insulated seal for wires from 2.4mm to 25.4mm in diameter. The 3:1 shrink ratio ensures a tight, conformal fit, while the flame-retardant polyolefin material offers excellent abrasion resistance and long-term protection against moisture, chemicals, and corrosion. Features and Benefits
- 3:1 High Shrink Ratio - Provides a tight, low-profile seal around irregular shapes and bundles for superior strain relief and environmental sealing.
- Flame-Retardant Polyolefin Construction - Offers reliable protection against abrasion, solvents, and UV exposure while meeting industry safety standards.
- Wide Diameter Range (2.4-25.4mm) - One kit handles a vast array of wire gauges, terminals, and connectors, simplifying inventory.
- Available in 10, 50, and 100 Meter Lengths - Choose the perfect quantity for your project scale, from small repairs to bulk production.
- Standard Black and High-Visibility Red - Black for discrete protection, red for easy circuit identification or safety marking. Applications
- Electrical Repairs and Splicing - Create professional, insulated connections for automotive wiring, appliance cords, and electronic devices.
- Cable Harness Bundling and Protection - Organize loose wires into clean harnesses and shield them from chafing in industrial or vehicle applications.
- Terminal and Connector Insulation - Provide a secure, sealed cover over solder joints, butt connectors, and terminal lugs to prevent shorts.
- DIY and Prototyping - An essential component for hobbyists, makers, and technicians building or repairing electrical projects. Note: Always select a tube diameter approximately one-third the size of the object to be covered for optimal shrinkage and seal. Use a quality heat gun for best results.
