Achieve a permanent, waterproof seal for wire connections with this 1m length of 3:1 heat shrink tubing. The dual-wall construction features an internal adhesive lining that melts to create an airtight, moisture-proof barrier, protecting connections from corrosion, vibration, and environmental damage. It shrinks to one-third its original diameter for a tight, professional fit. Features and Benefits
- 3:1 Shrink Ratio - Provides a tight, secure fit around a wide range of wire and cable diameters, from 1.6mm to 50mm, ensuring no loose sleeves.
- Internal Adhesive Lining - Melts during heating to form a waterproof, dustproof, and strain-relief seal that locks out moisture and secures the connection.
- Polyolefin Outer Wall - Offers excellent abrasion resistance, durability, and protection against common chemicals, oils, and UV exposure.
- 1 Meter Length - Provides ample material for multiple projects or longer cable runs, offering great value and reducing waste from frequent cuts. Applications
- Marine and Automotive Wiring - Ideal for sealing splices and terminations exposed to moisture, fuel, oils, and vibration in harsh environments.
- DIY Electronics and Repairs - Perfect for creating professional, insulated connections on household appliances, robotics, or audio equipment.
- Outdoor and Industrial Equipment - Protects electrical connections in control panels, garden tools, and lighting from weather, dirt, and mechanical stress.
