3:1 Adhesive Lined Heavy Wall Heat Shrink Tubing Features
- Sold in 4-foot sticks for efficient handling and consistent installation
- 3:1 shrink ratio for easy installation over large connectors and irregular shapes
- Heavy-wall polyolefin exterior offers strong abrasion and impact resistance
- EVA adhesive lining delivers a secure, waterproof, and moisture-tight seal
- Excellent electrical insulation for reliable cable and splice protection
- Operating temperature: -55℃ to 110℃ (-67°F to 230°F)
- Minimum shrink temperature: 80℃ (176°F)
- Durable, long-term environmental protection for indoor and outdoor use
- RoHS compliant
- Material: Polyolefin outer jacket with EVA adhesive inner layer
The Kable Kontrol® 3:1 Heavy Wall Adhesive Lined Heat Shrink Tubing is built for applications where maximum protection and a fully sealed connection are essential. Designed with a rugged polyolefin outer layer and an inner EVA adhesive lining, this tubing delivers a dependable moisture-tight bond that shields electrical splices, joints, and terminations from harsh environmental conditions. Once heated, the 3:1 shrink ratio allows the tubing to conform tightly around oversized connectors and uneven shapes, creating a secure and long-lasting seal. Its heavy-wall construction provides strong resistance against abrasion, impact, and mechanical wear, while also offering excellent electrical insulation. With an operating range of –55°C to 110°C (-67°F to 230°F) and a low minimum shrink temperature of 80℃ (176°F), it performs reliably in both indoor and outdoor environments. Supplied in convenient 4-foot sticks and compliant with RoHS standards, this tubing offers a durable, professional-grade solution for protecting and sealing electrical connections.
Common Uses
- Sealing and protecting electrical splices and terminations
- Providing waterproof protection for outdoor and underground cable joints
- Repairing and reinforcing damaged or worn cable jackets
- Insulating automotive, marine, and industrial wiring
- Protecting battery cables, power supply leads, and control wiring
- Shielding connections from corrosion, vibration, and mechanical stress
- Creating durable seals on heat-sensitive or irregular-shaped components
