Product Details

✓Ultimate Waterproof Seal & 3:1 Shrinkage: Get a perfect, air-tight seal with the superior 3:1 shrink ratio, shrinking to 1/3 of the original size. This eliminates the loose fit common with 2:1 tubing, providing a strong, non-slip grip that protects electrical connections from water, dust, and moisture instantly.
✓Dual Wall Adhesive Lined Protection: Our tubing features dual-wall construction; the flexible outer wall provides high abrasion resistance and flame retardant safety, while the inner adhesive lining melts to create a 360° waterproof, oil-proof, and corrosion-resistant seal upon cooling.
✓Industrial and Marine Grade Durability: Designed to perform in harsh environments (Automotive, Boat, Outdoor, and Industrial). This tubing has high tensile strength and excellent high-temperature resistance (up to 125°C), ensuring your wire connections are more durable and long-lasting than the wire itself.
✓Flexible, Easy to Use Insulation: Simply cut to the needed size, slide it over the wire/joint, and apply heat. This thick-walled tube provides reliable electrical insulation and strong strain relief, making professional-grade connections in seconds for solder joints, wire ends, and harnesses.
✓Compact and Economical 10ft Roll: This convenient 10ft roll offers an economical supply perfect for quick repairs, small DIY projects, and custom wire runs, suitable for wire sizes up to 5/16" 8mm. Minimize waste and maximize value with this essential tool.
