【Emergency Freeze Protection Up to -40°F】Prevents ice blockages in water-filled metal/plastic pipes (copper, PVC, PEX) even at -40°F. Pure copper core maintains pipe temperatures 10-15°F above ambient to avoid bursts. Warning: Never use on fuel lines or gutters—lack of water causes overheating. 【Industrial-Grade Multi-Layer Armor】 Exceeds standard tapes with 3-layer defense: → Oxygen-free copper core (99.99% conductivity) → Explosion-proof aluminum shield (physical impact resistance) → IP67 TPE jacket (resists UV/chemicals/salt corrosion) Proven 20-year lifespan in coastal/buried pipes. 【UL Full-Cable Certified Safety + $1M Insurance】Entire cable (not just plug!) meets UL fire/electrical standards. Aluminum-magnesium alloy layer (70% coverage) prevents short circuits. Includes 5FT grounded plug with indicator light + product liability insurance. 【Universal Pipe Compatibility + Length Flexibility】Works on all metal/plastic pipes (copper, PVC, stainless steel). Available from 3FT to 200FT—choose exact length for residential roofs or industrial pipelines. Installs straight, spiral, or overlapped. 【24/7 Support & Hassle-Free Warranty】30-day returns + 1-year warranty. Email installation photos for custom layout review within 4 hours. Free compliance docs + same-day replacements if damaged during install. Our products prevent ice dams from forming on roofs, keep pipes from freezing and keep water flowing, making them a must-have for your winter home travels and DIY for any location that needs heating. Because the inside is copper wire and conductor, and there is current, when using it, be careful not to twist, pull, fold, cut and other destructive actions.
