【5W/FT High-Density Heating with Copper Core】Oxygen-free copper (99.99% conductivity) delivers rapid thermal response, maintaining pipes 10-15°F above ambient in temperatures down to -40°F. Prevents energy waste while stopping ice blockages in water-filled pipes. 【End-to-End UL Certification + Safety Engineering】 Full-cable UL tested —unlike plug-only certified competitors. Features: → Aluminum-magnesium alloy shielding (70% coverage) → Flame-retardant TPE jacket (IP67 rated for moisture/chemicals) 【Custom Lengths (3FT-200FT) + Multi-Scene Installation】 Deploy straight, spiral, or overlapped on any pipe path. Pre-installed mounting buckles simplify DIY setup—ideal for residential gutters or industrial plant pipelines. 【Strict Compliance: Metal/Plastic Pipes Only】Compatible with copper/PVC/stainless steel. Critical: Do NOT use on empty pipes, fuel lines. Water heat dissipation prevents overheating risks. 【Engineer-Backed Support + Commercial Warranty】24/7 US technical team provides pipe layout reviews via photo submission. Includes reports for businesses + 1-year no-questions-asked warranty with same-day replacements. 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.
