MAXKOSKO 12V DC Self-Regulating Heating Cable, 5W/ft Low Voltage Pipe Heat Tape for RV, Boat & Off-Grid Water Lines

12V DC Cut-to-Length Self-Regulating Pipe Heating Cable MAXKOSKO 12V DC Pipe Heating Cable provides low-voltage freeze protection for RVs, campers, boats, battery-powered plumbing, off-grid water systems, and other locations where 120V household power is unavailable. The cable delivers approximately 5W/ft at 50°F (10°C), automatically adjusts its heat output according to temperature, and can be trimmed to the required length when the cut end is properly sealed with the included waterproof end-seal kit. 12V DC Low Voltage Designed for compatible 12V batteries, DC power systems, RVs, boats, and off-grid installations. Cut-to-Length Design Trim the heating cable to the required pipe length and reseal the cut end using the included waterproof end-seal kit. Self-Regulating Heat Produces more heat in colder conditions and reduces output as pipe temperature rises. 3 ft Cold Lead Provides a separate non-heating lead for connection to the compatible 12V DC power system. Important Before Ordering 12V DC Power Only Do Not Connect to 120V AC: This cable is designed only for compatible 12V DC electrical systems. Connecting it to household voltage will damage the product and create a serious safety hazard. Power Source Not Included: A 12V battery, DC power supply, switch, fuse, wiring, and battery-management equipment are not included. 120V Controller Is Not Compatible: Do not use the MAXKOSKO 120V Thermostat Controller with this product. Calculate Electrical Load: Confirm the selected cable length, total current demand, fuse rating, wire gauge, battery capacity, and expected operating time before installation. Self-Regulating Is Not Auto-Off: The cable adjusts heat output but does not completely shut itself off. Use a compatible 12V switch, thermostat, relay, or power-management system. Seal Every Cut End: Never energize the cable after cutting until the exposed end has been completely sealed with the supplied waterproof end-seal components. Pipe Insulation Required: Cover the pipe and cable with suitable insulation after installation to improve freeze protection and reduce battery use. 12V DC or 120V AC? Choose 12V DC Best for RVs, boats, trailers, batteries, solar systems, mobile plumbing, and remote installations without household power. Choose Blue 120V Best for household outlets when you want a built-in automatic thermostat. View Blue 120V Cable Choose Green 120V Best for household outlets when you want continuous operation or a separate adjustable controller. View Green 120V Cable Choose Dual-LED 120V Best when you want a built-in thermostat with separate power and active-heating indicators.

Route the cable in a straight line, spiral pattern, or approved overlapping configuration. Secure the cable approximately every 12 inches using aluminum foil tape or suitable ties. Cut the cable only at the required end location. Install the waterproof end seal completely before connecting power. Cover the pipe and cable with suitable insulation. Connect the red and black leads to the correct 12V DC polarity. Install appropriate fuse and overcurrent protection for the selected cable length. Test the complete system before winter use. Frequently Asked Questions Can this cable plug into a household outlet? No. It operates only on 12V DC and must never be connected to a 120V AC household outlet. Can I use the MAXKOSKO 120V thermostat controller? No. The 120V controller is electrically incompatible with this 12V DC cable. Use a controller or switching system specifically rated for 12V DC. Can the heating cable be cut? Yes. It is designed to be trimmed to the required length, but the cut end must be fully sealed with the included waterproof end-seal kit before power is applied. Does a battery or power supply come with the cable? No. The customer must supply a compatible 12V DC power source, fuse, wiring, switch, and any required controller. Does the cable automatically turn itself off? No. Self-regulating technology adjusts the heat output, but the cable may continue drawing power until switched off or disconnected. How do I estimate battery runtime? Runtime depends on cable length, ambient temperature, battery capacity, wiring losses, and the actual self-regulating output. Calculate the complete electrical load before installation. Before Installation Confirm the pipe length, cable length, required current, battery capacity, fuse rating, wire gauge, polarity, insulation, and compatible 12V control method before connecting power. Refer to the complete manual for end-seal installation, electrical connection, insulation, testing, and maintenance requirements.
