The Vevor pipe heating cable is designed to help protect water pipes from freezing in cold weather. This 3' heat tape delivers 7W per foot constant power and uses a built-in thermostat for automatic operation. It is suitable for PVC hose, PEX, metal, and plastic pipes in applications such as RVs, basements, garages, gardens, water tanks, and outdoor hydrants. The durable construction includes fiberglass, PVC insulation, copper wire shielding, and an IP68 waterproof rating. Its pre-assembled design allows for straightforward installation when laid straight along the pipe.
