Cold Weather Water Hose. Keep your water supply flowing even in freezing temperatures. Camco's Heated Water Hose combines a drinking-water safe hose with a self-regulation heat source which is encapsulated in an all-weather, PVC coating for durability. Features machined and nickel-plated fittings for maximum corrosion protection. Includes a female-to-male adapter for connection of the water source to either end of the hose; depending on the location of your electrical connection. This is a 12' hose.
