The core of the Camco Heated Drinking Water Hose is made with an NSF 61 certified, drinking water safe hose that is BPA, phthalate and lead free. The Heated Drinking Water Hose won't leach harmful chemicals into your water or leave it tasting like plastic the way standard garden hoses do. It is ideal for RVs, livestock, agriculture, kennels and other industrial, commercial and residential uses. The fittings are heavy duty machined and plated for maximum corrosion resistance and the durable exterior jacket protects water hose and electrical components from damage or exposure.
