The core of the Camco Taste PURE 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. Providing water line freeze protection down to -20degF (-28degC), the energy-saving thermostat only heats as needed, saving you money on your electric bill. The internal diameter of the hose is 5/8-inch, and the fittings are heavy-duty machined and plated for maximum corrosion resistance. The durable exterior jacket protects the water hose and electrical components from damage or exposure. Operates on 120VAC and uses an 18AWG 6-foot power cord with LED indicator. CSA Low Lead Content Certified to NSF/ANSI 372 and compliant with all federal and state level Low Lead Laws. | CAMCO Heated Drinking Water Hose in Blue | Size 25'
