The AquaFresh High Pressure Drinking Water Hose from Valterra is a necessity for your RV! The drinking hose is engineered for high pressure RV hookups with Hi-Flow fittings and a 120 psi working pressure. With an included hose gripper, installation is easy! The metal hose savers are pre-installed to prevent kinks when attached to the spigot. Each hose is constructed entirely of NSF-listed materials for drinking water safety.
