40052 is a Camco fresh water pressure regulator designed to protect RV plumbing and water hoses from excessive campground water pressure. Its brass construction reduces incoming water pressure to a preset range of 40–50 PSI, helping prevent hose failure and damage to internal water lines. It features 3/4-inch garden hose connections and does not include a pressure gauge. A practical accessory for connecting your RV to an external water supply.
