Camco 40055 RV Water Pressure Regulator, Brass
A solid-brass regulator that threads between the campground spigot and your RV hose, holding city water pressure to a safe 40-50 PSI. The lead-free brass body holds up to sun, weather, and repeated hookups far better than plastic regulators.

You screw the hose onto a park spigot and the water hammer slams your plumbing at 80+ psi — the pressure that bulges hoses, splits fittings, and turns a $16 connection mistake into a flooded underbelly. The brass 40055 is factory-preset to 40–50 psi, so every hookup is protected whether it is a full-hookup resort or a dirt-road ranger station.
🏆 How It Compares
A solid-brass regulator that locks campground pressure to a safe 40–50 PSI before it reaches your RV plumbing — the lead-free metal body shrugs off sun and weather far longer than plastic regulators, and standard 3/4-inch garden-thread fittings make it a 30-second install between spigot and hose. The pressure setting is fixed, so there is no dialing up or down for rigs that want a different PSI, and it only regulates — pair it with an inline filter if your park water also needs treating.
Pros & Cons
