Why You Need This

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

Compared to alternatives in the rv accessories category, the Camco 40055 RV Water Pressure Regulator, Brass excels with holds hookup pressure to a safe 40-50 psi to protect rv plumbing and hose fittings and solid brass body resists cracking and weather far better than plastic regulators. However, keep in mind fixed pressure setting, so no adjustment for rigs that want a different psi and a separate inline filter is still needed if you want filtration in addition to regulation — consider whether these factors align with your specific needs before purchasing.
