Camco40-50 PSILead-Free BrassCamco 40052 RV Water Pressure Regulator -- Inline Protection for Campground Hookups

Campground water supplies can spike well above 100 PSI -- far beyond the 40-60 PSI safe range most RV plumbing systems are designed to handle. The Camco 40052 inline pressure regulator steps that pressure down to a consistent 40-50 PSI every time you connect, protecting your fresh-water hose, pump, fittings, and interior lines from over-pressure damage without any adjustment needed.

Screw It On, Hook Up, and Stop Worrying About Water Pressure

This is one of those components that should be on every RV before it ever pulls into a campground. The Camco 40052 is a fixed, non-adjustable inline regulator -- meaning there are no knobs, no gauges, and no setup. Thread it onto the spigot before your fresh-water hose and it automatically holds output pressure in the 40-50 PSI range regardless of what the park is pushing through the line.

Built entirely from lead-free brass, the 40052 complies with federal lead-content regulations (NSF/ANSI 61 material standards for potable water contact). The solid brass body resists corrosion, UV exposure, and the physical abuse of being connected and disconnected at dozens of sites over a season.

Fixed 40-50 PSI Output

No adjustment required. Automatically limits output to a safe range for RV plumbing, hoses, and pump fittings.

Lead-Free Brass Body

Solid brass construction meets federal lead-free standards for potable water contact. Durable through repeated connection cycles.

Standard 3/4 in. Hose Threads

Female inlet and male outlet both use 3/4 in. GHT (garden hose thread) -- compatible with standard campground spigots and RV fresh-water hoses.

No Tools, No Setup

Hand-tighten directly onto the campground spigot. Compact size fits easily in a utility drawer or hookup kit bag.

Why RV Plumbing Needs Pressure Protection

Most RV manufacturers spec their fresh-water systems for a maximum of 60 PSI, and many recommend staying at or below 50 PSI for long-term hose and fitting life. Municipal water supplies and campground systems commonly deliver 80-100+ PSI. Even a single high-pressure hookup can crack fittings, burst hose connections, damage the city water inlet, or stress the check valve on your onboard pump.

Good Practice at Every Site: Thread the Camco 40052 directly onto the campground spigot first, then connect your drinking-water safe hose to the regulator's male outlet. This puts the regulator at the source so the entire hose run is protected, not just the connection at the coach.

Compatibility and Fitment

The 40052 uses standard 3/4 in. GHT (garden hose thread) on both ends -- female on the inlet (attaches to spigot) and male on the outlet (attaches to your fresh-water hose). This is the universal thread standard used on virtually all North American campground water pedestals and RV fresh-water inlets.

  • Compatible with Class A, Class B, Class C motorhomes, fifth wheels, travel trailers, and toy haulers
  • Works with any standard 5/8 in. or 3/4 in. ID drinking-water hose using GHT fittings
  • No adapter needed for most campground connections in the US and Canada
  • Can also be used on boat marina hookups that supply city water to the vessel
Fixed vs. Adjustable: The 40052 is a fixed regulator -- output is preset at the factory to 40-50 PSI. If your rig needs a specific pressure dialed in (for example, a system with a low-pressure tankless water heater), consider an adjustable regulator with a gauge. For the vast majority of RV fresh-water systems, 40-50 PSI is the correct working range.

Installation Tips

  • Hand-tighten only -- no pipe wrench needed for a leak-free seal when used with a washer in your hose end
  • Check or replace the rubber washer inside your hose fitting each season; a worn washer causes drips at the connection, not a regulator failure
  • Do not use Teflon tape on GHT (garden hose thread) connections -- GHT seals via a rubber washer, not thread engagement
  • Store the regulator in your hookup bag between uses to prevent the internal spring and seat from sitting under pressure when not connected
Maintenance Note: Inspect the brass body and inlet screen annually. Sediment from campground water supplies can collect in the inlet and reduce flow. A quick rinse and brush clears most buildup. Replace the unit if the body shows cracking, heavy mineral deposits inside the bore, or output pressure climbs above 55 PSI under load (tested with an inline gauge).

Important Information
  • This is a FIXED regulator -- output pressure is preset at 40-50 PSI and cannot be adjusted in the field.
  • Always confirm a rubber washer is present in your hose coupling before connecting. Missing washers cause leaks at the threads, not inside the regulator.
  • Do not over-tighten. GHT connections seal on a washer face -- excessive torque can crack the brass hex or strip the female threads on an aluminum spigot.
  • Not designed for use with hot water -- install on the cold fresh-water inlet only.
  • If campground inlet pressure exceeds the regulator's rated maximum inlet (approximately 125 PSI), regulator performance may be reduced or the body may be damaged. Extremely high-pressure industrial or agricultural sources are not suitable hookup points.
  • Hose, pressure gauge, and additional fittings are NOT included.
  • 90-day limited warranty covers manufacturer defects only -- physical damage from over-tightening or freezing is not covered.
