CamcoPre-Set 40-50 PSICSA Low-Lead CertifiedCamco 40064 RV Brass Water Pressure Regulator with Gauge

Campground water pressure can spike well above 100 PSI -- far beyond what RV plumbing, fittings, and fresh-water hoses are designed to handle. The Camco 40064 screws onto any standard 3/4" garden hose thread pedestal connection and automatically reduces incoming pressure to a safe 40-50 PSI, giving you steady, high-flow water delivery without risking a burst hose or blown fitting inside your rig.

Built Tougher Than Plastic -- Because Campground Pressure Is No Joke

Many budget regulators use plastic housings that crack under UV exposure or cyclic pressure stress. The Camco 40064 uses a solid brass body that resists corrosion, handles years of outdoor use, and maintains a consistent seal through thousands of connect-disconnect cycles. The integrated dial gauge reads in both PSI and kPa, so you can see exactly what the pedestal is pushing before it ever reaches your rig.

The regulator is factory pre-set -- no adjustment needed. Just thread it on female-to-male (inlet female GHT, outlet male GHT) and you are protected. Camco's high-flow internal valve geometry delivers approximately 15-20% more water flow than older-style low-flow regulators, so you get real shower pressure at 40-50 PSI instead of a trickle.

Solid Brass Body

Corrosion-resistant brass construction outlasts plastic regulators in UV-exposed outdoor environments. Rated for years of seasonal campground use.

Dual-Scale Gauge

Easy-read dial displays both PSI and kPa. Color-coded zones: yellow under 40 PSI, green 40-50 PSI, red above 50 PSI.

High-Flow Design

Internal valve geometry allows 15-20% more water flow than standard regulators -- no sacrificing shower pressure for protection.

Universal GHT Threads

Standard 3/4" garden hose threads fit virtually every campground water pedestal and RV fresh-water inlet without adapters.

Reading the Gauge at the Hookup

Before connecting to your RV's fresh-water inlet, thread the regulator onto the campground pedestal, then attach your drinking-water hose to the outlet. Turn the water on slowly and watch the gauge. A reading in the green zone (40-50 PSI) confirms the regulator is seated and working. A red-zone reading at the pedestal before you even turn on flow is a sign the incoming supply is extremely high -- the regulator will control it, but it is worth noting for your records. A yellow-zone reading simply means that particular site is running low municipal pressure; nothing is wrong with your regulator.

High-Flow Advantage: The 40064's internal orifice is sized for full-flow performance. Unlike restrictor-type regulators, you won't sacrifice water volume at 40-50 PSI -- showers, filling the tank, and running multiple fixtures all perform normally.

Installation in 60 Seconds

  • Thread the female inlet end of the regulator onto the campground water pedestal (hand-tight plus a quarter turn -- do not over-torque brass threads).
  • Connect your drinking-water hose to the male outlet end of the regulator.
  • Run the other end of your hose to your RV's city water inlet.
  • Turn the pedestal valve on slowly and confirm the gauge reads green.
  • No tools required for normal installation.
Thread Tip: Use a short section of NSF-rated Teflon tape on the male threads if you notice any weeping at the connection. Do not use pipe dope -- garden hose thread fittings are designed for tape or washer sealing, not compound.

Outdoor Use -- Important Limitation

The Camco 40064 is rated and warranted for outdoor use only. Do not install it inside a wet bay, pass-through, or enclosed compartment where it cannot breathe. The gauge face is not waterproof-rated for submersion; protect it from direct rain spray when possible and drain the regulator before freezing temperatures arrive to prevent cracking the brass body or gauge internals.

Winterization: Disconnect and drain this regulator before temperatures drop below 32 deg F. Water trapped inside the brass body or gauge mechanism can freeze and crack the housing, voiding the warranty.

Who Uses This Regulator

  • Full-timers connecting at a new campground every few days where pedestal pressure is unknown and unpredictable.
  • Weekend warriors who want one reliable, set-and-forget solution instead of worrying about plumbing damage.
  • Boondockers filling tanks at spigots where municipal supply pressure can be very high.
  • RV technicians who recommend a brass-body unit to customers upgrading from failed plastic regulators.
Maintenance Tip: Inspect the inlet screen filter (if present in your hose fitting) each season. Flush the regulator body by running water through it briefly before first hookup each year. Check the gauge face for fogging or cracking -- a fogged gauge may indicate internal moisture and should be replaced before trusting the reading.

Important Information
  • Rated for outdoor use only -- do not install in enclosed compartments.
  • Drain and store before freezing temperatures (below 32 deg F) to prevent cracking the brass body and gauge mechanism.
  • Hand-tighten only -- do not use a pipe wrench on garden hose threads; over-torquing can damage the brass fittings or crack the gauge housing.
  • This regulator is factory pre-set and non-adjustable -- output pressure will always be in the 40-50 PSI range; it cannot be re-set in the field.
  • Not rated for use with hot water or steam -- for cold fresh-water supply lines only.
  • If the gauge reads in the red zone even after the regulator is fully engaged, the regulator is functioning correctly and holding pressure down; the red indicates what the upstream supply would have been without protection.
  • Replace immediately if the gauge face is cracked, fogged, or unreadable -- a damaged gauge may not accurately reflect internal pressure.
