Camco Brass RV Water Pressure Regulator with Gauge 40–50 PSI Preset — Lead-Free, 3/4" Thread

City water hookups can deliver pressures far higher than recreational plumbing is built to handle. The Camco 40064 brass pressure regulator with an easy-read, color-coded gauge helps prevent damage by lowering and stabilizing incoming water pressure before it reaches faucets, appliances, or hose lines. Built from lead-free brass and preset to a safe PSI range, it’s a simple inline device that installs directly onto standard 3/4" garden hose threads.

How does this regulator protect my RV plumbing?

The regulator automatically reduces high inlet pressure to a safer outlet level, reducing stress on faucets, pumps, flexible hoses, and fixtures. By preventing pressure spikes, it lowers the chance of leaks and burst lines during campground hookups.

• Preset 40–50 PSI safe operating range to limit harmful pressure.
• Color-coded gauge shows pressure at a glance so you can confirm proper operation.
• Durable lead-free brass construction resists corrosion for long service life.
• Max incoming pressure rated to 125 PSI for clear limits and protection.

Is the Camco regulator safe for drinking water and compliant with regulations?

Yes: the regulator is made of lead-free brass and meets NSF/ANSI 372 standards for lead content, ensuring it’s safe for potable water lines in RV and marine applications. That compliance helps you meet federal and state lead-free requirements for drinking water delivery.

• CSA lead-free content certified to NSF/ANSI 372.
• Suitable for potable water connections at campsites and marinas.
• Brass body avoids plastic taste and withstands outdoor environments.

How easy is installation and use at a campground hookup?

Installation is straightforward: screw the regulator onto standard 3/4" garden hose threads and attach your hose. The gauge is color-coded, so you can quickly confirm the downstream pressure without special tools or adjustment.

• Fits standard 3/4" garden hose connections for quick setup.
• Pre-set regulator requires no field calibration.
• Simple visual gauge for instant pressure verification.
• Designed for outdoor use — keep it protected from freezing conditions.

What features should I expect for durability and performance?

Camco’s regulator uses high-quality brass and patented design elements to deliver consistent pressure reduction under normal campsite conditions. The built-in PSI guard and the tested construction provide predictable performance over many seasons of use.

• Patented design and factory testing for reliable operation.
• Brass body minimizes wear and resists corrosion from outdoor exposure.
• Compact form factor that fits in typical RV utility storage.
• Clear gauge allows ongoing monitoring without removing the regulator.

Who is this for? The Camco Brass RV Water Pressure Regulator with Gauge is for RV owners, boaters, and anyone using city or marina water hookups who wants a low-effort way to protect plumbing and extend the life of hoses, fixtures, and onboard appliances. It’s ideal for campers who frequently stay at public hookups, seasonal RVers who need reliable, code-compliant potable water components, and those who prefer simple, durable hardware that requires no adjustments. Remember to drain or remove the regulator before freezing temperatures to avoid damage.
