STMOUTUO RV Water Pressure Regulator Valve 3/4-inch Hose Thread — Lead-Free Brass, Adjustable 0–160 PSI Gauge

STMOUTUO RV Water Pressure Regulator Valve is a lead-free brass, adjustable regulator engineered to protect RV and household plumbing by reducing high inlet pressure to a safe, user-set level.

High or fluctuating municipal water pressure can damage hoses, faucets and appliances in an RV, trailer, or home supply line. This STMOUTUO regulator arrives preset to 45 PSI for immediate protection, and includes tools and accessories so you can fine-tune the output pressure, filter incoming water, and create secure connections. Its 3/4-inch hose thread matches standard U.S. fill connections, and the lead-free brass construction meets NSF lead-free requirements for safer potable water use.

How does this regulator protect my RV plumbing?

The regulator reduces spikes and sustained high pressure that stress pipes, fittings, and fixtures. By lowering inlet pressure to a controlled output, it prevents leaks and premature wear while improving the reliability of onboard systems.

• Reduces incoming pressure to a preset 45 PSI (adjustable)
• Lead-free brass body resists corrosion and contamination
• Prevents overpressurization of hoses, faucets and appliances

Can I adjust the pressure and monitor it accurately?

Yes — the unit ships preset at 45 PSI but includes a built-in adjustment mechanism and a wide-range gauge (0–160 PSI) so you can set the outlet pressure to match your equipment's needs. The included 2-in-1 screwdriver makes field adjustments quick and tool-free.

• Factory preset to 45 PSI for instant protection
• Adjustable pressure with included 2-in-1 screwdriver
• 0–160 PSI gauge for clear, measurable readings

What accessories come with the regulator and why do they matter?

The kit contains installation and filtration accessories to ensure a leak-free, debris-reduced connection right out of the box. Those extras simplify setup at campgrounds or home and add small protections that reduce maintenance over time.

• Two inlet filters to block sand and particulate matter
• Raw (plumber's) tape to seal threaded connections
• Removable-head 2-in-1 screwdriver for installation and pressure adjustment

Is the STMOUTUO regulator compatible with my water hookup?

The regulator uses a standard 3/4-inch hose thread commonly found at RV parks, garden faucets and many municipal connections in the U.S., so it installs quickly without adapters in most situations. Its robust threaded connection also helps maintain a tight seal under pressure.

• Standard 3/4-inch hose thread for U.S. water sources
• Durable threads and brass construction reduce cross-threading and leaks
• Compact form factor fits tight inlet spaces on RVs and trailers
