STMOUTUO RV Water Pressure Regulator Valve — Lead-Free Brass, Pre-set 45 PSI with Adjustable 0–160 PSI Gauge

STMOUTUO RV Water Pressure Regulator Valve is a lead-free brass device that protects RV and trailer plumbing by reducing incoming water pressure and delivering an adjustable, stable flow.

If you connect your camper, trailer, or yard irrigation to municipal or campsite water, sudden high pressure can stress hoses, fittings, and appliances. The STMOUTUO regulator is built to lower and stabilize pressure, comes pre-set to 45 PSI, and includes an easy-to-read 0–160 PSI gauge so you can fine-tune output for different sources. Constructed from heat-cast, lead-free brass and tested to meet modern lead-content standards, it also ships with inlet cartridges and sealing tape for immediate, leak-free installation.

How does this regulator protect RV plumbing and fixtures?

The regulator reduces incoming pressure to safer levels so pipes, faucets, and onboard appliances experience less stress and wear. By preventing pressure spikes, it lowers the risk of leaks and premature failure in hoses and valves.

• Pre-set to 45 PSI to protect standard RV systems from high municipal pressure.
• Adjustable output for tailoring to delicate fixtures or heavy-duty needs.
• Solid brass body resists corrosion and mechanical damage over time.

Can I change the pressure to match different campgrounds or water sources?

Yes — the regulator is adjustable so you can modify output to match varying supply pressures. A clearly marked 0–160 PSI gauge lets you monitor inlet and outlet pressure while turning the adjusting handle to the desired setting.

• Factory pre-set at 45 PSI, ideal for most RV systems.
• Adjust with the built-in handle for higher or lower target pressures.
• 0–160 PSI gauge provides precise feedback during adjustment.

What materials and safety standards does the valve meet?

The STMOUTUO regulator uses lead-free brass made with heat-casting methods to ensure safe contact with drinking water. Each unit undergoes testing to confirm lead content is below strict regulatory limits for potable water systems.

• Constructed from lead-free brass for safe freshwater use.
• Tested to meet NSF/ANSI/CAN 372:2024 Section 3.1 lead-content requirements.
• Durable build designed for repeated campsite hookups and outdoor use.

What accessories come with the regulator and how easy is installation?

The package includes two inlet cartridges for basic filtration and a roll of sealing tape to prevent leaks at threaded connections. The regulator uses a standard 3/4-inch hose thread for direct compatibility with common American water spigots and RV supply hoses.

• Includes two replaceable inlet cartridges to reduce sediment ingress.
• Supply roll of plumber's tape for secure, leak-resistant joints.
• 3/4-inch hose thread for straightforward hookup—no special tools required for typical installations.

Who is this for? The STMOUTUO RV Water Pressure Regulator Valve suits RV owners, trailer renters, and anyone using municipal or campground water who wants to protect plumbing and appliances from damaging pressure. It also fits homeowners running temporary irrigation or fill lines where inlet pressure is unpredictable. If you need a durable, adjustable, lead-safe regulator with a clear gauge and handy installation accessories, this unit provides a practical, ready-to-install solution for safer water delivery.
