OULEME RV Water Pressure Regulator Valve, Lead-Free Brass — Adjustable 3/4" Gauge & Inlet Filter

The OULEME RV Water Pressure Regulator Valve is an adjustable, lead-free brass pressure reducer with a silicone-filled gauge and inlet filter designed to protect RV plumbing from high city water pressure.

Whether you're hooked up at a campground or filling your freshwater tank, this reducer keeps incoming pressure within safe limits to prevent damaged hoses, fittings, and fixtures. Constructed from lead-free brass and factory-set to roughly 45 PSI, the unit accepts standard 3/4" fittings and can handle system pressures up to 160 PSI. The included silicone-oil gauge gives steadier readings while the built-in inlet filter blocks debris, making installation and use straightforward.

How does this regulator protect my RV plumbing?

The valve lowers and stabilizes city water pressure so fragile components—like seals, water heaters, and camper faucets—aren't exposed to spikes. Reducing excessive pressure extends the life of hoses and prevents sudden leaks.

• Reduces incoming pressure from high municipal sources to safer levels
• Factory preset to ~45 PSI, adjustable by hand for custom settings
• Accepts 3/4" standard hose fittings for easy hookup
• Lead-free brass construction minimizes corrosion and health concerns

How do I install and adjust the OULEME pressure reducer?

Installation is simple and requires no special tools: thread the regulator between your shore power water source and RV inlet using standard 3/4" connections. Adjust pressure by turning the top handle; the silicon-filled gauge provides a clear, steady reading while you fine-tune.

• Thread onto 3/4" hose or pipe—no adapters usually required
• Hand-turn handle for pressure changes; no tools necessary
• Silicone oil gauge reduces needle wobble for accurate adjustment
• Built-in inlet filter captures sediment before it enters plumbing

What materials and certifications ensure safe water use?

The regulator is machined from lead-free brass and meets NSF 61/372 and CSA standards for potable water systems, keeping lead content under strict limits. These certifications support safe contact with drinking water in RV systems.

• Lead content below 0.13% for safer water contact
• NSF 61/372 and CSA compliance for potable water applications
• Durable brass body resists wear and outdoor exposure
• Silicone-filled gauge extends gauge life and accuracy
