[New Upgrade Process]: The inside of the pressure gauge is filled with high class silicone oil. The clarity, stability and seismic performance are higher than other gauge and it is not easy to fade. The gauge is filled with oil to prevent water intrusion and rust, and the sealing is stronger, the service life is prolonged. [Lead Free Brass]: Water Pressure Regulator is tested strictly to meet NSF lead-free requirements of less than 0.25%, silver body, is different from other regulators, class C46500 LEAD-FREE BRASS treated by hot casting and plating double process technology, effectively inhibit bacterial growth, make the lead content of the RV regulator reach the minimum standard set by the market industry, which make it more safer and healthier [Dual-Layer Inlet Screened Filter]: Water Pressure Regulator is designed with 3/4 NH thread (hose thread or garden hose thread), compatible with All US water sources. The Dual-Layer inlet screened filter helps to filter particles like gravel, debris to prevent impurity blocking and valve body damage, bring you continuous water flow which is about 2-4 gallons per minute, and will not reduced the water flow rate. [Adjustable Water Pressure Regulator]: Water Pressure Regulator adjust Water Pressure from 0-160PSI, different campsites have different water pressures and are suitable for different harsh environments. Adjust screw on the top of regulator to select your desire pressure setting. Turn clockwise to increase pressure, turn counterclockwise to decrease pressure. This regulator is preset at 45 PSI. [Removable Valve Spool]: Water Pressure Regulator has compact size for easy to use, the removable valve spool for easily cleaning or replacement when needed by removing it. Pay attention to protect the sealing of the product when removing it!
