It is rated to 175 psi and up to 180°F. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThe 375ST Reduced Pressure Principle Backflow Preventer offers high hazard protection against both backsiphonage and backpressure of contaminated water into the potable water supply. Materials include engineered plastic construction and quality 300 series stainless steel fasteners, springs, ball valves, and struts. The 375ST is utilized in systems where liquids are corrosive to copper alloys like bronze valves, including medical diagnostic equipment applications, food processing, distilleries, and breweries. It comes standard with full port QT ball valves, and features a maximum working water pressure of 175 psi, maximum working water temperature of 180°F, and hydrostatic test pressure of 350 psi.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAll stainless steel and engineered plastic construction resists corrosion\u003c\/li\u003e\n\u003cli\u003eRepair Kits provide cost savings by avoiding full Backflow Preventer replacement\u003c\/li\u003e\n\u003cli\u003eApplicable for systems that are corrosive to bronze valves\u003c\/li\u003e\n\u003cli\u003eExcellent for food service use\u003c\/li\u003e\n\u003cli\u003eLow-lead law compliant\u003c\/li\u003e\n\u003cli\u003eASSE® Listed 1013\u003c\/li\u003e\n\u003cli\u003eApproved by the Foundation for Cross Connection Control and Hydraulic Research at the University of Southern California\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat hazard level is this RPZ approved for?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt is rated for high health hazard (toxic) cross-connections, so it may be used on either high or low hazard service.
