It features a bronze body. Rated to 175 psi and 33°F to 180°F. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThe Wilkins 975XL3N Reduced Pressure Principle Backflow Assembly is purpose-built for irrigation and landscape applications where space constraints and replacement efficiency are critical. Designed in an N-pattern configuration, the 975XL3N features a lay length optimized for direct drop-in replacement of existing irrigation backflow installations, eliminating the need for additional fittings or enclosure modifications. Built on the proven 975XL3 platform, it provides high hazard protection against backsiphonage and backpressure while reducing installation time, labor costs, and long-term maintenance through Wilkins’ EZSwap® modular check design and shared repair components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eN-pattern configuration with lay length designed for drop-in replacement of legacy irrigation and landscape backflow installations, reducing labor, materials, and enclosure rework.\u003c\/li\u003e\n\u003cli\u003eAll-bronze body ensures durability against the elements, with a Noryl®* check body and stainless-steel fasteners to resist corrosion over time.\u003c\/li\u003e\n\u003cli\u003eShares body, EZSWAP® modular checks, relief valve components, and repair kits with the 975XL3 platform for simple maintenance and stocking and service efficiency.\u003c\/li\u003e\n\u003cli\u003eTest ports located on valve’s centerline make install and testing easy\u003c\/li\u003e\n\u003cli\u003eInterlocking connected checks allow for ¼-turn access for fast disassembly and maintenance\u003c\/li\u003e\n\u003cli\u003eLow-cost repair kits extend the lifespan at a significantly lower cost\u003c\/li\u003e\n\u003cli\u003eLead Free* bronze body (0.25% max. weighted average lead content) suitable for potable and irrigation applications.\u003c\/li\u003e\n\u003cli\u003eASSE Listed, UPC® Listed, Meets NSF\/ANSI\/CAN 61 \u0026amp; 372 requirements; Approved by the Foundation for Cross-Connection Control and Hydraulic Research at the University of Southern California; Safe Drinking Water Act Compliant\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.
