Built with a reinforced nylon body, this unit is suited for plumbing and irrigation systems where a compact, corrosion-resistant assembly is required. The 3\/4 inch FNPT connections and quarter-turn ball valve design allow for straightforward installation and isolation without specialized tooling. Licensed plumbers and pipefitters install this type of device on commercial and residential service lines in compliance with local cross-connection control requirements.\u003c\/p\u003e\n\u003cp\u003eThe 34-375XLB is applied on 3\/4 inch service lines in residential, light commercial, and irrigation applications where a reduced pressure zone assembly is required by code. Typical installations include domestic water service entry points, lawn irrigation systems, and equipment protection on boiler makeup water lines. The FNPT end connections are compatible with standard threaded pipe fittings in these configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduced pressure zone design provides the highest level of backflow protection for potable water systems\u003c\/li\u003e\n  \u003cli\u003eReinforced nylon composite body resists corrosion in damp or wet installation environments\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch FNPT end connections for standard threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003eQuarter-turn ball valve shutoffs allow fast isolation during service or testing\u003c\/li\u003e\n  \u003cli\u003eComposite vessel construction reduces overall assembly weight compared to brass alternatives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style reduced pressure backflow preventer for 3\/4 inch threaded plumbing and irrigation service lines requiring cross-connection control protection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber or certified backflow prevention assembler in accordance with local plumbing codes and authority having jurisdiction requirements. Shut off the water supply and relieve line pressure before beginning installation. The assembly should be mounted in a horizontal orientation unless the manufacturer documentation specifies otherwise, and adequate clearance must be provided for annual testing and relief valve discharge. After installation, the device must be tested and documented by a certified tester per local cross-connection control program requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection Style\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Reinforced Nylon (Composite)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Quarter-Turn Ball Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssembly Type\u003c\/strong\u003e: Reduced Pressure Zone Backflow Preventer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 375XL\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILKINS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 34-375XLB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILKINS","offers":[{"title":"Default Title","offer_id":51523401646386,"sku":"375XLB-34","price":1009.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/249af63206a369370d25f370a8aaf08d.jpg?v=1785441862","url":"https:\/\/voomisupply.com\/products\/wilkins-34-375xlb-reduced-pressure-backflow-preventer-3-4","provider":"Voomi Supply","version":"1.0","type":"link"}
