Built with a bronze body and a nitrile butadiene rubber (NBR) seal, this valve is rated for 200 psi working pressure (WOG) and fits 1-1\/2 inch pipe with female NPT connections on both ends. The Y-pattern configuration reduces turbulence and pressure drop compared to swing-type designs, making it well suited for systems where flow efficiency matters. Plumbers and pipefitters install this valve as part of new construction or retrofit projects in commercial and residential plumbing systems.\u003c\/p\u003e\n\u003cp\u003eThe NL7500C is used in water supply, general liquid service, and mechanical piping systems where backflow prevention is required. The FNPT x FNPT end connections allow straightforward inline installation with standard threaded pipe. It is appropriate for residential and light commercial applications and is commonly installed in boiler systems, pump discharge lines, and domestic water distribution piping where a compact, reliable check valve is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eY-pattern body reduces pressure drop and turbulence in the flow path\u003c\/li\u003e\n  \u003cli\u003eBronze body construction provides corrosion resistance in water and general liquid service\u003c\/li\u003e\n  \u003cli\u003eNitrile butadiene rubber (NBR) seal offers reliable shutoff against backflow\u003c\/li\u003e\n  \u003cli\u003e200 psi maximum working pressure (WOG) rating suits a wide range of plumbing applications\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for standard threaded pipe installation\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001:2008 quality management standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation check valve for 1-1\/2 inch threaded piping systems in residential and commercial plumbing and mechanical applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before beginning work. Use thread sealant tape or pipe joint compound rated for the service fluid on all threaded connections. Verify that the flow-direction arrow on the valve body is oriented correctly in the direction of intended flow before completing the installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Y-Pattern Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 200 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.985 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2008\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: NIBCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NL7500C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51539206275378,"sku":"NL7500C","price":386.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a07ec0e1997c37ac34dffa2dc55e204e.jpg?v=1785836564","url":"https:\/\/voomisupply.com\/products\/nibco-nl7500c-check-valve-1-1-2-in-y-pattern-fnpt-200-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
