The valve features female NPT connections on both ends and a bronze body rated for 200 psi working pressure, making it suitable for water, oil, and gas service within that pressure range. A nitrile butadiene rubber (NBR) seal provides reliable shutoff and resistance to a range of common fluids. This valve is installed by licensed plumbers and pipefitters in commercial and residential piping applications where backflow prevention is required.\u003c\/p\u003e\u003cp\u003eThe NL75008 is suited for 3\/4 inch threaded piping systems in residential and light commercial installations. The Y-pattern body design orients the seat at an angle to the flow path, reducing pressure drop compared to straight-pattern check valves. It is commonly installed in water supply lines, HVAC hydronic systems, and general-purpose plumbing where a threaded, in-line backflow preventer is needed. Both FNPT end connections allow direct threaded makeup to standard NPT pipe and fittings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eY-pattern body reduces flow restriction and pressure drop compared to straight-body designs\u003c\/li\u003e\n\u003cli\u003eBronze body construction provides corrosion resistance for water and fluid service\u003c\/li\u003e\n\u003cli\u003eNitrile butadiene rubber (NBR) seal material suits common water and petroleum-based fluids\u003c\/li\u003e\n\u003cli\u003e200 psi maximum working pressure rating\u003c\/li\u003e\n\u003cli\u003eFemale NPT x Female NPT connections for straightforward threaded installation\u003c\/li\u003e\n\u003cli\u003eManufactured under ISO 9001:2008 quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation check valve for 3\/4 inch female NPT threaded piping systems in residential and commercial plumbing and hydronic applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before removing or installing any threaded valve. Apply thread sealant or PTFE tape to male NPT threads before makeup, and tighten to a firm, leak-free seating without over-torquing bronze fittings. Verify flow direction arrow on the valve body is oriented correctly with system flow before returning the line to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Y-Pattern Check Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 200 psi\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\u003eWeight\u003c\/strong\u003e: 0.885 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2008\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: NL75008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51541616230706,"sku":"NL75008","price":117.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9ec09dc5480c39d73f5f4dfb30cad6c.jpg?v=1785880618","url":"https:\/\/voomisupply.com\/products\/nibco-nl75008-check-valve-3-4-inch-y-pattern-fnpt-bronze","provider":"Voomi Supply","version":"1.0","type":"link"}
