The bronze body and nitrile butadiene rubber (NBR) seal provide corrosion resistance and reliable seating across a range of fluid service applications. Rated at 200 WOG (water, oil, gas), this valve is built for demanding service conditions. Female NPT connections on both ends allow for straightforward threaded installation. It is installed by licensed plumbers and pipefitters in residential and light commercial mechanical systems.\u003c\/p\u003e\n\u003cp\u003eThe NL75004 is suited for use in water supply, compressed air, and general fluid piping systems where backflow prevention is required. The Y-pattern body design offers lower pressure drop compared to swing-type check valves, making it a practical choice in systems where flow efficiency matters. At 1\/4 inch pipe size, this valve fits smaller branch lines and instrument connections commonly found in HVAC, plumbing, and light industrial piping layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eY-pattern body design provides lower pressure drop than swing-style check valves\u003c\/li\u003e\n  \u003cli\u003eRated 200 WOG for use in water, oil, and gas service\u003c\/li\u003e\n  \u003cli\u003eBronze body offers corrosion resistance in wet and general-service environments\u003c\/li\u003e\n  \u003cli\u003eNitrile butadiene rubber (NBR) seal delivers reliable shut-off and chemical compatibility\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for standard threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch pipe size for small-diameter branch and instrument piping\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\/4 inch FNPT threaded piping systems in plumbing, HVAC, and light industrial applications rated up to 200 WOG.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system completely before removing any existing valve or fitting. Apply thread sealant or PTFE tape to male threads per manufacturer and applicable IPC guidelines before assembly. Do not over-torque threaded connections on bronze-body valves, as this can crack fittings or distort seats.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 200 WOG\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\u003eWeight\u003c\/strong\u003e: 0.507 pounds\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: NL75004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51539702579506,"sku":"NL75004","price":146.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35c32ddf39afec57d5db6672463a61a2.jpg?v=1785844034","url":"https:\/\/voomisupply.com\/products\/nibco-nl75004-y-pattern-check-valve-1-4-in-fnpt-200-wog","provider":"Voomi Supply","version":"1.0","type":"link"}
