It features a 1\/4 inch pipe size with female NPT (FNPT) connections on both ends, a bronze body, and a polytetrafluoroethylene (PTFE) seat seal. Rated at 300 WOG (water, oil, gas), it handles demanding service conditions up to 300 psi. This valve is installed by licensed plumbers and pipefitters in both commercial and industrial applications where reliable backflow prevention is required.\u003c\/p\u003e\n\u003cp\u003eThe NL7K004 is suited for use in water, oil, and gas piping systems where a compact, inline check valve is needed. The Y-pattern body design offers lower pressure drop compared to swing-type check valves and is appropriate for horizontal or vertical installations. Its bronze construction and PTFE sealing make it compatible with a range of fluid media including water and light oils. Typical installation scenarios include supply lines, equipment protection, and process piping in light industrial and commercial facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eY-pattern body for reduced pressure drop and smooth flow characteristics\u003c\/li\u003e\n  \u003cli\u003e300 WOG pressure rating, suitable for water, oil, and gas service up to 300 psi\u003c\/li\u003e\n  \u003cli\u003eBronze body construction for corrosion resistance in plumbing and industrial environments\u003c\/li\u003e\n  \u003cli\u003ePTFE seat seal provides reliable, low-friction seating across a wide temperature range\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for straightforward threaded installation\u003c\/li\u003e\n  \u003cli\u003eRated to 366 degrees F maximum operating temperature\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 water, oil, and gas service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements where gas service is involved. Shut off and depressurize the system completely before removing or installing the valve. Use thread sealant or PTFE tape on all male NPT threads per standard practice. Verify that flow direction matches the arrow or markings on the valve body before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 366 degrees F (185 degrees C)\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: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.539 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: NL7K004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51543463690546,"sku":"NL7K004","price":116.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67d92b04c0208c60efcc598c01a7c10c_aa1242bd-9269-410d-a041-11b1a0cbdb71.jpg?v=1785918995","url":"https:\/\/voomisupply.com\/products\/nibco-nl7k004-y-pattern-check-valve-1-4-inch-fnpt-300-wog","provider":"Voomi Supply","version":"1.0","type":"link"}
