It uses female NPT connections on both ends and is rated for up to 300 psi working pressure, making it suitable for water, oil, and gas service within its rated limits. The bronze body and bronze seat offer corrosion resistance in common plumbing service conditions. A Y-pattern configuration reduces turbulence and pressure drop compared to a standard swing check, which is an advantage in systems where flow efficiency matters. Licensed plumbers and pipefitters are the primary installers of this valve type.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for residential and light commercial plumbing systems, hydronic heating lines, and industrial fluid-transfer applications where backflow prevention is required. The 3\/8 inch FNPT x FNPT end connections make it compatible with threaded pipe runs in tight spaces where a compact inline check is needed. Its 300 WOG rating covers a broad range of common service media. Maximum rated temperature is 366 degrees F, which accommodates most hot-water and steam-adjacent applications within that threshold.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eY-pattern design reduces pressure drop and turbulence compared to standard swing check valves\u003c\/li\u003e\n  \u003cli\u003e300 psi maximum working pressure rated for water, oil, and gas service\u003c\/li\u003e\n  \u003cli\u003eBronze body and bronze seal material for corrosion resistance in plumbing service\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch FNPT x FNPT end connections for threaded pipe installation\u003c\/li\u003e\n  \u003cli\u003eMaximum service temperature of 366 degrees F\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 threaded check valve for 3\/8 inch pipe systems using NPT fittings in plumbing, hydronic, and light industrial fluid-handling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\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 depressurize the line before threading the valve into place. Apply appropriate thread sealant or PTFE tape to the male threads of the mating pipe before connection. Verify flow direction arrow on the valve body aligns with the intended direction of flow before final tightening.\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: 3\/8 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\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: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.534 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: NL7J005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51538247811378,"sku":"NL7J005","price":110.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67d92b04c0208c60efcc598c01a7c10c.jpg?v=1785820740","url":"https:\/\/voomisupply.com\/products\/nibco-nl7j005-bronze-check-valve-3-8-in-fnpt-300-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
