It accepts a female NPT (FNPT) connection and is rated for Class 125 service at 125 psi. The locknut is constructed from lead-free brass, making it suitable for potable water applications where lead-free compliance is required. Plumbers and pipefitters use this type of hardware when mounting threaded pipe connections through enclosures, tanks, or wall panels. Its compact profile and standard NPT threading make it a straightforward fit into most commercial and residential plumbing assemblies.\u003c\/p\u003e\u003cp\u003eThis locknut is used in residential and light commercial plumbing systems where a threaded pipe or fitting must be anchored through a surface. Typical applications include tank fittings, water heater connections, and any installation where a pipe thread passes through a panel and requires a locking counterpart on the back side. The FNPT end connection accepts standard tapered pipe threads. Its lead-free construction meets regulatory requirements for systems carrying drinking water.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free brass construction meets potable water compliance requirements\u003c\/li\u003e\n\u003cli\u003e3\/4-inch FNPT connection accepts standard NPT tapered pipe threads\u003c\/li\u003e\n\u003cli\u003eClass 125 pressure rating at 125 psi for light to moderate service\u003c\/li\u003e\n\u003cli\u003eCompact locknut profile suitable for panel and bulkhead mounting\u003c\/li\u003e\n\u003cli\u003eSold individually — no minimum order beyond single-unit quantity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for 3\/4-inch NPT threaded pipe systems operating within Class 125 pressure limits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters. Shut off system pressure and drain the line before removing or installing any threaded pipe hardware. Use appropriate pipe thread sealant or PTFE tape on NPT threads per IPC guidelines. Do not overtighten — snug plus hand-wrench turns is sufficient for brass fittings to avoid cracking.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Locknut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT BRASS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: XNL119-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51538309579058,"sku":"XNL119-12","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4b5809d0dc4914894c1c3cdf5d792f1_cce80d95-18bf-4008-83c0-b78bf4764488.jpg?v=1785822618","url":"https:\/\/voomisupply.com\/products\/merit-brass-xnl119-12-brass-pipe-locknut-3-4-in-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
