It provides a tight, vibration-resistant connection on FNPT (female national pipe taper) threaded pipe ends. Rated at 125 psi at Class 125, this locknut is suited for low- to medium-pressure plumbing and fluid distribution lines. The lead-free brass construction meets regulatory requirements for potable water applications. Plumbers and pipefitters install this part where a secure, leak-tight locknut is needed on 1\/4 inch threaded pipe connections.\u003c\/p\u003e\n\u003cp\u003eThis locknut is used in residential and light commercial plumbing systems wherever a 1\/4 inch FNPT threaded connection requires mechanical securing of a fitting, valve body, or tank fitting. Common install scenarios include water supply lines, compressed air distribution, and general fluid handling systems operating within the Class 125 pressure range. Its compact size makes it well suited for tight mechanical spaces where a standard wrench can still engage the hex profile.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free brass construction meets potable water compliance requirements\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch FNPT end connection for standard threaded pipe assemblies\u003c\/li\u003e\n  \u003cli\u003eClass 125 pressure rating at 125 psi\u003c\/li\u003e\n  \u003cli\u003eBrass material resists corrosion in water and air service applications\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suited for tight-clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement locknut for 1\/4 inch FNPT threaded pipe fittings in Class 125 plumbing and fluid distribution systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed plumbers or pipefitters in accordance with local plumbing codes and IPC guidelines. Shut off and depressurize the line before removing or installing any threaded fittings. Use an appropriate pipe wrench or open-end wrench to tighten the locknut — do not overtighten, as brass threads can be damaged by excessive torque. Apply thread sealant or PTFE tape to mating threads as required by the application and local code.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1\/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: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: XNL119-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51541567766834,"sku":"XNL119-04","price":16.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4b5809d0dc4914894c1c3cdf5d792f1_02de9c8b-988f-470b-9fa1-9954a3151ae8.jpg?v=1785879351","url":"https:\/\/voomisupply.com\/products\/merit-brass-xnl119-04-brass-pipe-locknut-1-4-in-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
