Locknuts are used to secure fittings, nipples, and threaded pipe through panels, bulkheads, or tank walls by threading onto the fitting from the back side and tightening against the surface to create a firm mechanical hold. The Class 125 pressure rating makes this locknut suitable for a wide range of low- to moderate-pressure water, gas, and general plumbing service applications. Brass construction provides corrosion resistance and reliable thread engagement in both commercial and residential piping systems. Plumbers and pipefitters install this type of fitting as part of standard threaded pipe assemblies.\u003c\/p\u003e\n\u003cp\u003eThis locknut is designed for use in residential and light commercial plumbing, HVAC condensate systems, water distribution, and general fluid-handling applications where a 1-1\/2 inch FNPT threaded locknut is required. It is suited for panel or bulkhead mounting applications where a pipe or fitting must be anchored securely through a wall or enclosure. The FNPT threading is compatible with standard NPT-threaded pipe and fittings commonly found in domestic plumbing and mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch fitting size for standard NPT threaded pipe assemblies\u003c\/li\u003e\n  \u003cli\u003eFemale NPT (FNPT) end connection on both mating surfaces\u003c\/li\u003e\n  \u003cli\u003eClass 125 pressure rating suitable for low- to moderate-pressure service\u003c\/li\u003e\n  \u003cli\u003eBrass construction offers corrosion resistance and durable thread engagement\u003c\/li\u003e\n  \u003cli\u003eCompact locknut profile for panel and bulkhead mounting applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service locknut for 1-1\/2 inch FNPT threaded pipe and fitting assemblies in residential and commercial plumbing systems rated at Class 125.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter following applicable IPC or local plumbing code requirements. Shut off and depressurize the line before disassembling any threaded connection. Use a pipe wrench or strap wrench to tighten the locknut firmly against the mounting surface without overtightening, which can crack brass fittings. Apply thread sealant tape or compound appropriate for the service fluid before making up the threaded joint.\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: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\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\u003eWeight\u003c\/strong\u003e: 0.51 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: X119-24\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51540527055154,"sku":"X119-24","price":22.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d9ecdb98fbc5b7156950fee1c18b5c9.jpg?v=1785857534","url":"https:\/\/voomisupply.com\/products\/merit-brass-x119-24-brass-pipe-locknut-1-1-2-in-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
