Sized at 3\/8 inch with female NPT (FNPT) end connections, this locknut threads onto standard NPT fittings and pipe to secure and lock components in place against vibration, movement, or pressure. Rated at 125 psi, it is suited for low-to-medium pressure applications. Weighing approximately 0.04 pounds, the X119-06 is a compact, lightweight hardware item typically installed by licensed plumbers and pipefitters during rough-in or trim-out phases of a project.\u003c\/p\u003e\n\u003cp\u003eThis locknut is used in residential and light commercial piping systems where a threaded NPT connection must be mechanically locked. Common applications include securing fittings at valve packing glands, compression assemblies, and supply line connections. The FNPT threading allows direct engagement with standard male NPT pipe threads without additional adapters. It is sold in packages of 1 unit with a minimum order quantity of 6 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch FNPT threaded connection for standard NPT pipe and fittings\u003c\/li\u003e\n  \u003cli\u003eClass 125 pressure rating at 125 psi for low-to-medium pressure service\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in water and fluid piping systems\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.04 pounds for easy handling and installation in tight spaces\u003c\/li\u003e\n  \u003cli\u003eThreaded locknut design mechanically secures fittings against loosening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard hardware fit for residential and commercial threaded NPT piping assemblies using 3\/8 inch brass fittings 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 in accordance with applicable IPC or local plumbing codes. Shut off the water supply and depressurize the line before installing or replacing any pipe locknut. Use appropriate pipe wrenches or open-end wrenches sized for the fitting — do not overtighten, as brass threads can be damaged by excessive torque. Inspect mating NPT threads for damage or debris before threading the locknut into place.\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: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\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 \/ Finish\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 6\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: X119-06\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51542469509426,"sku":"X119-06","price":57.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03017119de293122b816388658df2941.jpg?v=1785901163","url":"https:\/\/voomisupply.com\/products\/merit-brass-x119-06-brass-pipe-locknut-3-8-in-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
