The female NPT straight locknut (FNPSL) end connection provides a reliable threaded engagement rated to 150 psi. At 1-13\/16 inches in length and weighing just 0.17 pounds, this locknut is a compact but durable fastening component. The 316 stainless steel construction offers strong resistance to corrosion and chemical exposure, making it well suited for demanding service environments. Plumbers, pipefitters, and mechanical contractors install this type of hardware as part of threaded pipe runs where secure locking of fittings is required.\u003c\/p\u003e\n\u003cp\u003eThis locknut is used in threaded piping systems where a locking mechanism is needed to prevent fitting rotation or loosening under vibration or pressure. Typical applications include industrial plumbing, process piping, and mechanical systems where stainless steel is specified for corrosion resistance. The FNPSL connection conforms to ISO standards, supporting use in both domestic and internationally specified installations. It is appropriate for residential and commercial mechanical systems where 150 psi-rated threaded stainless components are called for.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction for corrosion and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eThreaded FNPSL end connection rated to 150 psi\u003c\/li\u003e\n  \u003cli\u003eISO-compliant dimensions for broad fitment compatibility\u003c\/li\u003e\n  \u003cli\u003eCompact 1-13\/16 inch length suits tight installation clearances\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.17 pounds for easy handling during installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation locknut for 1-inch threaded pipe fittings in 316 stainless steel piping assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers or pipefitters working on threaded stainless steel piping systems. Shut off system pressure and drain the line before disassembling or installing any threaded components. Use appropriate pipe wrenches or strap wrenches rated for stainless fittings to avoid galling the threads. Follow applicable IPC or IFGC code requirements and manufacturer torque guidance for threaded stainless connections.\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPSL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\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: K619-16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51542377496882,"sku":"K619-16","price":27.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/343f24b4f19daff2abda4ce8af94bd7b_75f2f564-170a-4419-b03c-a15413f4a437.jpg?v=1785899029","url":"https:\/\/voomisupply.com\/products\/merit-brass-k619-16-pipe-locknut-1-in-316-ss-threaded","provider":"Voomi Supply","version":"1.0","type":"link"}
