It connects two sections of pipe using female NPT threads on both ends, making it suitable for joining straight runs in pressurized piping systems. With a pressure rating of 150 psi and compliance with ISO standards, this coupling is built for reliable service in demanding environments. The 316 stainless steel construction provides superior corrosion resistance compared to 304-grade material, particularly in chloride-rich or chemically aggressive media. Plumbers, pipefitters, and mechanical contractors are the primary installers of this fitting.\u003c\/p\u003e\n\u003cp\u003eThis coupling is well suited for use in industrial, commercial, and marine piping systems where corrosion resistance and pressure integrity are critical. Common applications include process piping, chemical transfer lines, food and beverage systems, and coastal or offshore installations where saltwater exposure is a factor. The FNPT x FNPT configuration is a standard connection type that integrates easily into existing threaded piping runs without special tooling beyond conventional pipe wrenches and thread sealant.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction for enhanced corrosion resistance in aggressive environments\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for straightforward threaded installation\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating suitable for a wide range of commercial and industrial piping applications\u003c\/li\u003e\n  \u003cli\u003eISO-compliant dimensions ensure interchangeability with other standard threaded fittings\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch fitting size covers larger-diameter pipe runs common in commercial and industrial systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 2-1\/2 inch threaded piping systems requiring 316 stainless steel construction and FNPT connections rated to 150 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes such as the IPC. Shut down and fully depressurize the piping system before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads being engaged; do not over-tighten, as this can crack fittings or damage threads. Inspect threads on mating pipe ends for damage before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 2-1\/2 inches\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: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.4 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: K611-40\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51540167754034,"sku":"K611-40","price":128.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34436a631890af055d6ade5f0f46f0b2_631da7ec-42bd-45df-9f90-a077e3dd7bef.jpg?v=1785847767","url":"https:\/\/voomisupply.com\/products\/merit-brass-k611-40-pipe-coupling-2-1-2-in-316-ss-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
