This fitting features a female National Pipe Taper (FNPT) end connection and carries a 150 psi pressure rating. It is designed to join a pipe to a vessel, tank wall, or flat surface where only one threaded end is required. Licensed plumbers and pipefitters install this type of fitting in industrial, commercial, and marine plumbing applications where corrosion resistance is a priority. The 316 stainless steel alloy provides enhanced resistance to chlorides and acidic media compared to 304-grade material.\u003c\/p\u003e\n\u003cp\u003eThis half coupling suits residential and commercial piping systems that require a durable, corrosion-resistant threaded connection at a pipe terminus or equipment tap. It is well suited for use in chemical processing, marine, food service, and general-purpose plumbing where stainless steel is specified. The FNPT threading allows direct connection to standard NPT male-threaded pipe or fittings. At 0.15 pounds, this compact fitting is easy to handle and install in tight spaces. The ISO-compliant construction meets internationally recognized dimensional standards for interchangeable installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction resists corrosion in chloride-rich and acidic environments\u003c\/li\u003e\n  \u003cli\u003eFNPT end connection threads directly onto standard male NPT pipe\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating suitable for low-to-medium pressure piping systems\u003c\/li\u003e\n  \u003cli\u003eISO-compliant dimensions for consistent, interchangeable fit\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch fitting size covers a common pipe size used across plumbing and process systems\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.15 pounds for easy single-hand 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 half coupling for 3\/4-inch NPT threaded piping systems requiring a 316 stainless steel FNPT fitting.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC or ASME B31 piping codes. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply a compatible thread sealant or PTFE tape to male NPT threads before engagement; do not apply sealant to the female threads of this coupling. Hand-tighten first, then use appropriate pipe wrenches to achieve a leak-free connection without over-torquing the stainless steel threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Half Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/4 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\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: 0.15 pounds\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: K611H-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51540531642674,"sku":"K611H-12","price":15.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/606f8468b1fc61da8f6ea81a801dbfa9.jpg?v=1785857635","url":"https:\/\/voomisupply.com\/products\/merit-brass-k611h-12-half-coupling-3-4-in-316-ss-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
