The coupling transitions from a 3\/4-inch inlet to a 1\/2-inch outlet, allowing plumbers and pipefitters to step down pipe size without additional adapters. The hot-dip galvanized finish provides corrosion resistance suited for water supply, compressed air, and light industrial piping runs. This type of fitting is a standard component in commercial and residential plumbing rough-in work and is installed by licensed plumbers and pipefitters.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in threaded galvanized pipe systems found in residential, commercial, and light industrial applications. Typical install scenarios include domestic water distribution, natural gas supply lines where local code permits galvanized fittings, compressed air distribution, and general mechanical piping. The fitting is sold in a package quantity of 15, making it practical for service trucks and job-site inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 3\/4-inch to 1\/2-inch nominal pipe thread in a single fitting\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish for corrosion resistance in water and air service environments\u003c\/li\u003e\n  \u003cli\u003eThreaded ends accept standard NPT pipe connections\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 15 for efficient job-site stocking\u003c\/li\u003e\n  \u003cli\u003eCompact form factor simplifies installation in tight spaces\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 standard 3\/4-inch to 1\/2-inch NPT threaded galvanized pipe systems in plumbing, compressed air, and light mechanical piping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter using NPT pipe dies, a pipe wrench, and thread sealant or PTFE tape rated for the service fluid. Shut off and depressurize the supply line fully before removing or installing any threaded fitting. Follow applicable codes such as the IPC or IFGC for approved fitting materials and joint methods in the intended service. Do not overtighten, as excessive torque can crack the fitting or distort threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 3\/4 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1\/2 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.65 pounds (package of 15)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: B K Mueller Industries\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 511-343HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51558921666866,"sku":"511-343HN","price":29.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/076e0561a3110514c8c75f248ea2b823.jpg?v=1786422976","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-511-343hn-galvanized-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
