It transitions from a 1-1\/2 inch female thread to a 3\/4 inch female thread, making it a standard fitting for reducing line size within a run of pipe. This type of coupling is commonly installed by licensed plumbers and pipefitters working on water supply, gas distribution, or general mechanical piping systems. The galvanized finish provides corrosion resistance suited to exposed or damp environments. Each package contains 4 couplings.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in residential and commercial plumbing and mechanical piping applications where a threaded connection must transition from 1-1\/2 inch to 3\/4 inch pipe. Typical installations include water distribution mains, branch lines, and general-purpose threaded pipe assemblies. The galvanized coating makes it appropriate for above-ground or indoor applications where corrosion resistance is required. It is sold in a package quantity of 4 units, making it practical for service vans and repair stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1-1\/2 inch to 3\/4 inch female threaded connection\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eThreaded ends for standard NPT pipe assembly\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 4 units\u003c\/li\u003e\n  \u003cli\u003eSuitable for water supply, gas, and general mechanical piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fitting compatible with standard NPT threaded pipe systems using 1-1\/2 inch and 3\/4 inch pipe sizes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter following applicable IPC or local plumbing code requirements. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten threaded connections, as this can crack or distort the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Female NPT Threaded Both Ends\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.65 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: B K\/Mueller Industries\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 511-374HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51557555044658,"sku":"511-374HN","price":20.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f32b85d7702e7357333cad418107318.jpg?v=1786390811","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-industries-511-374hn-galvanized-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
