It steps down from a 3\/4-inch female thread on one end to a 3\/8-inch female thread on the other, allowing a seamless transition between pipe sizes within a single fitting. The galvanized steel construction provides corrosion resistance suited to water supply, gas distribution, and general mechanical piping applications. Licensed plumbers and pipefitters are the primary installers of this type of fitting in both new construction and retrofit work.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is intended for use in residential and light commercial threaded pipe systems where a size reduction is needed between two straight runs. Common applications include water supply lines, low-pressure gas piping, and industrial or mechanical systems using standard NPT-threaded black or galvanized pipe. The fitting is sold in packages of 20 units, making it practical for contractors stocking a service van or completing larger installations requiring multiple connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 3\/4-inch to 3\/8-inch female NPT threads in a single fitting\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction for corrosion resistance in wet or exposed environments\u003c\/li\u003e\n  \u003cli\u003eStandard threaded connection compatible with NPT pipe systems\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 20 for job-site efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-use fitting for residential and commercial threaded galvanized or black iron pipe systems using 3\/4-inch and 3\/8-inch NPT connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed plumbers or pipefitters in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water or gas supply and depressurize the line before making any connections. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten threaded fittings, as this can crack the fitting or damage 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 (female NPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3\/8 inches (female NPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.33 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 20\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: 511-342HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51562482368818,"sku":"511-342HC","price":41.94,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec7769076a8e7b00d607768b428292ef.jpg?v=1786477881","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-511-342hc-galvanized-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
