It transitions from a 3\/8-inch female thread on one end to a 1\/4-inch female thread on the other, allowing a reduction in line size without additional fittings. The galvanized steel construction provides corrosion resistance suited to general plumbing, HVAC piping, and light industrial applications. Plumbers and pipefitters install this coupling as a standard component in threaded iron or steel pipe systems.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in residential and commercial plumbing and mechanical systems where a threaded pipe run requires a step-down in size. Typical applications include water supply lines, gas distribution piping, compressed air systems, and HVAC hydronic or steam piping. It is sold in a package quantity of 30 units, making it practical for contractors stocking multiple fittings for a job or service van inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 3\/8-inch to 1\/4-inch female threaded connections in a single fitting\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction resists corrosion in typical pipe system environments\u003c\/li\u003e\n  \u003cli\u003eStandard NPT threading for compatibility with common threaded pipe and fittings\u003c\/li\u003e\n  \u003cli\u003eCompact coupling profile minimizes added length in tight pipe runs\u003c\/li\u003e\n  \u003cli\u003eSold in a 30-count package for trade use and job-site stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard trade fitting for threaded steel pipe systems using NPT connections in residential and commercial plumbing or mechanical piping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters working with threaded iron or steel pipe systems. Shut off the water, gas, or compressed air supply and depressurize the line before removing any existing fitting. Apply thread sealant tape or pipe compound to the male threads before assembly, and tighten with a pipe wrench to the appropriate engagement depth per IPC or IFGC guidelines. Do not overtighten, as this can crack or deform 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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1\/4 inches\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: 3.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 30 per package\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 INDS(IMPORT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 511-321HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51559002964274,"sku":"511-321HC","price":48.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54494d47c8334f4bbe45e0d491e395a1.jpg?v=1786425441","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-indsimport-511-321hc-galvanized-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
