It transitions from a 1\/2-inch female thread on one end to a 3\/8-inch female thread on the other, allowing a reduction in line size without additional fittings. The galvanized steel construction provides corrosion resistance suitable for water supply, gas distribution, and general plumbing applications. Licensed plumbers and pipefitters install this fitting in residential and light commercial systems where threaded iron pipe is standard. It ships in a package of 5 units.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in threaded galvanized pipe systems where a line size change is required mid-run. Common applications include water supply lines, natural gas distribution piping, and compressed air systems that use standard NPT-threaded black or galvanized iron pipe. It is appropriate for both new construction and repair or retrofit work in residential and light commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1\/2-inch female NPT to 3\/8-inch female NPT in a single fitting\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction resists corrosion in wet and humid environments\u003c\/li\u003e\n  \u003cli\u003eStandard NPT threads ensure compatibility with common threaded pipe and fittings\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 5 units for shop stock or service truck inventory\u003c\/li\u003e\n  \u003cli\u003eCompact coupling profile minimizes added length to the pipe run\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard stocking fitting for threaded galvanized iron pipe systems using 1\/2-inch and 3\/8-inch NPT connections.\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 local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the supply line before removing any existing fittings. Apply an approved thread sealant or PTFE tape to the male threads before making up the joint. Do not over-tighten threaded joints, as this can crack fittings 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: 1\/2 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: 0.74 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 units\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: 511-332HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51559027736882,"sku":"511-332HN","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc42b197b3e282222e03a971cb4c488f.jpg?v=1786426137","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-511-332hn-galvanized-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
