It transitions from a 1.5-inch inlet to a 1-inch outlet, making it a practical choice for reducing flow path diameter within threaded pipe systems. The hot-dip galvanized finish provides corrosion resistance in wet or exposed environments. Plumbers and pipefitters install this fitting in water supply, drainage, and general-purpose piping systems where a concentric pipe-size reduction is required without adding additional fittings.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial plumbing applications. It is commonly used in water distribution lines, irrigation systems, and mechanical room piping where threaded galvanized steel pipe is the specified material. The 1.5-inch by 1-inch size reduction is a standard transition found in supply branch lines, boiler rooms, and utility piping. Installers working with Schedule 40 threaded galvanized pipe will find this a direct-fit solution for inline diameter reduction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanized steel construction provides corrosion resistance in wet and exposed piping environments\u003c\/li\u003e\n  \u003cli\u003eReduces from 1.5-inch inlet to 1-inch outlet in a single inline fittingThreaded connections compatible with standard NPT threaded galvanized pipe\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 4 units per order quantity\u003c\/li\u003e\n  \u003cli\u003eCompact coupling profile minimizes added run length in tight installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for threaded galvanized steel pipe systems using NPT connections in residential and commercial plumbing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and depressurize the water supply before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly, and tighten with a pipe wrench to proper engagement without over-torquing the fitting. Inspect threads for damage before installation to ensure a leak-free joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1 inch\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: 3.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 4 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: 511-375HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51558483820850,"sku":"511-375HN","price":22.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c134ea987596ed7ebfb14e3130de1c4.jpg?v=1786413504","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-industries-511-375hn-galvanized-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
