Brass unions allow two pipe ends to be connected and disconnected without rotating either pipe — a key advantage in tight service spaces or systems that require periodic disassembly. Weighing 7 pounds, this union is built to handle the demands of commercial and residential installations where a reliable, leak-free threaded connection is required. Licensed plumbers and pipefitters are the primary installers for fittings of this type.\u003c\/p\u003e\u003cp\u003eThis 3-inch threaded brass union is suited for use in water distribution, heating, and mechanical piping systems where brass is the specified material. At 3 inches, it fits larger-diameter pipe runs common in commercial plumbing, boiler rooms, and institutional settings. The threaded end connections allow installation without soldering or specialized tooling beyond a pipe wrench, making it practical for retrofit and service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch threaded end connections for tool-accessible assembly and disassembly\u003c\/li\u003e\n\u003cli\u003eBrass construction offers corrosion resistance in wet piping environments\u003c\/li\u003e\n\u003cli\u003eUnion design allows line separation without disturbing adjacent pipe sections\u003c\/li\u003e\n\u003cli\u003eWeighs 7 pounds — sized for larger-diameter commercial and industrial pipe runs\u003c\/li\u003e\n\u003cli\u003eOrder increment of 1 for single-unit purchasing flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 3-inch threaded pipe connections in residential and commercial plumbing and mechanical systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off water supply and depressurize the line before removing or installing any union fitting. Apply appropriate thread sealant or PTFE tape to all threaded connections before assembly. Do not overtighten threaded brass fittings, as brass threads can be damaged by excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 675135039692\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AY MCDONALD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5422-432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AY MCDONALD","offers":[{"title":"Default Title","offer_id":51396257939762,"sku":"5422-432","price":227.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834316.jpg?v=1782828378","url":"https:\/\/voomisupply.com\/products\/ay-mcdonald-5422-432-threaded-brass-union-3-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
