Threaded with a 4-inch male pipe thread (MPT) connection on a 4-8 thread specification, this plug provides a secure, leak-resistant seal in demanding industrial and commercial applications. Weighing 8.444 pounds, the forged steel construction delivers the wall strength and durability required for high-pressure service. Licensed plumbers, pipefitters, and mechanical contractors install this fitting as a permanent or semi-permanent line termination point.\u003c\/p\u003e\u003cp\u003eThis square head plug is suited for use in forged steel fitting assemblies across industrial process piping, commercial plumbing, HVAC hydronic systems, and gas distribution lines where a robust threaded closure is required. The 4-inch MPT size makes it appropriate for larger-diameter pipe runs where standard hex plugs may not provide adequate torque surface. The square head drive allows a pipe wrench or adjustable wrench to apply the installation torque needed for a proper seal at this pipe size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch MPT connection provides a male-threaded closure for standard NPT female fittings\u003c\/li\u003e\n\u003cli\u003eForged steel construction offers high mechanical strength and pressure resistance\u003c\/li\u003e\n\u003cli\u003e4-8 thread specification for reliable thread engagement at large pipe diameter\u003c\/li\u003e\n\u003cli\u003eSquare head drive accepts pipe wrench or adjustable wrench for high-torque installation\u003c\/li\u003e\n\u003cli\u003eHeavy-duty weight of 8.444 pounds reflects solid forged steel wall thickness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard forged steel fitting for use with 4-inch female NPT pipe connections in commercial and industrial piping assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this fitting should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where relevant. Depressurize and drain the line completely before removing or installing any threaded pipe fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not use a cheater bar or impact tool that could over-stress the fitting threads or connected pipe.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MPT (Male Pipe Thread)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 4-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Forged Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.444 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 107681\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950076494130,"sku":"107681","price":105.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60a6c9f0e1b752ca1f4c6ecf10128ccc.jpg?v=1791706406","url":"https:\/\/voomisupply.com\/products\/midland-industries-107681-square-head-plug-4-in-mpt","provider":"Voomi Supply","version":"1.0","type":"link"}
