Its hollow core construction follows a regular plug profile, providing reliable closure in low- and medium-pressure applications. The square head design allows wrench engagement for secure installation and removal. Plumbers, pipefitters, and mechanical contractors install this fitting during system assembly, maintenance, and pressure testing. It meets Federal Specification WW-P-471-B, ANSI B-16.14 for dimensions, and ANSI B-2.1 for pipe threads, confirming dimensional and thread-form compliance with industry standards.\u003c\/p\u003e\u003cp\u003eThis pipe plug is suited for residential and commercial plumbing, steam, gas, and general industrial piping applications where a threaded pipe end must be capped or blanked off. It is typically installed in ferrous piping systems using NPT tapered pipe threads. The malleable iron construction offers impact resistance and workability compared to cast iron, making it appropriate for systems that may experience vibration or thermal cycling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/2 inch NPT threaded square head plug for standard pipe fittings\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction provides strength and impact resistance\u003c\/li\u003e\n\u003cli\u003eHollow core regular plug design for reliable pipe end sealing\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI B-16.14 dimensional standards and ANSI B-2.1 pipe thread standards\u003c\/li\u003e\n\u003cli\u003eMeets Federal Specification WW-P-471-B for ferrous plugs, bushings, and locknuts\u003c\/li\u003e\n\u003cli\u003eSquare head allows firm wrench grip during installation and removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fitting for 1-1\/2 inch NPT threaded ferrous piping systems in plumbing, steam, and general industrial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and ASME or IFGC standards. Shut off and depressurize the piping system fully before installing or removing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads prior to installation to ensure a leak-free joint. Do not overtighten; use a properly sized pipe wrench to achieve a snug, code-compliant fit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Square Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Design\u003c\/strong\u003e: Hollow Core (Regular Plug)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: ANSI B-2.1 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensional Standard\u003c\/strong\u003e: ANSI B-16.14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFederal Specification\u003c\/strong\u003e: WW-P-471-B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.53 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASC ENGINEERED SOLUTIONS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8700159455\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51343862890802,"sku":"8700159455","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547644.jpg?v=1782025136","url":"https:\/\/voomisupply.com\/products\/asc-8700159455-black-iron-square-head-pipe-plug-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
