Square head plugs are used to close off threaded pipe openings in pressurized piping systems. The external male threads engage a female-threaded fitting or pipe end, and the square drive head allows a wrench to apply full seating torque without rounding. A105 carbon steel construction makes this plug suitable for high-pressure and elevated-temperature service common in industrial and mechanical piping. Plumbers, pipefitters, and mechanical contractors install these fittings during system assembly, pressure testing, and port isolation work.\u003c\/p\u003e\u003cp\u003eThis plug fitting is used in threaded piping systems where a port, branch outlet, or unused opening must be sealed. Typical applications include dead-end closures on headers, isolation of unused tee branches, and blanking of test ports in steam, water, gas, and oil piping systems. The 1-1\/4 inch size addresses mid-range pipe diameters common in commercial mechanical and light industrial installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch nominal size for mid-range threaded pipe connections\u003c\/li\u003e\n\u003cli\u003eASTM A105 carbon steel construction rated for high-pressure and elevated-temperature service\u003c\/li\u003e\n\u003cli\u003eSquare head drive allows full wrench engagement for proper torque application\u003c\/li\u003e\n\u003cli\u003eMale NPT threads seal threaded female fittings and pipe ends\u003c\/li\u003e\n\u003cli\u003eSuitable for steam, water, gas, and oil piping applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style threaded plug for 1-1\/4 inch female NPT threaded fittings and pipe ends in standard carbon steel piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed pipefitters or plumbers in accordance with applicable mechanical and piping codes such as ASME B31.1 or B31.3. Depressurize and isolate the piping system completely before installing or removing any threaded plug. Apply appropriate thread sealant or PTFE tape to the male threads before seating. Use a wrench on the square head to achieve proper engagement without overtightening, which can crack fittings or damage threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A105 Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Square Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male NPT\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FIBRE-METAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69029108993\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FIBRE-METAL","offers":[{"title":"Default Title","offer_id":51268871651634,"sku":"69029108993","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913996.jpg?v=1780708264","url":"https:\/\/voomisupply.com\/products\/fibre-metal-69029108993-square-head-plug-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
