It is designed to seal the open end of a threaded pipe or fitting in piping systems where corrosion resistance and a secure, tool-driven closure are required. The square head profile allows a wrench or socket to apply consistent torque, making it suitable for pressurized service up to 150 psi. Plumbers, pipefitters, and mechanical contractors install this type of plug during system commissioning, testing, and line isolation work.\u003c\/p\u003e\n\u003cp\u003eThis plug fits residential and light commercial plumbing, HVAC hydronic systems, compressed air lines, and industrial process piping where a 1-1\/2 inch MNPT threaded terminus must be closed. Its 304 stainless steel construction resists oxidation and is appropriate for water, mildly corrosive fluids, and clean air service. It is sold individually and is well suited for both new installation and maintenance applications where a durable, reusable plug is preferred over a disposable plastic cap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel construction provides corrosion resistance for wet and mildly aggressive service environments\u003c\/li\u003e\n  \u003cli\u003eSquare head profile allows wrench or socket installation for consistent seating and reliable sealing\u003c\/li\u003e\n  \u003cli\u003eMNPT threaded connection mates with standard female NPT fittings and pipe threads\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi for use in pressurized plumbing, hydronic, and compressed air lines\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch fitting size covers a common pipe size in commercial and residential mechanical systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard MNPT threaded pipe plug for use in any female NPT-threaded pipe, fitting, or valve body with a 1-1\/2 inch port, consistent with 150 psi class fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters in accordance with applicable plumbing codes such as the IPC or IFGC. Depressurize and drain the affected line before removing or installing any threaded pipe plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation to ensure a leak-free seal. Do not over-torque; use a properly sized wrench on the square head to avoid distorting the plug or damaging the mating female threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Square Head Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4SQ11\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716398088498,"sku":"4SQ11\/2","price":25.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd54684c6a97bd2f97c118a152906e47.jpg?v=1788525419","url":"https:\/\/voomisupply.com\/products\/value-collection-4sq11-2-square-head-pipe-plug-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
