Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 plug provides a reliable, pressure-tested closure for 3-inch threaded pipe ends. The square head profile allows for standard wrench engagement during installation and removal. It is a common component in commercial and industrial piping assemblies installed by licensed plumbers and pipefitters.\u003c\/p\u003e\n\u003cp\u003eThis square plug is suited for use in residential and commercial piping systems where a threaded pipe terminus must be capped and sealed. Typical applications include shutoff points, pressure test ports, and service connections in water, gas, and low-pressure steam distribution lines. The malleable iron construction handles the mechanical stress and thermal cycling common in these environments. It is installed wherever a Class 150 threaded plug is required per system design or code specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction for strength and resistance to mechanical stress\u003c\/li\u003e\n  \u003cli\u003eThreaded end connection compatible with standard pipe threads\u003c\/li\u003e\n  \u003cli\u003eRated 300 psi for liquid and gas service\u003c\/li\u003e\n  \u003cli\u003eRated 150 psi for steam service\u003c\/li\u003e\n  \u003cli\u003eClass 150 fitting, FM Approved and cULus Listed\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 7\/1 threading standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 3-inch Class 150 threaded malleable iron piping systems handling liquid, gas, or low-pressure steam.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the piping system completely before installing or removing any threaded plug. Apply thread sealant or PTFE tape appropriate for the service medium before threading the plug into the fitting. Do not overtighten, as malleable iron threads can be damaged by excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating (Liquid\/Gas)\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating (Steam)\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.85 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: FM Approved, cULus Listed, ISO 7\/1\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: G291 80\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723289723186,"sku":"G291 80","price":23.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6919b665d639db9070d97f7ff22f9023.jpg?v=1788602714","url":"https:\/\/voomisupply.com\/products\/value-collection-g291-80-malleable-iron-square-plug-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
