The plug expands from an unexpanded diameter of 4.251 inches to a fully expanded diameter of 4.724 inches, creating a secure mechanical seal inside the pipe bore. It is rated for a maximum working pressure of 9 psi and features a 1\/2-inch stem diameter for tightening with standard hand tools. Plumbers, pipefitters, and mechanical contractors use this type of plug when blanking off pipe ends without permanent fittings.\u003c\/p\u003e\n\u003cp\u003eThis expansion plug is suited for residential and commercial plumbing, drainage, and mechanical piping systems where a temporary or semi-permanent seal is needed on open pipe ends. Typical applications include pressure testing drain lines, capping unused branch connections, and isolating pipe sections during repair or renovation work. The all-aluminum construction keeps the plug lightweight while resisting corrosion in wet environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExpands from 4.251 inches to 4.724 inches to seat firmly inside the pipe bore\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure of 9 psi for low-pressure sealing applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch stem diameter accepts standard wrench or socket drive\u003c\/li\u003e\n  \u003cli\u003eAluminum construction provides corrosion resistance and a lightweight profile\u003c\/li\u003e\n  \u003cli\u003eMechanical expansion design eliminates the need for adhesives or permanent fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use expansion plug for pipe bores with an internal diameter in the range of 4.251 to 4.724 inches, typical of nominal 4-inch pipe schedules in plumbing and mechanical piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by plumbers or pipefitters. Before inserting the plug, confirm the pipe bore is clean and free of debris that could compromise the seal. Insert the unexpanded plug into the pipe opening and tighten the stem with a wrench until the plug seats firmly against the pipe wall. Do not exceed the 9 psi rated working pressure, and always depressurize the system before removing the plug.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExpanded Size\u003c\/strong\u003e: 4.724 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnexpanded Size\u003c\/strong\u003e: 4.251 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 9 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.06 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: AP04.50\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698786206002,"sku":"AP04.50","price":85.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04db647d68650d5b5095ca736a3e9279.jpg?v=1788367903","url":"https:\/\/voomisupply.com\/products\/value-collection-ap04-50-aluminum-expansion-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
