The plug body is constructed from galvanized steel with a rubber sealing element that expands against the pipe wall when the wing nut is tightened, creating a secure, leak-free seal. At 0.475 pounds, it is lightweight enough for single-hand positioning. Licensed plumbers and plumbing inspectors rely on this type of plug to isolate sections of piping before a municipal or third-party pressure test.\u003c\/p\u003e\n\u003cp\u003eThis test plug is suited for residential and light commercial plumbing installations where 3-inch DWV pipe is present. Typical use cases include new construction rough-in inspections, remodel tie-ins, and serviceability testing at cleanout access points. The plug seats inside the pipe opening and is removed once the system passes inspection and is ready for service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch connection size fits standard DWV pipe openings\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel body resists corrosion during repeated use\u003c\/li\u003e\n  \u003cli\u003eRubber sealing element expands radially for a positive pipe-wall seal\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.475 pounds for easy single-hand placement\u003c\/li\u003e\n  \u003cli\u003eRemovable design  -  plug is extracted after testing without damage to pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style test plug for use with standard 3-inch DWV pipe systems in residential and light commercial plumbing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off all water supply and relieve system pressure before inserting or removing the plug. Tighten the wing nut by hand until the rubber element seats firmly against the pipe wall  -  do not overtighten with tools, as this can deform the rubber seal. Remove the plug only after the system has been depressurized and inspection is complete.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.475 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Rubber\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 990568\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67952088318258,"sku":"990568","price":18.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad3fe58975dcb08c883b9c783758b6dc_5cc94514-eeeb-4b12-a9cb-16edb3bb8b6c.jpg?v=1791746329","url":"https:\/\/voomisupply.com\/products\/midland-industries-990568-test-plug-3-inch-galvanized-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
