This fitting allows plumbers to isolate and pressure-test sections of a drain line during rough-in and inspection stages. The no-hub configuration connects using standard no-hub couplings and banded clamps, eliminating the need for lead and oakum joints. The integrated plug seals the test port when not in use, keeping the line ready for service. Licensed plumbers and journeyman pipefitters rely on this fitting for code-compliant DWV installations in both new construction and renovation work.\u003c\/p\u003e\u003cp\u003eThis test tee is suited for residential and light commercial plumbing applications where cast iron DWV pipe is specified. It is commonly installed in below-grade or above-slab drain runs where local codes require cast iron for noise attenuation or fire-rating compliance. The no-hub end connections accept standard 4-inch no-hub cast iron or compatible pipe, making it a straightforward fit in existing cast iron systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch no-hub cast iron construction for durable DWV service\u003c\/li\u003e\n\u003cli\u003eIntegrated test plug allows line isolation for pressure and air testing\u003c\/li\u003e\n\u003cli\u003eNo-hub ends connect with standard banded no-hub couplings\u003c\/li\u003e\n\u003cli\u003eCast iron material provides sound attenuation and long service life\u003c\/li\u003e\n\u003cli\u003eSuitable for below-grade and above-slab drain line installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for 4-inch no-hub cast iron DWV piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and depressurize the affected line before cutting into an existing system. No-hub couplings must be torqued with a torque wrench to the coupling manufacturer's specification. During testing, verify the plug is fully seated and the test section is isolated before applying air or water pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: No Hub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Drain, Waste, and Vent (DWV)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHARLOTTE PIPE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 475\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHARLOTTE PIPE","offers":[{"title":"Default Title","offer_id":51620757635378,"sku":"00475","price":143.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd80fb4eadf064ea34e862cee7f02b52.jpg?v=1787346085","url":"https:\/\/voomisupply.com\/products\/charlotte-pipe-475-cast-iron-test-tee-with-plug-no-hub-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
