Made from malleable iron, this 3\/4 inch trade size fitting provides a durable, concrete-tight connection at conduit joints. It is non-insulated and relies on threaded engagement for mechanical and electrical continuity. Electricians use this fitting in both exposed and embedded conduit runs where a reliable, code-compliant joint is required.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for commercial and industrial electrical installations using 3\/4 inch rigid steel conduit or IMC. It is commonly installed in conduit systems run through concrete slabs, walls, and structural members where a concrete-tight fitting is specified. The threaded connection ensures a secure mechanical joint without additional fasteners or tools beyond standard conduit wrenches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction for durability in demanding installation environments\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type for secure, wrench-tight conduit joints\u003c\/li\u003e\n  \u003cli\u003eRated concrete-tight for embedment in concrete pours and masonry applications\u003c\/li\u003e\n  \u003cli\u003eNon-insulated design for standard metallic conduit grounding continuity\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch trade size fits standard 3\/4 inch rigid and IMC conduit threads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fitting for 3\/4 inch trade size rigid metal conduit and intermediate metal conduit (IMC) threaded raceway systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before working on any conduit system. Thread the coupling fully onto both conduit ends using a strap wrench or pipe wrench to achieve a wrench-tight fit. Do not overtighten to the point of cracking the fitting, as malleable iron can fracture under excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Conduit Type\u003c\/strong\u003e: Rigid Metal Conduit, Intermediate Metal Conduit (IMC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation\u003c\/strong\u003e: Non-Insulated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArea of Application\u003c\/strong\u003e: Concrete Tight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 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: THOMAS BETTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 676-TB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51539446464818,"sku":"676-TB","price":55.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcfe364ee51642a00385a54ff137c9c8.jpg?v=1785840432","url":"https:\/\/voomisupply.com\/products\/thomas-betts-676-tb-conduit-coupling-3-4-in-malleable-iron-imc","provider":"Voomi Supply","version":"1.0","type":"link"}
