It provides a non-insulated, concrete-tight connection that maintains conduit system integrity in demanding installation environments. The compression connection method ensures a secure mechanical fit without requiring set screws, making it a reliable choice for contractors and electricians working in commercial and industrial settings. At 0.52 pounds, it is lightweight but built from durable steel construction suited for conduit system assemblies.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in EMT conduit installations where a concrete-tight fitting is required, such as conduit runs embedded in or passing through concrete slabs, walls, or other masonry structures. It is appropriate for both new construction and retrofit work in residential, commercial, and light industrial electrical systems. Licensed electricians and electrical contractors are the primary installers of this fitting in conduit roughing and finish work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression connection type for tool-assisted, secure mechanical engagement without set screws\u003c\/li\u003e\n  \u003cli\u003eConcrete-tight construction suitable for embedment or concrete-adjacent installations\u003c\/li\u003e\n  \u003cli\u003eSteel material provides durability and mechanical strength in conduit systems\u003c\/li\u003e\n  \u003cli\u003eNon-insulated design for standard EMT coupling applications\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch trade size fits standard 1-1\/4 inch EMT conduit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit coupling for 1-1\/4 inch trade size EMT conduit systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements for EMT conduit systems. De-energize all circuits in the conduit run before beginning work. Compression-style fittings require proper compression tool engagement to achieve a rated concrete-tight seal. Do not substitute this fitting in conduit types other than EMT without verifying compatibility with the applicable electrical code.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConduit Type\u003c\/strong\u003e: EMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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: 0.52 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: COOPER CROUSE-HINDS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 663\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":67918980448562,"sku":"663","price":22.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1d978b3509de0719dbd5c3c36db2ddc.jpg?v=1791275202","url":"https:\/\/voomisupply.com\/products\/cooper-crouse-hinds-663-emt-conduit-coupling-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
