The coupling accepts standard threaded conduit ends and provides a secure, continuous raceway for wire and cable protection. Its threaded design also allows use with chase nipples and threaded connectors to bond conduit runs to junction boxes and electrical enclosures. Licensed electricians and electrical contractors install this coupling as part of above-ground and in-wall rigid conduit systems in commercial and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for use in commercial, industrial, and heavy residential electrical installations where rigid metal conduit or IMC is specified. It connects directly to 4-inch threaded conduit ends and can serve as a transition component when used alongside appropriate threaded connectors to tie flexible metal conduit or liquid-tight conduit into a rigid conduit system. The standard threaded design ensures compatibility with all common threaded fittings used in these conduit systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch threaded interior accepts standard rigid conduit and IMC conduit ends\u003c\/li\u003e\n  \u003cli\u003eJoins two threaded rigid or IMC conduit sections end to end\u003c\/li\u003e\n  \u003cli\u003eCompatible with chase nipples and threaded connectors for box or enclosure connections\u003c\/li\u003e\n  \u003cli\u003eWorks with threaded connectors to transition from flexible metal conduit or liquid-tight conduit into rigid conduit runs\u003c\/li\u003e\n  \u003cli\u003eStandard threaded design fits all common threaded conduit fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fitting for 4-inch threaded rigid metal conduit and IMC conduit systems.

De-energize all circuits in the affected raceway before beginning conduit work. Hand-tighten the coupling onto both conduit ends and use an appropriate conduit wrench to achieve a secure mechanical connection. Do not overtighten, as this may damage conduit threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Standard threaded (rigid conduit thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Conduit Types\u003c\/strong\u003e: Rigid Metal Conduit, IMC, Flexible Metal Conduit (with threaded connectors), Liquid-Tight Conduit (with threaded connectors)\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: SOUTHWIRE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RC400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51383094870322,"sku":"RC400","price":32.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671807.png?v=1782587963","url":"https:\/\/voomisupply.com\/products\/southwire-rc400-4-inch-rigid-conduit-coupling-imc-emt","provider":"Voomi Supply","version":"1.0","type":"link"}
