It features a straight, threaded connection and is non-insulated, making it a direct, no-frills mechanical coupling for joining conduit runs at termination points. Electricians use this fitting where two conduit ends must be connected without rotating either section of conduit. The all-steel construction is rated for both hazardous and non-hazardous area applications, giving it broad site versatility across industrial, commercial, and utility installations.\u003c\/p\u003e\n\u003cp\u003eThis female union is suited for rigid IMC conduit systems in commercial and industrial environments where code-compliant, threaded mechanical connections are required. Typical install scenarios include panel feeds, junction box connections, and inline conduit repairs where a union-style fitting allows the conduit run to be broken and reassembled without disturbing adjacent sections. Its hazardous location rating makes it applicable in classified areas such as Class I or Class II environments where metallic conduit methods are required by the NEC.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThreaded connection for secure, code-compliant coupling to rigid and IMC conduit\u003c\/li\u003e\n  \u003cli\u003eFemale union design allows conduit sections to be disconnected and reconnected without rotation\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides mechanical strength and durability in demanding environments\u003c\/li\u003e\n  \u003cli\u003eNon-insulated straight connector for standard metallic raceway continuity\u003c\/li\u003e\n  \u003cli\u003eRated for both hazardous and non-hazardous area applications\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch trade size for common branch circuit and feeder conduit runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded fitting for 1-1\/4 inch trade size rigid metal conduit (RMC) and intermediate metal conduit (IMC) systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC Article 344 for rigid metal conduit or Article 342 for IMC. De-energize all circuits and lock out the system before beginning conduit work in live panels or junction enclosures. Apply listed thread-sealing compound or thread tape appropriate for steel conduit threads when installing in wet or hazardous locations. Do not over-tighten threaded connections, as this may damage the fitting body or 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: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Female Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConduit Type Compatibility\u003c\/strong\u003e: Rigid (RMC), Intermediate (IMC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnector Shape\u003c\/strong\u003e: Straight\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: Hazardous Location, Non-Hazardous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.45 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: THOMAS BETTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UNF 405-TB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51539155321138,"sku":"UNF 405-TB","price":233.67,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8fcbef840936629b67dcff5e3bbc6538.jpg?v=1785835587","url":"https:\/\/voomisupply.com\/products\/thomas-betts-unf-405-tb-conduit-female-union-1-1-4-in-rigid-imc","provider":"Voomi Supply","version":"1.0","type":"link"}
