The hub body and locknut are copper-free aluminum, and the sealing ring is nitrile, making this fitting suitable for both indoor and outdoor installations exposed to continuous or intermittent moisture. A thermoplastic insulated throat protects conductor insulation from abrasion and reduces wire pull effort. The tapered female threaded design and captivated locknut ensure a secure, watertight, and dusttight assembly rated for use in hazardous locations. Licensed electricians performing conduit terminations in industrial and commercial environments are the primary installers of this fitting.\u003c\/p\u003e\u003cp\u003eThe H075A is rated for NEMA 3R, 4, and 13 enclosures, covering raintight, watertight, and dusttight requirements. It is listed for use in hazardous locations and carries UL and CSA approvals. The extended-reach locknut design allows clamping on thin panels up to 3\/16 inch thick. The recessed and captivated nitrile sealing ring compresses against the enclosure wall to form a reliable environmental seal without requiring a separate gasket. Typical applications include service entrance equipment, motor control centers, junction boxes, and industrial enclosures where conduit enters through a knockout-free or punched opening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTapered internal threads prevent conduit from bottoming out, ensuring a sound and repeatable assembly\u003c\/li\u003e\n\u003cli\u003eNitrile sealing ring is recessed and captivated at the box end for a reliable watertight and dusttight seal\u003c\/li\u003e\n\u003cli\u003eLocknut bonding screw provides positive ground continuity between conduit and enclosure\u003c\/li\u003e\n\u003cli\u003eCopper-free aluminum construction resists corrosion in wet and industrial environments\u003c\/li\u003e\n\u003cli\u003eThermoplastic insulated throat reduces abrasion on conductor insulation and lowers wire pull effort\u003c\/li\u003e\n\u003cli\u003eRated for hazardous locations and approved to UL and CSA standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/4-inch trade size rigid metal conduit and IMC terminating at a threadless opening in NEMA 3R, 4, or 13 rated boxes and enclosures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits and lock out the enclosure before beginning conduit termination work. Thread the conduit fully into the hub before tightening the locknut to the enclosure wall; do not allow the conduit to bottom out against the hub throat. Verify the sealing ring is seated flush against the enclosure surface and that the locknut bonding screw is tightened to establish the required ground bond.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Bulkhead, Tapered Female Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThroat Type\u003c\/strong\u003e: Thermoplastic Insulated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Dimensions\u003c\/strong\u003e: 1-21\/32 inches diameter x 1-19\/32 inches length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Panel Thickness\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub and Locknut Material\u003c\/strong\u003e: Copper-Free Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealing Ring Material\u003c\/strong\u003e: Nitrile\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Type\u003c\/strong\u003e: Locknut Bonding Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 105 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: NEMA 3R\/4\/13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstructional Features\u003c\/strong\u003e: Corrosion Resistant, Dusttight, Raintight, Watertight, Hazardous Location\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Rigid Conduit and IMC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL, CSA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: CA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: H075A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51283934150962,"sku":"H075A","price":1788.35,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279602.jpg?v=1781063583","url":"https:\/\/voomisupply.com\/products\/thomas-betts-h075a-imc-rigid-conduit-hub-3-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
