The locknut features an integrated PVC seal that compresses against the enclosure surface during installation, blocking moisture intrusion at the entry point. The steel body carries a zinc finish for corrosion resistance, and the yellow color aids visual identification during inspection. This fitting is specified for raintight electrical conduit installations where weather-exposed or damp-location enclosures require a secure, sealed conduit termination.\u003c\/p\u003e\n\u003cp\u003eThis locknut is used in residential and commercial electrical installations wherever conduit must terminate at a box, panel, or enclosure with an unthreaded knockout. Typical applications include outdoor electrical enclosures, service entrance installations, wet-location junction boxes, and any conduit run requiring a raintight connection at the enclosure wall. The 1-inch trade size accommodates standard 1-inch threaded conduit. It is installed by licensed electricians working with rigid metal conduit or intermediate metal conduit systems in raintight applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated PVC seal provides raintight performance at conduit-to-enclosure connections\u003c\/li\u003e\n  \u003cli\u003eSteel body with zinc finish for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1-inch trade size fits standard 1-inch threaded conduit\u003c\/li\u003e\n  \u003cli\u003eDesigned for unthreaded knockouts in boxes and enclosures\u003c\/li\u003e\n  \u003cli\u003eYellow color for easy visual identification during inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style raintight locknut for use with 1-inch threaded conduit terminating at unthreaded openings in standard electrical boxes and enclosures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC requirements for raintight fittings at wet or damp locations. De-energize all circuits before working in or around any enclosure. Thread the conduit into the fitting, then thread the locknut onto the conduit and tighten against the enclosure wall until the PVC seal compresses evenly and a raintight connection is achieved. Do not overtighten to the point of deforming the PVC seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Yellow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Sealing Locknut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 781747001436\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: BRIDGEPORT FITTINGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRIDGEPORT FITTINGS","offers":[{"title":"Default Title","offer_id":51267839394098,"sku":"143","price":689.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308909027.jpg?v=1780691835","url":"https:\/\/voomisupply.com\/products\/bridgeport-fittings-143-steel-sealing-locknut-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
