This fitting absorbs axial movement caused by temperature fluctuations, protecting the integrity of the conduit run and preventing stress fractures or joint separation. Electricians install this component in exposed or embedded conduit systems where temperature swings are significant, such as rooftop runs, outdoor service entries, and large commercial or industrial installations. The EPVC construction provides resistance to corrosion and the chemical exposure common in these environments.\u003c\/p\u003e\u003cp\u003eThis expansion joint is suited for use in commercial and industrial electrical conduit installations where long conduit runs require movement compensation. It is appropriate for surface-mounted, exposed, and concealed applications subject to thermal cycling. Licensed electricians working under NEC guidelines will encounter this fitting in large-scale conduit systems on rooftops, parking structures, and exterior building runs where conduit length and temperature variation demand expansion control.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.5-inch trade size accommodates standard EPVC conduit of that diameter\u003c\/li\u003e\n\u003cli\u003eEPVC construction offers corrosion resistance in outdoor and chemically active environments\u003c\/li\u003e\n\u003cli\u003eDesigned to absorb axial movement from thermal expansion and contraction in conduit systems\u003c\/li\u003e\n\u003cli\u003eHelps prevent joint separation and conduit stress fractures in long runs\u003c\/li\u003e\n\u003cli\u003eSuitable for commercial and industrial electrical conduit applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 3.5-inch EPVC electrical conduit systems in commercial and industrial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC requirements for conduit system expansion fittings. De-energize all circuits in the conduit run before working on the system. Secure conduit on both sides of the expansion joint according to manufacturer and code guidelines to allow proper axial movement. Do not over-cement or rigidly restrain the fitting in a way that prevents intended movement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: EPVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 622454340695\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ATKORE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EJ-312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATKORE","offers":[{"title":"Default Title","offer_id":51347814777138,"sku":"EJ-312","price":164.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553027.jpg?v=1782114329","url":"https:\/\/voomisupply.com\/products\/atkore-ej-312-epvc-expansion-joint-3-5-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
