Each section is hollow roll-formed and contains an integral synthetic resin sealant that bonds directly to metal surfaces. The sealant is rated non-flow up to 180 degrees F and retains its sealing properties indefinitely, eliminating the need for a separate field-applied sealant step. This listing includes 50 sections, each measuring 12 inches in length. Licensed sheet metal workers and HVAC mechanical contractors are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eJ Flanges are used in low-pressure rectangular duct systems where duct sections are connected using a slip-and-drive or flange-and-cleat assembly method. The integral sealant simplifies the connection process on mechanical rooms, rooftop units, and air handler takeoffs where consistent sealing across multiple duct joints is required. The 50-section pack is sized for job-site quantities typical of commercial duct fabrication runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHollow roll-formed galvanized steel construction for consistent profile and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eIntegral synthetic resin sealant eliminates separate sealant application at the joint\u003c\/li\u003e\n  \u003cli\u003eNon-flow sealant rated to 180 degrees F maintains seal integrity in warm duct environments\u003c\/li\u003e\n  \u003cli\u003eSealant retains sealing properties indefinitely under normal duct operating conditions\u003c\/li\u003e\n  \u003cli\u003eEach section is 12 inches long, packaged 50 sections per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style component for low-pressure rectangular sheet metal ductwork systems requiring J-style flange connections in commercial and residential HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed sheet metal workers or HVAC mechanical contractors following SMACNA duct construction standards. De-energize all associated air handling equipment before working on duct sections. Ensure mating duct edges are clean and free of burrs before seating the J Flange to allow the integral sealant to achieve full contact. Do not apply additional duct sealants over the integral sealant without verifying compatibility.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSealant Type\u003c\/strong\u003e: Synthetic Resin (Integral)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSealant Non-Flow Rating\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSection Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight (Profile)\u003c\/strong\u003e: 0.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 8.52 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 50 sections\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: CARLISLE HARDCAST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 308846\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARLISLE HARDCAST","offers":[{"title":"Default Title","offer_id":51525191074098,"sku":"308846","price":56.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac95a8bf32a535221ec3689388709c84.webp?v=1785466767","url":"https:\/\/voomisupply.com\/products\/carlisle-hardcast-308846-j-flange-12-inch-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
