Built from hot dip galvanized steel, this fitting delivers a 90-degree turn at a consistent 18 inches x 8 inches cross-section on both the inlet and outlet. The radius throat design reduces turbulence and static pressure loss compared to square-throat fittings. It is installed by sheet metal workers and HVAC technicians as part of low-pressure supply or return trunk systems in forced-air heating and cooling applications.\u003c\/p\u003e\n\u003cp\u003eThis elbow fits residential and light commercial forced-air HVAC systems where rectangular trunk ductwork requires a 90-degree direction change without a size transition. The Broadway flat profile suits installations with limited ceiling or plenum clearance. Both the inlet and outlet measure 18 inches x 8 inches, making it a straight-size fitting with no reduction. It is appropriate for new construction and retrofit duct systems fabricated to SMACNA and ACCA standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree angle for perpendicular trunk duct routing\u003c\/li\u003e\n  \u003cli\u003eConsistent 18 inches x 8 inches size on both ends — no taper or transition\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in conditioned air applications\u003c\/li\u003e\n  \u003cli\u003eFlat, Broadway profile suited for low-clearance plenum and ceiling chase installations\u003c\/li\u003e\n  \u003cli\u003eRadius throat design reduces airflow turbulence and static pressure loss\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for rectangular trunk duct systems requiring a 90-degree flat elbow at 18 inches x 8 inches.

Secure the fitting to adjoining ductwork using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per local mechanical code requirements. Power down the air handling equipment before connecting to or modifying any section of the duct system. Ensure the fitting is adequately supported per applicable mechanical code to prevent sagging or joint separation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A (Inlet)\u003c\/strong\u003e: 18 inches x 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B (Outlet)\u003c\/strong\u003e: 18 inches x 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Flat, Broadway, Radius Throat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\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: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14_18X8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284091240754,"sku":"14_18X8","price":52.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277374.jpg?v=1781068321","url":"https:\/\/voomisupply.com\/products\/southwark-metal-14_18x8-trunk-duct-elbow-18x8-90-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
