Fabricated from hot dip galvanized steel at 26 gauge, this fitting delivers corrosion resistance and structural rigidity expected in commercial and residential duct installations. The elbow measures 4 inches in diameter on both the inlet and outlet, making it a straight-size fitting with no transition. HVAC installers and sheet metal contractors use this component when routing round duct through tight spaces or when a hard 90-degree turn is required in a supply or return air trunk system.\u003c\/p\u003e\u003cp\u003eThis elbow is suited for residential and light commercial forced-air HVAC applications where round galvanized ductwork is the specified system type. It fits standard 4-inch round duct collar connections and is appropriate for use in supply branches, exhaust runs, and ventilation layouts that require a 90-degree change of direction. The hot dip galvanized finish makes it a reliable choice in unconditioned spaces such as attics, crawlspaces, and mechanical rooms where moisture exposure is a consideration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree angle provides a hard directional change for round duct runs\u003c\/li\u003e\n\u003cli\u003eHot dip galvanized steel construction resists corrosion in unconditioned spaces\u003c\/li\u003e\n\u003cli\u003e26 gauge material thickness meets standard ACCA and SMACNA fabrication requirements\u003c\/li\u003e\n\u003cli\u003e4-inch diameter on both ends — no transition, no reducer required\u003c\/li\u003e\n\u003cli\u003eRound profile compatible with standard round duct collars and snap-lock fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for standard 4-inch round galvanized duct systems in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal contractors. Power down the air handling equipment before connecting or modifying any duct section. Secure the elbow with sheet metal screws and seal all joints with UL 181-listed duct tape or mastic sealant per SMACNA and local mechanical code requirements. Do not use this fitting in high-pressure or high-velocity duct systems beyond its design rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Thickness\u003c\/strong\u003e: 26 Gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize A (Inlet Diameter)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize B (Outlet Diameter)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 90-26GA_4IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283970228530,"sku":"90-26GA_4IN","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309276920.jpg?v=1781064575","url":"https:\/\/voomisupply.com\/products\/southwark-metal-90-26ga_4in-round-duct-elbow-90-deg-4-in-26-ga","provider":"Voomi Supply","version":"1.0","type":"link"}
