Built from hot dip galvanized steel at 24 gauge, it connects a 12-inch diameter duct to a 10-inch diameter duct. The tapered design maintains smooth airflow through the transition, reducing turbulence and static pressure loss. This reducer is manufactured to ACCA and SMACNA standards, making it appropriate for commercial and residential duct systems where code-compliant fittings are required. Sheet metal contractors and HVAC installers use this fitting in trunk-and-branch and spiral duct layouts.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used wherever a round spiral duct system requires a concentric diameter reduction, such as transitioning off a main trunk or stepping down branch runs. It is suited for residential forced-air systems and light commercial HVAC applications using round spiral ductwork. The 12-inch to 10-inch sizing is common in supply-side trunk reductions and large-branch connections. Installers working with spiral duct systems will find this fitting compatible with standard spiral pipe and fittings in the same gauge range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTapered concentric reducer transitions 12-inch diameter duct to 10-inch diameter duct\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in conditioned and unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003e24 gauge material thickness meets SMACNA duct construction standards for round spiral duct\u003c\/li\u003e\n  \u003cli\u003eManufactured to ACCA and SMACNA applicable standards for code-compliant installations\u003c\/li\u003e\n  \u003cli\u003eSmooth tapered interior profile minimizes static pressure loss through the transition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fitting for round spiral duct systems using 12-inch and 10-inch diameter pipe.

Secure the fitting to adjoining spiral pipe using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA guidelines. Always shut down and de-energize the air handling unit before making connections in the duct system. Do not reduce airflow beyond design parameters without verifying system static pressure with a manometer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 24 Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarger End Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmaller End Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Tapered Reducer\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: SP58-24GA_12X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283944046898,"sku":"SP58-24GA_12X10","price":37.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277997.jpg?v=1781063828","url":"https:\/\/voomisupply.com\/products\/southwark-metal-sp58-24ga_12x10-spiral-pipe-reducer-24ga","provider":"Voomi Supply","version":"1.0","type":"link"}
