This type of fitting is used to step duct sizes up or down along a trunk line or branch run, maintaining airflow continuity where duct sizing changes. The RE1614 is a standard sheet metal component installed by HVAC technicians during new construction ductwork layout or system modification. It is engineered to fit standard round duct sections and is identified by its 85-series designation.\u003c\/p\u003e\n\u003cp\u003eThe RE1614 is suited for residential and light commercial forced-air HVAC applications where a duct run must transition from a 16-inch diameter section to a 14-inch diameter section, or the reverse when used as an increaser. Typical install scenarios include trunk-line reductions, branch takeoff sizing changes, and equipment connection transitions. This fitting is appropriate for supply or return duct systems where round duct is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions between 16-inch and 14-inch round duct diameters\u003c\/li\u003e\n  \u003cli\u003eFunctions as both a reducer and an increaser depending on orientation\u003c\/li\u003e\n  \u003cli\u003e85-series fitting designation for standard duct system compatibility\u003c\/li\u003e\n  \u003cli\u003eDesigned for forced-air supply and return duct applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard round sheet metal duct connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style round duct fitting for residential and light commercial forced-air ventilation systems using standard 16-inch and 14-inch round duct sections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician in accordance with applicable mechanical codes, including SMACNA duct construction standards. The system should be fully powered down and the air handler shut off before modifying any duct section. Secure the fitting with sheet metal screws and seal all joints with UL-listed duct mastic or metal-foil tape to prevent air leakage. Avoid using standard cloth-backed duct tape, which is not rated for long-term duct sealing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 85\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Round Reducer-Increaser\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: AIR FLOW PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RE1614\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51345944772914,"sku":"RE1614","price":35.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554421.jpg?v=1782067095","url":"https:\/\/voomisupply.com\/products\/air-flow-products-re1614-reducer-increaser-16-to-14","provider":"Voomi Supply","version":"1.0","type":"link"}
