Each piece measures 2 inches inside diameter and 25 feet in length, and the box contains 4 lengths. The duct features a two-ply aluminum core wrapped in a tough aluminized mylar outer jacket that delivers an R-8.0 insulation value. It is UL181-certified as an air duct, meeting the listing requirements that most mechanical codes require for supply-side ductwork. Licensed HVAC technicians and mechanical contractors install this product in high-velocity system retrofits and new construction.\u003c\/p\u003e\n\u003cp\u003eThis flex duct is purpose-built for the Unico high-velocity small-duct system, which uses less than one-third the space of a conventional duct system and can deliver up to 9 tons of cooling capacity in the same footprint as a 3-ton traditional unit. The 2-inch diameter twist-fit design integrates directly into Unico supply plenum outlets, making it well-suited for residential and light commercial retrofit projects where space inside walls, floors, and ceilings is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUL181-certified air duct construction meets mechanical code listing requirements for supply-side installation\u003c\/li\u003e\n  \u003cli\u003eR-8.0 insulation value reduces heat gain along supply runs\u003c\/li\u003e\n  \u003cli\u003eTwo-ply aluminum core provides structural integrity and airtight performance\u003c\/li\u003e\n  \u003cli\u003eTough aluminized mylar outer wrap resists puncture and moisture during installation\u003c\/li\u003e\n  \u003cli\u003eTwist-fit end design simplifies connection to Unico plenum outlets\u003c\/li\u003e\n  \u003cli\u003eBox of 4 lengths at 25 feet each allows efficient stocking for multi-run jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the Unico high-velocity small-duct air distribution system.

Power down the air handler and verify the system is de-energized before connecting or repositioning supply duct runs. Support the duct at intervals consistent with local mechanical code requirements to prevent sagging, which can reduce airflow and system performance. Do not compress or kink the duct along its run, as this will increase static pressure and degrade system efficiency.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength per Piece\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Box\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Value\u003c\/strong\u003e: R-8.0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Construction\u003c\/strong\u003e: Two-ply aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Wrap\u003c\/strong\u003e: Aluminized mylar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL181 certified air duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Type\u003c\/strong\u003e: Round twist-fit supply flex duct\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: UNICO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: upc-25t-r8-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UNICO","offers":[{"title":"Default Title","offer_id":51468196151602,"sku":"UPC-25T-R8-4","price":1069.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946471.jpg?v=1783914121","url":"https:\/\/voomisupply.com\/products\/unico-upc-25t-r8-4-flex-duct-r8-2-in-x-25-ft-box-of-4","provider":"Voomi Supply","version":"1.0","type":"link"}
