It ships in a 25-foot length with a 10-inch diameter and carries an R-8 insulation value, making it well-suited for runs where minimizing heat gain or loss is a priority. The inner core is flexible, allowing routing through tight framing bays and mechanical chases without rigid transitions. The outer foil jacket acts as a moisture barrier and provides mechanical protection against tears and punctures during and after installation. HVAC technicians and sheet metal contractors use this duct for both supply and return applications.\u003c\/p\u003e\n\u003cp\u003eThis duct is appropriate for residential forced-air systems and light commercial HVAC installations where flexible duct is permitted by the mechanical code. The R-8 insulation rating meets or exceeds energy code requirements in many climate zones, reducing the need for supplemental duct wrapping. Its 10-inch diameter suits main trunk branch runs and larger zone distribution legs. The flexible construction simplifies connections between rigid plenums or trunk lines and register boots in framed ceiling and wall cavities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR-8 insulation value for high thermal efficiency across long duct runs\u003c\/li\u003e\n  \u003cli\u003e10-inch diameter accommodates higher-volume supply and return branch runs\u003c\/li\u003e\n  \u003cli\u003e25-foot length reduces the need for mid-run splicing on standard residential runs\u003c\/li\u003e\n  \u003cli\u003eFoil jacket provides a durable moisture barrier and tear resistance\u003c\/li\u003e\n  \u003cli\u003eFlexible inner core allows routing around obstructions in framed cavities\u003c\/li\u003e\n  \u003cli\u003eSuitable for both supply and return air applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation flexible duct for residential and light commercial forced-air HVAC systems requiring a 10-inch insulated flex duct with R-8 insulation value.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with the local mechanical code and SMACNA flexible duct installation guidelines. Shut down and lock out the air handler or furnace before connecting or disconnecting duct sections. Avoid sharp bends that compress the inner liner, as restricted geometry reduces airflow and system efficiency. Secure each end with an approved draw band and mastic or foil tape rated for duct applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation R-Value\u003c\/strong\u003e: R-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJacket Type\u003c\/strong\u003e: Foil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Supply and return air\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: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10KMR8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51620491264306,"sku":"10KMR8","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b96e42a4a5e7706e7d1194941551a090_f5ca6c61-93d8-4b9d-94c2-de4a42d8ac35.jpg?v=1787343427","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-10kmr8-flex-duct-10in-r-8-25ft","provider":"Voomi Supply","version":"1.0","type":"link"}
