Measuring 8 inches in diameter and 25 feet in length, this flex duct connects supply air plenums and branch takeoffs to diffusers, registers, and grilles. The R-6 insulation value helps limit heat gain and heat loss across the duct run, and the acoustical construction reduces airborne noise transmission from the air handler or fan coil to the occupied space. HVAC technicians and sheet metal contractors are the primary installers of this product.\u003c\/p\u003e\u003cp\u003eThis flexible duct is suited for residential forced-air systems and light commercial applications where branch runs require noise attenuation and thermal performance. The 8-inch diameter accommodates moderate to high airflow branch runs commonly found in larger residential systems or small commercial VAV and constant-volume applications. The 25-foot length provides enough material for most single branch runs without splicing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eR-6 insulation value limits heat transfer along the duct run\u003c\/li\u003e\n\u003cli\u003eAcoustical construction attenuates airborne noise from the air-handling unit\u003c\/li\u003e\n\u003cli\u003e8-inch diameter suits moderate to high-flow branch duct applications\u003c\/li\u003e\n\u003cli\u003e25-foot length covers most single branch runs without a splice\u003c\/li\u003e\n\u003cli\u003eFlexible design allows routing around framing and obstructions in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation flexible duct for residential and light commercial forced-air HVAC distribution systems requiring R-6 insulated 8-inch diameter branch runs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFlexible duct installation is typically performed by licensed HVAC technicians or sheet metal contractors in accordance with SMACNA flexible duct installation standards and local mechanical codes. Power down and lock out the air-handling unit before connecting or disconnecting duct sections. Secure each end with an approved strap and mastic or foil tape rated for HVAC use to maintain the air seal. Avoid sharp bends, kinks, or compression, as these conditions reduce airflow and system efficiency.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 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-6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Family\u003c\/strong\u003e: 1MR6\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FLEXMASTER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1mr6.0-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLEXMASTER","offers":[{"title":"Default Title","offer_id":51268159701298,"sku":"1MR6.0-8","price":204.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912794.jpg?v=1780700756","url":"https:\/\/voomisupply.com\/products\/flexmaster-1mr6-0-8-acoustical-flex-duct-r6-8in-25ft","provider":"Voomi Supply","version":"1.0","type":"link"}
