The silver sleeve construction provides a vapor barrier and reflects radiant heat, while the R-6.0 insulation value reduces thermal loss through the duct wall. Each box contains 75 feet of flexible duct in 15 individual 5-foot pieces, giving installers manageable lengths for branch runs and transitions. HVAC technicians use this product to connect supply or return air plenums to registers, diffusers, and grilles.\u003c\/p\u003e\n\u003cp\u003eThis flexible duct connector is suited for supply air branch runs in forced-air systems where routing around framing, mechanical obstructions, or tight plenum spaces is required. The 8-inch diameter fits standard trunk-to-branch fittings and register boot connections common in residential new construction and retrofit applications. The 5-foot piece format also works well for short connector runs between rigid duct sections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR-6.0 insulation value limits heat transfer through the duct wall in unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eSilver sleeve exterior serves as a vapor retarder and reflects radiant energy\u003c\/li\u003e\n  \u003cli\u003e8-inch inner diameter fits standard round fittings, boots, and collars\u003c\/li\u003e\n  \u003cli\u003e75 feet per box in 15 pre-cut 5-foot sections for easy handling on the job\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit flexible duct section for residential and light commercial forced-air HVAC systems using 8-inch round duct connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with SMACNA flexible duct installation standards and applicable local mechanical codes. Power down the air handling unit and close the system before making duct connections. Secure each end of the flex duct with an approved clamp or draw band and seal with mastic or UL-listed foil tape — never use standard cloth duct tape. Avoid sharp bends, compression, or sags in the installed run, as these conditions significantly reduce airflow and system efficiency.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation R-Value\u003c\/strong\u003e: R-6.0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Length Per Box\u003c\/strong\u003e: 75 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePieces Per Box\u003c\/strong\u003e: 15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Per Piece\u003c\/strong\u003e: 5 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExterior Jacket\u003c\/strong\u003e: Silver sleeve\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: QUIETFLEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8MR6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"QUIETFLEX","offers":[{"title":"Default Title","offer_id":51344617046322,"sku":"8MR6","price":23.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554619.png?v=1782038002","url":"https:\/\/voomisupply.com\/products\/quietflex-8mr6-flexible-duct-connector-8-in-r-6-0-75-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
