The flexible core allows for routing through tight spaces, framing cavities, and attic runs where rigid ductwork is impractical. The R6 insulation rating provides thermal resistance suitable for unconditioned spaces such as attics and crawlspaces. The acoustical lining reduces airborne noise transmission between the air handler and supply registers, making it well suited for bedroom and living area applications. This duct ships in a 25-foot length and measures 6 inches in diameter.\u003c\/p\u003e\u003cp\u003eThis flexible duct is used in forced-air heating and cooling systems to connect branch runs from the plenum or trunk line to supply boots and registers. The 6-inch diameter is a common size for individual room supply runs in residential construction and retrofit work. HVAC installers use it in new construction, renovation projects, and system replacements where flexible duct is specified or preferred over rigid sheet metal branch lines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eR6 insulation rating suitable for unconditioned attic and crawlspace installations\u003c\/li\u003e\n\u003cli\u003eAcoustical inner lining reduces airborne noise from airflow and system operation\u003c\/li\u003e\n\u003cli\u003e6-inch diameter fits standard 6-inch collars, boots, and flex connectors\u003c\/li\u003e\n\u003cli\u003e25-foot length per section reduces the number of joints needed on longer runs\u003c\/li\u003e\n\u003cli\u003eFlexible core allows routing around obstructions and through framing cavities\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 supply branch runs requiring a 6-inch diameter acoustical flex duct with R6 insulation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFlexible duct installation is typically performed by licensed HVAC technicians. Power down the air handler and close the disconnect before connecting to any plenum or trunk line collar. Avoid sharp bends, kinks, and compression of the duct, as these conditions significantly reduce airflow and system efficiency. Secure all connections with approved clamps or draw bands and mastic or listed tape per local mechanical codes and SMACNA guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Rating\u003c\/strong\u003e: R6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Acoustical Flexible Duct\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: 1mr6.0-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLEXMASTER","offers":[{"title":"Default Title","offer_id":51267846799666,"sku":"1MR6.0-6","price":168.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912035.jpg?v=1780692011","url":"https:\/\/voomisupply.com\/products\/flexmaster-1mr6-0-6-acoustical-flex-duct-r6-6in-25ft","provider":"Voomi Supply","version":"1.0","type":"link"}
