Quietflex 6MR6 Flexible Duct Silver Sleeve R-6.0 75 Ft

Product Description

The QUIETFLEX 6MR6 is a 6-inch diameter flexible duct section with a silver sleeve finish and an R-6.0 insulation rating. Designed for use in residential and light commercial HVAC air distribution systems, this flex duct connects supply plenums, boots, and diffusers in forced-air heating and cooling applications. Each box contains 15 pieces at 5 feet each, yielding 75 feet of flexible duct per box. Licensed HVAC technicians and sheet metal contractors install this product as part of duct system fabrication or replacement work.

This flex duct is suited for residential forced-air systems where insulated flexible duct runs are required between the air handler or furnace and the conditioned space. The R-6.0 insulation value meets common energy code minimums for unconditioned spaces such as attics and crawlspaces. The silver sleeve exterior is typical of metalized-film jacketed flex duct used in standard duct system installations. Each piece measures 5 feet in length, making them manageable for overhead and tight-space installation.

Key Features

• 6-inch inside diameter for standard residential duct sizing
• R-6.0 insulation rating suitable for unconditioned space installations
• Silver metalized sleeve exterior for durability and radiant heat resistance
• Pre-cut 5-foot sections for efficient handling and installation
• 15 pieces per box totaling 75 feet of flexible duct

Compatibility

Designed as an OEM-style flexible duct replacement for residential and light commercial forced-air HVAC duct systems requiring 6-inch diameter insulated flex duct with an R-6.0 insulation rating.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with SMACNA guidelines and applicable local mechanical codes. Power down the air handling system before making duct connections. Secure all duct connections with approved clamps or drawbands and seal with mastic or listed duct tape — standard duct tape is not approved for duct sealing. Avoid sharp bends that reduce airflow; maintain bend radii per manufacturer and code recommendations.
