Flexduct 560C R6 Flex Air Duct 5 in X 25 Ft Fiberglass

Product Description

The FLEXDUCT 560C is a UV-inhibited fiberglass flexible air duct rated R6 for thermal insulation. Measuring 5 inches in diameter and 25 feet in length, it is designed for use in residential and light commercial HVAC distribution systems. The fiberglass construction and R6 insulation value help reduce heat gain and heat loss through supply and return air runs. The black outer jacket provides UV resistance, making it suitable for installations where incidental light exposure may occur. Licensed HVAC technicians install this product as part of forced-air ducting layouts connecting air handlers, plenums, and supply registers.

This flex duct is sized at 5 inches in diameter and ships in a 25-foot bag, making it well suited for residential split systems and packaged units where branch runs require a compact duct diameter. The R6 insulation rating meets common energy code minimums for unconditioned space installations such as attics and crawlspaces. The fiberglass inner liner supports airflow while the insulation wrap and black outer jacket complete the assembly for typical above-ceiling and under-floor duct routing applications.

Key Features

• R6 insulation rating for reduced heat transfer in unconditioned spaces
• 5-inch diameter accommodates standard branch run fittings and collars
• 25-foot length per bag reduces splice points in longer runs
• UV-inhibited black outer jacket resists degradation from light exposure
• Fiberglass construction provides lightweight, flexible routing through framing and joists

Compatibility

Designed as an OEM-style replacement and new-installation flex duct for residential and light commercial forced-air HVAC systems requiring a 5-inch diameter R6-insulated flexible duct.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with ACCA Manual D and local mechanical codes. Power down the air handling unit at the disconnect before making duct connections. Secure each end of the flex duct with approved draw bands and mastic or foil tape rated for duct applications. Avoid sharp bends or excess compression of the duct liner, as these conditions reduce effective airflow and insulation performance.
