Flexduct 1460 Flex Air Duct R-6 14 Inch 25 Foot

Product Description

The FLEXDUCT 1460 is a UV-inhibited fiberglass flexible air duct rated at R-6 insulation, designed for residential and light commercial HVAC distribution systems. Measuring 14 inches in diameter and 25 feet in length, this duct provides the thermal performance and flexibility needed for branch runs between supply plenums and diffusers. The R-6 insulation value helps reduce heat gain and loss through unconditioned spaces such as attics and crawlspaces. The black UV-inhibited outer jacket is suited for installations where the duct may be exposed to light. Licensed HVAC technicians and sheet metal contractors are the primary installers.

This flex duct is intended for use in forced-air heating and cooling systems where flexible branch runs are required. The 14-inch diameter makes it appropriate for higher-volume trunk-to-register runs or large diffuser drops in residential and light commercial applications. The 25-foot continuous length reduces the need for field splicing on longer runs, which helps maintain system efficiency and minimizes pressure drop across the duct section.

Key Features

• R-6 insulation rating reduces heat transfer in unconditioned spaces
• 14-inch inner diameter accommodates high-volume air distribution runs
• 25-foot length minimizes the need for mid-run splices
• UV-inhibited outer jacket extends service life in exposed or attic installations
• Fiberglass construction provides lightweight handling on the job

Compatibility

Designed as an OEM-style flexible duct for use in residential and light commercial forced-air HVAC distribution systems requiring a 14-inch diameter R-6 insulated flex duct.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with ACCA Manual D duct design standards and applicable local mechanical codes. Power down the air handling unit before connecting or repositioning any duct sections. Avoid compressing or sharp-bending the flex duct, as reduced cross-section increases static pressure and degrades airflow. Secure each end with an approved clamp and mastic or UL-listed metal tape — never use standard cloth duct tape for sealing.
