Imperial MEA-0825-6 Flexible Air Duct R-6.0 8in X 25ft

Product Description

The IMPERIAL MFG GROUP USA INC MEA-0825-6 is a flexible air duct rated R-6.0, designed for use in heating, ventilation, and air conditioning systems. It measures 8 inches in diameter and comes in a 25-foot length, making it suitable for longer duct runs without splicing. The inner core is constructed from a 2-ply polyester laminated liner that resists tearing and holds its shape under repeated flexing. The outer jacket is a fiberglass-reinforced metalized layer that adds structural support and protects against puncture. This duct is sold as a single unit and is intended for installation by licensed HVAC technicians.

The MEA-0825-6 is used in residential and light commercial HVAC applications where flexible duct is required to connect branch lines from plenums, take-offs, or air handlers to diffusers and registers. The 8-inch diameter accommodates standard trunk-to-branch transitions in forced-air systems. Its silver metalized jacket suits installations in attics, crawlspaces, and mechanical rooms where a durable, Class 1-rated flexible duct is specified. The 25-foot length provides enough run for most single-zone branch connections without the need for additional connectors.

Key Features

• R-6.0 thermal insulation rating for energy-efficient airflow in conditioned and unconditioned spaces
• 2-ply polyester laminated inner core resists unraveling and maintains duct integrity under flex stress
• Fiberglass-reinforced metalized outer jacket provides puncture resistance and structural strength
• UL 181 and ULC S-110M listed, Class 1 Air Duct rated for compliant installations
• 8-inch diameter by 25-foot length suits standard branch duct runs in forced-air systems
• Silver finish compatible with typical HVAC mechanical room and attic installations

Compatibility

Suitable for use with heating, ventilation, and air conditioning systems. Designed as a Class 1 flexible air duct replacement or new-installation component for residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and SMACNA flexible duct installation standards. Power down and lock out the air handling unit before connecting or disconnecting duct sections. Secure both ends with approved duct clamps and mastic or UL 181-listed tape — standard cloth duct tape does not meet code for this application. Avoid sharp bends that reduce internal diameter and restrict airflow; maintain the manufacturer-recommended bend radius throughout the run.
