Product Identity

The VEVOR OW108 is a 4.25 inch insulated flexible duct designed for HVAC heating, cooling, ventilation and exhaust applications. It suits installers and homeowners needing a 25 ft run with a thermal resistance value of R-6.0. The three-layer construction provides flame resistance for safety in residential and light commercial settings.

Capacity and Headroom

The duct extends to 300 inches with a tube thickness of .98 inches in the extended state, delivering consistent airflow across the full length. An 8.66 inch width allows it to fit standard 4 inch connections while the R-6.0 rating maintains temperature integrity. Runs exceeding 25 ft or installations requiring higher thermal resistance will need additional insulation or a larger diameter duct.

Bundled Accessories

Two stainless steel clamps are included to secure the duct to vent collars or appliance outlets without separate hardware purchases. The clamps accommodate the 108 mm diameter and 165 mm outer dimension for a tight seal. No tape, hangers or additional connectors are supplied, so installers must source those separately for complex routing or code-compliant support.

Questions about this item

Will the 4.25 inch diameter fit my existing dryer vent collar?

The duct has a 4.25 inch (108 mm) diameter. Measure your collar; standard 4 inch collars accept this size with the included stainless steel clamps.

How can I verify the R-6.0 insulation is performing after installation?

Check that the three-layer wall measures about 0.98 inch thick when extended and feel for reduced heat transfer along the 25 ft run during dryer operation.

Does the box include everything needed to connect the 25 ft duct?

The package contains the flexible duct and two stainless steel clamps. No additional parts are required for a typical dryer vent connection.
