4-Inch R-4.2 Flexible HVAC Duct

This 4-inch flexible HVAC duct is designed for HVAC professionals and facility teams routing air in low- to medium-pressure heating and cooling systems. Its insulated, expandable design helps create flexible duct runs where a 4-inch diameter is required.

The duct has a 4-inch diameter and R-4.2 insulation. Its core is bonded to a vinyl-coated spring steel wire coil that supports the fiberglass insulation. An acoustically rated polyethylene inner liner expands easily, and the inner core is self-extinguishing. The duct is mold- and mildew-resistant and is rated for temperatures from -20°F to 200°F, with intermittent exposure up to 250°F.

Key Features:

• R-4.2 Insulation: Supports insulated air distribution in compatible HVAC duct runs.
• Bonded Wire Coil Core: Helps support the fiberglass insulation while maintaining a flexible duct form.
• Expandable Inner Liner: Allows the duct to extend for routing through the installation area.
• Acoustic Inner Liner: Helps reduce duct noise during operation.
• Mold and Mildew Resistance: Helps the duct withstand mold and mildew exposure.

Choose this flexible duct for 4-inch heating and cooling applications that call for R-4.2 insulation, an expandable construction, and low- to medium-pressure performance.
