Dometic R4.2 Insulated Flexible Ducting

Dometic R4.2 Insulated Flexible Ducting is flexible insulated air duct for marine air conditioning and HVAC systems. It carries conditioned air from the air handler to cabin vents and other outlets. It is also called insulated flex duct, flexible air duct or R4.2 duct hose. The insulation helps keep cooled or heated air at temperature along the run, so less energy is lost between the unit and the vent.

Key Features:

• R4.2 insulation value: a layer of wall insulation reduces thermal loss and helps limit condensation on the duct surface.
• Wire-reinforced construction: a round wire helix keeps the duct open and holds its shape through bends.
• Mylar fabric outer shell: a durable outer jacket protects the insulation.
• Flexible routing: the duct bends around obstacles, which suits the tight spaces in boats and RVs.
• Sold individually: each part number is sold as an individual duct.

The ducting is available in several internal diameters, so you can match the duct to your air handler outlet and vent requirements. It suits marine air conditioning installations and replacement of worn or damaged duct runs. Dometic is a leading name in marine and RV climate control.
