Insulated 4" Gray Flex Hose R4.2

Atco #070, 076, and 078 are UL 181, Class 1 Air Ducts and are manufactured with a tri-directional fiberglass scrim reinforced, grey polyester outer jacket.

The inner core of all three products is air-tight and designed for low-to-medium operating pressures in HVAC systems.

Atco #076 and 078 have increased insulation for superior thermal performance.

A double lamination of tough polyester which encapsulates a steel wire helix forms the air-tight inner core of the Atco #070, 076, and 078.

The double-layer core of each product is wrapped in multiple thicknesses of fiberglass insulation. All three products are sheathed in a rugged and durable tri-directional reinforced, grey polyester jacket.
