The Item in My Kit

I bought AP Products Two-Inch Flexible Air Duct as part of my camper van equipment.

I bought this duct with the van's heating and ventilation materials. My heater diary documents the work involved in positioning the interior outlet and making a cover around it.

Air-Route Space Beside the Heater Cover

  1. I cut the heater-cover front and triangular sides from black aluminum composite sheet.
  2. I joined the panels with brackets and self-tapping screws.
  3. I fitted the cover around the angled seat platform, where drilling access affected the screw positions.

My Takeaway for the Build

The heater-cover build involved angled sides and limited room around the passenger-seat platform. That makes bend space and duct diameter useful context for my flexible-air-duct purchase. RecPro keeps the two-inch format, while the plastic alternative moves to a larger bore and a shorter supplied length.

Product Details And Van-Build Uses

SpecificationProduct Detail
Part Number013-665
Nominal Diameter2 inches
Roll Length25 feet

The AP Products 013-665 is a flexible air duct supplied as a twenty-five-foot length with a two-inch nominal diameter. Those two measurements serve different purposes: diameter identifies the connection size, while the roll length determines the available routing material. The exact product reference is useful when organizing a ventilation route through a cabinet or another interior space. The path also needs room for bends and access to the ends, rather than considering only the straight-line distance. This air-duct purchase remains distinct from a metal combustion-exhaust pipe or a differently sized heater connection.

Does Twenty-Five Feet Describe The Duct Diameter?

No. The recorded diameter is two inches; twenty-five feet is the supplied length.

Two Alternatives to Compare

RecPro provides another two-inch flexible foil duct. The plastic heater and defroster hose is two-and-a-half-inch inside diameter and six feet long, offering a different size and construction for a separate air-route design.
