Vent Hot Air Out the Window: 15cm Flat Joint Exhaust Duct for Portable Air Conditioners

A portable air conditioner only cools well when the hot exhaust actually leaves the room. This 15cm flat-joint duct replaces a cracked or ill-fitting original hose and channels warm air toward the window. The flat mouth sits flush against window seal panels, leaving fewer gaps for hot air to leak back in. Measure your unit's outlet diameter and confirm the joint type matches before ordering.
