5.1" & 5.9" Portable AC Exhaust Hose Telescopic Thickened Flexible Vent Duct Pipe for Mobile Air Conditioner

Keep your living space cool and energy-efficient with this Universal Portable Air Conditioner Exhaust Hose. Specially designed as a durable replacement or extension duct for mobile AC units, this flexible exhaust pipe is available in two standard industry diameters (5.1 inches / 13 cm and 5.9 inches / 15 cm). Engineered with a high-density, steel wire-reinforced structure and flexible polypropylene outer lining, it expands, contracts, and bends smoothly to fit your window vent kit setup without kinking or collapsing. Heat-resistant and leak-proof, it effectively vents hot air outside, preventing heat recirculation so your portable air conditioner operates at peak cooling performance all summer long.

Why Choose Our Portable AC Exhaust Hose

Thin, low-quality plastic AC exhaust hoses can crack under sun exposure, leak hot air back into your air-conditioned room, and collapse easily when bent. Finding an exact factory replacement from the original manufacturer can often be difficult and expensive. This thickened, wire-reinforced telescopic duct combines high-heat tolerance, universal coupler sizing, flexible length adjustment, and effortless twist-lock installation—giving your home cooling setup, mobile AC unit, and window vent kit an instant reliable upgrade.
