Make Sure It Fit: Make sure your original hose diameter is 5.9 inches/15cm from the outer edge to the outer edge, which means it can fit most portable air conditioners. Our AC exhaust vent has an anti-clockwise thread direction so make sure to check this is correct for your AC before purchasing. Length Adjustable Hose: The shortest length of the exhaust vent is 16 inches/40cm and can be extended up to 80 inches/ 200 cm, easy to stretch and shrink, which makes it stored without occupying extra space when not in use. .
