WARM TIPS: Step 1 - Make sure your original hose's diameter is 5 inch / 13 cm (from outer edge to outer edge). Step 2 - Facing your hose， make sure it has a clockwise threading direction. Please double check the diameter and screw direction with pictures on the left before purchase.
STRETCH AND SHRINK FREELY: The shortened length is 16 inch / 40 cm. You can extend it to 78 inch / 198 cm max. E578 exhaust hose is longer than the original hose making it more flexible to use in a large space.
QUICK INSTALLATION: Stretch the hose gently. Line up one of the ends with the window connector and rotate the connector clockwise to snap into the hose. Then rotate the hose clockwise to the hose connector or the vent on the AC.
UNIVERSAL & DURABLE: Made of environmentally friendly polypropylene， no odor. Sturdy and long-lasting. A perfect replacement for your cranked portable AC exhaust hose. Fits most popular portable air conditioner models using a 5-inch diameter vent， like Honeywell， Black Decker， Whynter， LG， JHS， etc.
