UNIVERSAL SIZE & ADJUSTABLE LENGTH: With a diameter of 15 cm / 5.9 inches, stretched to a length of 200 cm / 78.7 inches, it can be connected to most brands of portable air conditioners. (Note: The outer diameter is 15 cm, please measure it before purchasing!)

EASY TO INSTALL: To extend the length of the air conditioner hose, align the front connection of the existing hose and turn it counter-clockwise until it clicks into place. Stay cool and comfortable in the summer heat! (The exhaust pipe threads are rotated counter-clockwise. Make sure it is the correct pipe size and thread before purchasing!)

HIGH QUALITY: The exhaust pipe is made of high-quality PP material. The inside is wrapped with spiral steel wire, which is an environmentally friendly, robust, and durable material, which has great flexibility and portability. It has super heat and abrasion resistance and will not be damaged or leak after long-term use, ensuring a longer service life.

LONG-LASTING: Our exhaust pipes are 2 m long when extended and can be shortened to 36 cm. Thanks to the internal steel spring construction that makes them stronger and less deformable, the hoses can be rotated, retracted, and stretched over a wide area without breaking or deforming.
