Sean's Choice 5.9 inch/6 inch Portable Air Conditioner Exhaust Hose Coupler Window Adapter A/C Unit Tube Connector Mobile air Conditioning Accessories Round

The Portable Air Conditioner Exhaust Hose Coupler is an accessory designed to extend the exhaust duct for a mobile air conditioner. It is a square to round connector that may help extend the ducting that came with the unit. The connector has mixed reviews from several customers, with many complaining that it does not fit as expected. Some customers have found that it fits nicely and that it works perfectly as described. However, a few customers have found that the accessory is too big or does not fit any adapter as the company recommends. The coupler is well-built and feels solid, but it may not be compatible with all brands of machines or window kits.
