Diameter of the hose is 4 inches.  I saw that online it was 5 inches.  It is was too small for my air conditioner.  Unhappy with this mixup, and I don't have time to fiddle around with the wrong information causing me extra trouble.  It is going back.  I am unhappy that the seller has to "approve" the refund.  False advertising.
