I have this Portable A/C tube with fittings that I no longer need. The a/c unit died and got rid of it, but found the tube, I can't remember the make or model of the a/c unit. All I needed to know was that it kept me cool during the hot summer. I thought someone else could use it, other than the garbage dump. This comes from a smoke and pet-free home. It came off a Kenmore portable air conditioner, 8400 BTU Portable Air Conditioner/Dehumidifier/Fan. Model #461-35371. 3-in-1. I'm including a picture of the ac which the tube came from. AC UNIT NOT AVAILABLE The measurements of the rectangle side is on the pictures, and the diameter of the tubing is 5" inches ( 12.7cm) A/c tube with fittings - $60 Low ballers will be ignored U.P.U./Local/Cash only/will only reserve once we confirm a time to meet, this ad has been placed on other websites ( more picture options) if the ad is up, then it's still available.
