This insulation increased the cooling efficiecy of my portable 115VAC Air Conditioner unit Excellent Value!
I needed 6" diameter insulation to cover the hot plastic exhaust tube for my portable 115VAC air conditioner. This helped the efficiency of the system and worked very well on my Hisense 400-sq ft 115-Volt Portable Air Conditioner. Highly Recommend!!!
Since no adapter is provided to easily slide the insulation sleeve over the end of the pipe, it required us to make an adapter out of a 3 qt. plastic water container, which worked fine. Anything but straight runs caused voids in the insulation, but I guess that is to be expected.
