Installed a humidifier in an unheated ceiling. This insulation slides over 1/4” copper easily. Make sure you use this on a NEW line, it’s not cut down the side. Protected my humidifier water supply line from freezing down to 0F this winter, even when some of the other PEX lines froze up. Definitely works at low temp, easy install, looks good. Time will tell on durability

This was just what I needed, and for a good price! The copper lines are no longer condensating.

The measurements are very deceptive, and it comes rolled up, so part of it is bent and unusable, and it is not split like in the description. It also arrived very late. I might be able to use it if I cut it in half and zip tie two halves together. Otherwise I am going to return it.

The insulation is not split for installation like the picture and video show. This is false advertising.

They were not split all the down the length of the tube. There was only about 4 inches that was split. It was easy enough to use a utility knife and split them, but they are not exactly as advertised. I would still recommend them. They are well made and insulate quite well.

It's lengths of pipe insulation. Closed cell so it will shed water. Works as it should. The price was right, it fits good and seems thick enough to do what's needed. Super easy to use. Id buy it again

So probably not using it as a manufacturer thought I used it to insulate my fuel lines and my old Jaguar xjs with notorious fuel vaporization issues. I did of course wrap these in heat reflecting tubes and not just exposed. It's been a few months now and the insulating properties eliminated any issues that the car had. We're talking under hood temperatures approaching 250° easily on the large V12 engine. So if you're using these to insulate pipes in your house you will have no problems that I can foresee. Have a wonderful holiday season
