Rated 4.0 out of 5 by 2 reviewers.
Rated 4.0 out of 5.0 by Works, but upsize for PVC Stopped my AC condensate line from dripping all over the attic! It insulates well, but the sizing is misleading. The matching size of pipe insulation is listed to work with PVC, and I didn't think to check the elbows for compatability with PVC as well (so I guess the mistake is partly on me). The equivalent-sized pipe insulation works for 3/4" PVC pipe, but the elbow joint insulation is too narrow for that size of PVC fitting. So I found out the hard way that it's no good for 3/4" PVC joints. I ended up cutting up some extra foam, shoving it in the gap, and then taping everything on. So if you're buying for PVC, buy the next size up. November 15, 2013
Rated 4.0 out of 5.0 by My store had multiple variations - some good, some only ok Check the adhesive before you buy, I got some with an all white UPC that the UPC and starter tape didn't peel off of well. It wasn't serious, but it peeled away some of the material and distorted the cover a little. I'm not sure if they were old stock or what, the other ones I got had a blue header on the UPC label and everything worked great on those ones. They're all usable but the blue label ones worked way easier. December 15, 2014
