Kingdder 6 Pcs Pipe Insulation Foam Tube Self Adhesive Pipe Insulation Wrap Freezing Aluminum Foil Duct Foam Protection 15mm Thick, 1.3ft for Outdoor Solar Air Conditioning Hot Water Duct(22mm)

Two months into the usage and all looks good and tight. Not difficult to install but take your time, the PSA is a one time use and sealed. The overlap is good and seems to be holding up to two months of Michigan heat and rain.

These are perfect.

Good dense foam for insulation, but poor adhesion is a real issue. I use duct tape over to hold it in place

Used to replace original missing and damaged insulation on AC tubing. Best part is that the pack rats don’t like the metal exterior. Has stopped their non-stop destruction. Also, the AC seems to cool better since these were installed.

Easy to install and stays where you put it!
