K-FLEX USA 3/4" x 6 ft. Elastomeric Pipe Insulation

Absolutely what I needed to insulate the 3/4" copper line on the outside going to the air conditioner unit. The insulation was mailed promptly and it fit like a glove. Easy to install. I love the adhesive seal on the rubber tube and the adhesive overlay flap is awesome. It replaced a 10 year old insulation tube that had deteriorated and no longer insulated the copper. Just cut to length and slower peal off the adhesive tape a little at a time so as to not have it stick to everything.

Super nice for replacing the outdoor insulation on the suction line. Seals up really nicely and is very easy to put on.

Try finding this quality at your local HD. A true insulated envelope complete with its own super durable, super sticky sealing tape

The yellow strip that tapes one side to the other was in terrible shape. It did not pull of in one strip, but had deteriorated into many little pieces. They still came off fairly clean, but it was still a bit of a pita. The big fold over tape flap is pretty robust, but making it look pretty was impossible. When finished I wrapped it with UV protectant lineset tape... sold separately. Still doesn't look great but it should hold up a lot better than zip ties or duct tape.

Worked great on outside AC copper tubing that was old and cracked. Wrapped easy. Secured with black electrical tape. Sealed at the stucco level. I’m waiting to see if it makes a difference in my electric bill in 90 degree Florida weather.

Our AC line going into the house needed new installation this worked perfectly. My only ask would be to have it in longer lengths, I had to buy two pieces for my line.

Very high quality foam and the fit was perfect. the adhesion is wonderful, it has an inside piece of tape to stick the inner walls together plus a larger outer piece of tape to pull together. Best I've ever used.

I liked the idea of this insulation tube having the sealing strip to bond the seam edges of the insulation together to close the tube. Then the pre installed tape that covers the seam to keep water out and also hold the seam edges together. But I was a little dubious about how well it would actually work. Wow, this system DOES what they say and does it extremely well. The adhesive binding the seam worked great it was easy to pull off the plastic and expose the adhesive a few inches at a time and lightly squeeze the edges together. And they STAYED together. I even tugged on the sides a little and it did not budge. Then just do the same with the seam cover tape. Since that cover tape is pre-installed on one side it would be hard to screw this part up. It worked far better than I expected and took less time than writing this review. A+ product and A+ seller.
