Review: Very Professional Installation and Easy - This has to be the very very BEST HVAC copper tubing insulation I’ve ever used. The 7/8” diameter fit the 7/8” tubing like a glove. The best thing was the glue to seal the seams was very sticky and secure but the canvas flap that covered the seam was the best. The glue that sealed this was tough and made a neat professional job very easy.

## Questions & Answers

**Q: What size copper pipe works with this as trying to figure out outside ac insulation. what do the dimensions mean as diyer?**
A: It work with up to 7/8 pipe perfectly. With 3/4 will work as well but it will be a little loose . This is required by inspectors convine with a insulation jacket which help to protect the foam overtime and keep the cool of the AC

**Q: Is this resistant to UV light (sunlight)?**
A: I forgot to mention in my previous answer how to protect this insulation. I used 4 inch flexible ribbed drain pipe and split it lengthwise for the length of the insulation that I was using outside on my Air conditioning unit To my concrete block wall where it entered my home.. Then I merely wrapped the 4 inch drain pipe around the insulation and wire tied it about the circumference of the pipe in three or four places. This protects it from the sun and was a very inexpensive option and a neater and more secure job. Plus I already had 100 feet of flexible ribbed light weight drain pipe lying around. But it is so cheap and durable enough to last 20 or 30 years. Which should outlast the insulation.

**Q: What is the actual id of this. would be his be the beat fit for a pipe/tube with an o.d. of 7/8”? acr, iron, plumbing are all different.**
A: 7/8 OD it is no matter what type of pipe
