Water pipe insulation.

Would Not Recommend

It does exactly what it is supposed to do and it's very easy product to use.

Fits well, even able to slide into tight spots

Would Recommend

Worked out looking better than I thought. Would’ve been 5 stars but, they should include 4-5 zip ties to complete the job. Noticeable increase in cooling on my old r22 system on hot days. Condenser sits in the sun most of the day
