HVAC condenser pipe wrap separated in multiple locations

Hello,

I have two HVAC units in my attic. I just noticed that the pipe wrap has separated between pieces in several locations leaving huge sections exposed and causing condensation. I plan to add a new wrap to these locations but had a few questions.

1) One of the copper tubes outer diameter measures .85. Will 3/4 in pipe wrap work for that or should I use 1 in pipe wrap? see image.

2) Why would this happen in the first place? I count on each line as many as 6 separations, exposing 4 - 5 feet of copper tubing on each unit.

Thanks for the help!

Welcome to the forums.

Refrigeration copper is usually specified by OD. That means 3/4" ACR copper is 3/4" OD. (.750)
That may be some old "B" type copper pipe.
I would use the 7/8" split foam cover there. Depot has it.

Thanks for the help. I couldn't find 7/8" split foam at my local Home Depot or Lowes, but I found a place online.
Thanks!
