Look for the cover of the refrigeration line sticking out from the external wall to the condensor. Help plz?

Question

This refrigeration line is for the central air conditioner. I had it, but it was old and when the house was remodeled I threw it away. I want to replace it with the new one to cover the refrigeration line. Thank you.

Answer 1

I assume you are looking to replace the insulation on the low pressure line (the larger one) that runs from the condensing unit to the wall of the house. This "pipe" insulation comes in various sizes so you will need to know the outside diameter of the pipe. This type of insulation is specific for exterior use. You may not find at a home center/harware store. You may need to go to an Air Conditioning supply store to get the right type. The ones at the home center will work for a while, but the exterior environment will cause them to fall apart at a faster rate than the correct type.

Answer 2

If it was this black sponge like covering over the bigger of the two copper lines,you can buy it hardware stores, home stores, etc. If you cannot find it in the ac section of the store, sometimes it is located where the regular insulation is for doors etc.
