Hi All,

The foam rubber insulation on the bigger (cold one) copper line from the
compressor to the house, has deteriorated from the sun and weather. Would
like to replace it. It's about 2'.

Is there a special requirement for this insulation, or can a hot water line
insulation be used? This is the stuff commonly found at HD or similar. It
does not look quite the same, as what's on there already.

It'll work, just won't hold up as well to weather. You can get the
denser stuff at HVAC or plumbing supply.
