replacing heat pump refridgerant insulation

i'm not sure if this falls under plumbing or not......

if anyone has any tips/advice to replacing the black rubber foam
type insulation on my heat pump refridgerant line
(ie. outside the house, from the heatpump to where the line
goes into the house wall)
feel free to post them.
i managed to get some insulation that is split down the middle

my plan it to remove the old cracked/worn/crumbling insulation
make sure the line is dry/clean and install the new stuff.

I may use some type of foil tape to seal the 'split' and i'll probably use
ties or stainless steel wire ties to hold the insulation in place.

Why don't you go to a local heating/air conditioning dealer and buy what you need from them? The foam pipe insulation we use on water pipes is not the same material used to insulate AC lines.

If it is the cold line, then you must use closed-cell insulation to prevent water from going through and condensing. Also, the slit must be sealed with a vapor-tight seal. That seal could be tape or adhesive or both.

Well i found the stuff to buy from a local heating/air conditioning
dealer...only he doesn't carry the product himself.
but as it turns out, ********* carries this stuff.

it not that typical foam insulation.

i managed to find some stainless steel 'zip' like ties.
i'll take the old stuff off (whats left of it),
clean it, put the new stuff on, seal the slit
and use these stainless steel ties as an extra precaution.
they use regular zip ties before.....which don't stand up to the
sunlight.

"they used regular zip ties before.....which don't stand up to the sunlight."

If you are using plastic ties in sunlight, select black. It has protection against UV, which is what kills plastic.

Some translucent plastics, such as most polyethylene tanks, are made with UV inhibitors.

A few wraps with Elec tape every 6 or 12 inches is typically what I've seen around here.
