Seal each end of the tubing
Wipe off the condensation and wrap a few winds of the sticky poly tape on the tubing where it exits the house. Then dry and wrap the service valve on the condenser end of the tubing. Squeeze it in tight around the tubing.
Condensation that forms on your outdoor A/C lines reduces efficiency and raises your energy costs. So you need to install new insulation. Start by peeling off all the old foam insulation.. Then measure the outside diameter on the larger of the two tubes (the skinny tube doesn’t need insulation). Unfortunately, you won’t find the right insulation at any home center. Instead, contact a refrigeration supply house or online supplier for new foam and insulating tape (Insul-Lock tubing insulating foam, and Nomaco Poly Tape, both from pexsupply.com
